Configuring Channelized mode for the Cisco PA-MC-2T3+


To continue your Cisco PA-MC-2T3+ port adapter installation, you must configure the PA-MC-2T3+ interface. The instructions that follow apply to all supported platforms. Minor differences between the platforms—with Cisco IOS software commands—are noted.

This chapter contains the following sections:

Using the EXEC Command Interpreter

Replacing an Existing Port Adapter

Configuring a Channelized T3 Link

Performing a Basic Serial Interface Configuration

Checking the Configuration

Using the EXEC Command Interpreter

You modify the configuration of your router through the software command interpreter called the EXEC (also called enable mode). You must enter the privileged level of the EXEC command interpreter with the enable command before you can use the configure command to configure a new interface or change the existing configuration of an interface. The system prompts you for a password if one has been set.

The system prompt for the privileged level ends with a pound sign (#) instead of an angle bracket (>). At the console terminal, use the following procedure to enter the privileged level:


Step 1 At the user-level EXEC prompt, enter the enable command. The EXEC prompts you for a privileged-level password as follows:

Router> enable 

Password: 

Step 2 Enter the password (the password is case sensitive). For security purposes, the password is not displayed.

When you enter the correct password, the system displays the privileged-level system prompt (#):

Router#

Replacing an Existing Port Adapter

Before you remove or replace a port adapter, use the shutdown command to disable the port adapter to prevent anomalies when you remove and reinstall the port adapter. When you shut down an interface, it is designated administratively down in the show command displays.

Follow these steps to shut down an interface:


Step 1 Enter the privileged level of the EXEC command interpreter (also called enable mode). (See the "Using the EXEC Command Interpreter" section for instructions.)

Step 2 At the privileged-level prompt, enter configuration mode and specify that the console terminal is the source of the configuration subcommands, as follows:

Router# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#

Shutting Down the T3 Controller

Step 3 Shut down the T3 controller on the PA-MC-2T3+ with the controller command:

shutdown

This command sends a DS3 idle signal toward the network. You can bring the T3 controller back up with the no shutdown controller command.

Examples follow:

The example that follows is for a port adapter on a VIP in interface processor slot 1 of the Cisco 7500 series router:

Router(config)# controller T3 1/0/0
Router(config-controller)# shutdown

Router(config)# controller T3 1/0/1
Router(config-controller)# shutdown

The example that follows is for a port adapter in slot 1 of the Cisco 7200 series routers:

Router(config)# controller T3 1/0
Router(config-controller)# shutdown

Router(config)# controller T3 1/1
Router(config-controller)# shutdown


Note Both T3 ports of the PA-MC-2T3+ should be shut down before removing the port adapter.


Step 4 Verify that the two T3 ports are now shut down using the
show controller T3
command shown in the following examples:

The following example is for a PA-MC-2T3+ in port adapter slot 6 of a Cisco 7200 series router.

Router(config-controller)# end
Router# show controller T3 6/0
T3 6/0 is administratively down. 

Router# show controller T3 6/1
T3 6/1 is administratively down.

The following example is for a PA-MC-2T3+ in port adapter slot 1 of a VIP in a Cisco 7500 series router.

Router(config-controller)# end
Router# show controller T3 1/1/0
T3 1/1/0 is administratively down. 

Router# show controller T3 1/1/1
T3 1/1/1 is administratively down.

Step 5 Save the shutdown configuration to nonvolatile memory.

Router# copy running-config startup-config

Step 6 Replace the port adapter in the slot. See the "Port Adapter Removal and Installation" section on page 3-4 for more information.

Step 7 Reenable the port adapter by doing the following:

a. Repeat Step 3 to reenable an interface but substitute the no shutdown command for the shutdown command.

b. Repeat Step 4 to verify that the interfaces are in the correct state and no longer shut down. Use the
show controller T3 command.

c. Repeat Step 5 to write the new configuration to memory.
Use the copy running-config startup-config command.


For complete descriptions of software configuration commands, refer to the publications listed in the "Related Documentation" section on page viii.

Configuring a Channelized T3 Link

If you installed a new PA-MC-2T3+ or if you want to change the configuration of an existing PA-MC-2T3+ link, you must enter the privileged level of the EXEC command interpreter and then use the configure command. If you replace a PA-MC-2T3+ that was previously configured, the system recognizes the new PA-MC-2T3+ link and brings it up in its existing configuration.

After you verify that the new PA-MC-2T3+ is installed correctly (the enabled LED goes on), use the privileged-level configure command to configure the new interface. Be prepared with the information you need, such as the following:

Protocols you plan to route on each new interface

IP addresses, if you plan to configure the interfaces for IP routing

The configure command requires privileged-level access to the EXEC command interpreter, which usually requires a password. Contact your system administrator if necessary to obtain EXEC-level access.

Configuring the T3 Controller

This section provides procedures and examples for configuring the T3 controller on the PA-MC-2T3+, and includes information on the following topics:

Selecting a T3 Controller

Setting Channelized Mode for the T3 Controller

Setting the Framing Type for the T3 Controller

Specifying the Cable Length for the T3 Controller

Setting the Clock Source for the T3 Controller

Configuring MDL Messages for the T3 Controller

Examples of MDL Message Configuration

Configuring the Loopback Mode for the T3 Controller

Shutting Down the T3 Controller

Configuring T1 Lines

Selecting a T3 Controller

You must enter the following controller command, before any other configuration commands, to select the T3 controller you want to configure:

controller T3 interface-processor-slot/port-adapter-slot/T3-port for Cisco 7500 series router

controller T3 chassis-slot/T3-port for Cisco 7301 router\

controller T3 chassis-slot/T3-port for Cisco 7401ASR router

controller T3 chassis-slot/T3-port for Cisco 7200 series router

Examples of selecting the T3 controller follow:

The example that follows is for a port adapter on a VIP in interface processor slot 1:

Router# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)# controller t3 1/0/0
Router(config-controller)# 

The example that follows is for a port adapter in slot 1 of the Cisco 7200 series routers:

Router# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)# controller t3 1/0
Router(config-controller)# 

Setting Channelized Mode for the T3 Controller


Note Channelized mode is the default, so you only need to configure the T3 for channelized mode if it had previously been set to `no channelized' mode.


To configure the T3 for channelized mode, use the channelized command. The following example is for a PA-MC-2T3+ in port adapter slot 1 of a Cisco 7200 series router.

Router# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)# controller T3 1/0
Router (config)# channelized

The following example is for a PA-MC-2T3+ in port adapter slot 1 of a VIP in a Cisco 7500 series router.

Router# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)# controller T3 1/1/0
Router (config)# channelized

Change to channelized mode will cause cbus complex reset. Proceed? [yes/no]: 

When the PA-MC-2T3+ is configured for channelized T3 mode, its default MTU size is set to 1500 for compatibility with other T3 equipment and port adapters.

When the T3 controller is configured to be channelized, 28 T1 lines are created. To configure the T1 lines, refer to the "Configuring T1 Lines" section.


Caution The change in MTU sizes will cause a memory recarve and cbus complex to occur, disrupting all traffic on the router for several minutes. (This occurs only on Cisco 7500 series routers.)

The following message will be displayed when switching from unchannelized to channelized mode on Cisco 7500 series routers:

Change to channelized mode will cause cbus complex reset. Proceed? [yes/no]:

Type Y for `yes' at the end of the warning. At the prompt, type ^Z to exit. This will allow you to exit configuration mode and enter channelized mode.

Setting the Framing Type for the T3 Controller

At the prompt, specify the framing type using the controller command:

framing [c-bit | m23 | auto-detect]

You can set c-bit framing format as follows:

Router(config-controller)# framing c-bit

You can set m23 framing format as follows:

Router(config-controller)# framing m23

You can request the PA-MC-2T3+ to detect the framing type it is receiving from the far end and transmit that same framing type as follows:

Router(config-controller)# framing auto-detect

Specifying the Cable Length for the T3 Controller

At the prompt, specify the cable length using the controller command:

cablelength feet

where:

feet is a numeral from 0 to 450.

The default value is 49 feet.

An example follows:

Router(config-controller)# cablelength 40

Note For the cablelength feet command, user-specified T3 cable lengths are structured into ranges as follows: 0-49 and 50-450 to represent short and long cables.

If the numerical value entered by the user falls within the lower range, then the PA-MC-2T3+ T3 port is set for short cable output levels. If the value falls into higher range, the long cable output levels will be used.

In the preceding example, a cable length of 40 is specified, which means that the 0-49 range is used. If you change the cable length to 45, then the 0-49 range still applies. Further, if you specify a cable length of 100 or 200, the 50-450 range applies in both cases. Only moving from one range (0-49) to the other range (50-450) has an effect. The actual cable-length number you enter is stored in the configuration file. It is recommended that the actual cable length be entered to ensure future compatibility.


Setting the Clock Source for the T3 Controller

At the prompt, set the internal or line clock source for the selected T3 controller with the controller command:

clock source {internal | line}

The default is clock source internal.

Examples follow:

Instruct the PA-MC-2T3+ to use a line clock source.

The example that follows is for a port adapter on a VIP in interface processor slot 1:

Router(config)# controller T3 1/0/0
Router(config-controller)# clock source line

The example that follows is for a port adapter in slot 1 of the Cisco 7200 series routers:

Router(config)# controller T3 1/0
Router(config-controller)# clock source line

Instruct the PA-MC-2T3+ to use an internal clock source.

The example that follows is for a port adapter on a VIP in interface processor slot 1:

Router(config)# controller T3 1/0/0
Router(config-controller)# clock source internal

The example that follows is for a port adapter in slot 1 of the Cisco 7200 series routers:

Router(config)# controller T3 1/0
Router(config-controller)# clock source internal

Configuring MDL Messages for the T3 Controller

You can configure Maintenance Data Link (MDL) messages (which are defined in the ANSI T1.107a-1990 specification) on the PA-MC-2T3+.


Note MDL messages are only supported when the T3 framing is set for c-bit parity. (See the "Setting the Framing Type for the T3 Controller" section.)


To configure MDL messages, use the controller commands:

mdl {transmit {path | idle-signal | test-signal} | string {eic | lic | fic | unit | pfi | port | generator} string}

no mdl {transmit {path | idle-signal | test-signal} | string {eic | lic | fic | unit | pfi | port | generator} string}

where:

eic is the equipment identification code (up to 10 characters).

lic is the location identification code (up to 11 characters).

fic is the frame identification code (up to 10 characters).

unit is the unit identification code (up to 6 characters).

pfi is the facility identification code to send in the MDL path message (up to 38 characters).

port is the equipment port, which initiates the idle signal, to send in the MDL idle signal message (up to 38 characters).

generator is the generator number to send in the MDL test signal message (up to 38 characters).

Use the no form of this command to remove MDL messages. The default is that no MDL message is configured.

Examples of MDL Message Configuration

Examples of configuring MDL messages follow:

Enter controller configuration mode first.

The example that follows is for a port adapter on a VIP in interface processor slot 1:

Router# configure t 
Enter configuration commands, one per line. End with CNTL/Z. 
Router(config)# controller T3 1/0/0
Router(config-controller)# 

The example that follows is for a port adapter in slot 1 of the Cisco 7200 series routers:

Router# configure t 
Enter configuration commands, one per line. End with CNTL/Z. 
Router(config)# controller T3 1/0
Router(config-controller)#

Enable the MDL path message transmission as follows:

Router(config-controller)# mdl transmit path

Enable the MDL idle signal message transmission as follows:

Router(config-controller)# mdl transmit idle-signal

Enable the MDL test signal message transmission as follows:

Router(config-controller)# mdl transmit test-signal

Enter the equipment identification code as follows:

Router(config-controller)# mdl string eic router A

Enter the location identification code as follows:

Router(config-controller)# mdl string lic tst network

Enter the frame identification code as follows:

Router(config-controller)# mdl string fic building b

Enter the unit identification code as follows:

Router(config-controller)# mdl string unit abc

Enter the facility identification code to send in the MDL path message as follows:

Router(config-controller)# mdl string pfi string

Enter the port number to send in the MDL idle signal message as follows:

Router(config-controller)# mdl string port string

Enter the generator number to send in the MDL test signal message as follows:

Router(config-controller)# mdl string generator string

Configuring the Loopback Mode for the T3 Controller

With loopbacks, you can detect and isolate equipment malfunctions by testing the connection between the PA-T3+ interface and the remote T3 device such as a DS3 MUX. Remote loopback sends a command to loop the T3 line at the far end (central office). It can be used to diagnose problems with cables from the port adapter to the switching office. Network loopback loops the PA-MC-2T3+ T3 port back to the network allowing the remote end to test the connection to the PA-MC-2T3+. Local loopback loops the PA-MC-2T3+ T3 port output back to itself allowing it to be tested in isolation from the T3 cables and remote T3 equipment.

The loopback subcommand places an interface in loopback mode, which enables test packets that are generated from the ping command to loop through a remote device and cables. If the packets complete the loop, the connection is good. If not, you can isolate a fault to the remote device or cables in the path of the loopback test.

You can configure the T3 controller for loopback modes using the controller command:

loopback [local | network | remote]

The default is no loopback.

To return the T3 controller to its default unlooped condition, use the no form of the command.

Table 5-1 provides examples of the loopback {local | network | remote} command.

Table 5-1 Using loopback commands

loopback local

Sets the T3 port into local loopback mode. Local loopback loops the router output data back toward the router at the framer.

Router(config)# controller T3 10/0/0
router(config-controller)# loopback 
local	

loopback network

Sets the T3 port into network line loopback mode. Network line loopback loops the data back toward the network (before the framer).

Router(config)# controller t3 10/0/0
router(config-controller)# loopback 
network line

loopback remote1

Sends a command to the remote T3 device instructing it to loop itself back to the network (before the framer at the remote T3 device).

Router(config)# controller T310/0/0
router(config-controller)# loopback 
remote

1 Remote loopback mode works with C-bit framing only. The other loopback modes listed above work with C-bit, and M23. Refer to the "Setting the Framing Type for the T3 Controller" section for information on configuring C-bit framing.


Configuring the T3 controller to Enable Remote Loopback

Equipment customer loopback enables the PA-MC-2T3+ port adapter to respond to remote T3 loopback and T1 loopback requests it receives from the remote site, while equipment network loopback causes the PA to ignore remote T3 and T1 loopback commands.

equipment [customer | network] loopback

router(config)# controller T3 3/0
router(config-controller)# equipment customer loopback

router(config)# controller T3 3/0
router(config-controller)# equipment network loopback

Note T3 remote loopbacks are only available when you use c-bit parity framing.


Shutting Down the T3 Controller

You can shut down the T3 controller on the PA-MC-2T3+ with the controller command:

shutdown

This command sends a DS3 idle signal toward the network. You can bring the T3 controller back up with the no shutdown controller command.

Examples follow:

The example that follows is for a port adapter on a VIP in interface processor slot 1:

Router(config)# controller t3 1/0/0
Router(config-controller)# shutdown

The example that follows is for a port adapter in slot 1 of the Cisco 7200 series routers:

Router(config)# controller t3 1/0
Router(config-controller)# shutdown

Configuring T1 Lines

This section provides procedures and examples for configuring T1 lines on the T3 link of the PA-MC-2T3+, and includes information on the following topics:

Creating a Logical Channel Group on a T1 Line

Removing a Logical Channel Group from a T1 Line, page -11

Setting the Framing Format on a T1 Line

Setting the Yellow Alarm Configuration for a T1 Line

Setting the Clock Source on a T1 Line

Setting the FDL Configuration for a T1 Line

Setting Loopbacks on a T1 Line

Configuring a BER Test on a T1 Line

Sending a BER Test Pattern on a T1 Line

Viewing the Results of a BER Test

Terminating a BER Test


Note For consistency throughout the following configuration examples and whenever possible, the port addresses 1/0/0 and 1/0/0/1:1 are used for Cisco 7500 series routers and 1/0 and 1/0/1:1 for Cisco 7200 series routers.

Your PA-MC-2T3+ port addressing might be different depending on the Cisco 7200 series router chassis slot or the interface processor slot in which your VIP is installed and the VIP port adapter slot in which your PA-MC-2T3+ is installed.


Creating a Logical Channel Group on a T1 Line

You can create a logical channel group on a T1 line using the following controller command:

t1 t1-line-number channel-group channel-group-number timeslots list-of-timeslots
[speed {56 | 64}]

where:

t1-line-number is 1-28.

channel-group defines a logical channel group.

channel-group-number is 0-23.

timeslots list-of-timeslots can be 1-24 or a combination of subranges within 1-24 (each subrange is a list of timeslots of the T1 line).

speed{56 | 64} is an optional argument that specifies the speed of a time slot to be either 56 kbps or 64 kbps.

Configure logical channel group 20 on T1 line 1 and assign channelized timeslots 1 to 5 and 20 to 23.

The example that follows is for a port adapter on a VIP in interface processor slot 1:

Router(config)# controller T3 1/0/0
Router(config-controller)# t1 1 channel-group 20 timeslots 1-5, 20-23

The example that follows is for a port adapter in slot 1 of the Cisco 7200 series routers:

Router(config)# controller T3 1/0
Router(config-controller)# t1 1 channel-group 20 timeslots 1-5, 20-23

Note Each T1 link may have up to 24 channel groups with an overall limit of 128 for the 28 T1 links on each T3 port. Unused channel groups in one T3 port may not be used by the other T3 port.



Note Each channel group defined with this command causes a serial interface to be created. Refer to the "Performing a Basic Serial Interface Configuration" section for instructions on configuring these interfaces.



Note All the encapsulation formats, such as PPP, HDLC, SMDS, Frame Relay, and switching types are applicable to the serial interface and can be set using the serial interface configuration commands.


Removing a Logical Channel Group from a T1 Line

You can remove a logical channel group from a T1 line with the following controller command:

no t1 t1-line-number channel-group channel-group-number

where:

t1-line-number is 1-28.

channel-group-number is 0-23.

Remove logical channel group 10 from channelized T1 line 1.

The example that follows is for a port adapter on a VIP in interface processor slot 1:

Router(config)# controller T3 1/0/0
Router(config-controller)# no t1 1 channel-group 10

The example that follows is for a port adapter in slot 1 of the Cisco 7200 series routers:

Router(config)# controller T3 1/0
Router(config-controller)# no t1 1 channel-group 10

Note If logical channel groups had previously been configured on a port, and you switch to `no channelized' mode, first remove all channel groups before invoking the `no channelized' command.


Setting the Framing Format on a T1 Line

You can specify the T1 framing format using the controller command:

t1 t1-line-number framing {esf | sf}

where:

The default framing format is extended super frame (ESF).

t1-line-number is 1-28.

Examples follow:

Set Super Frame (SF) framing format for T1 line 6.

The example that follows is for a port adapter on a VIP in interface processor slot 1:

Router(config)# controller T3 1/0/0
Router(config-controller)# t1 6 framing sf

The example that follows is for a port adapter in slot 1 of the Cisco 7200 series routers:

Router(config)# controller T3 1/0
Router(config-controller)# t1 6 framing sf

Other options for setting Super Frame (SF) include:

router(config-controller)#t1 6 framing ?
    esf  Extended Superframe Framing format
    sf   Superframe Framing Format
 
router(config-controller)#t1 6 framing sf ?
    hdlc-idle  Specify the HDLC idle pattern on a T1
    <cr>
 
router(config-controller)#t1 6 framing sf hdlc-idle ?
    0x7E  Use 0x7E as HDLC idle pattern
    0xFF  Use 0xFF as HDLC idle pattern
 
router(config-controller)#t1 6 framing sf hdlc-idle 0x7e ?

Set ESF framing format for T1 line 16 as follows:

The example that follows is for a port adapter on a VIP in interface processor slot 1:

Router(config)# controller T3 1/0/0
Router(config-controller)# t1 16 framing esf

The example that follows is for a port adapter in slot 1 of the Cisco 7200 series routers:

Router(config)# controller T3 1/0
Router(config-controller)# t1 16 framing esf


Note Use of the 0xFF HDLC idle pattern may help prevent false yellow alarms in the remote T1 device when SF framing is used.


Setting the Yellow Alarm Configuration for a T1 Line

You can use the [no] t1 t1-line-number yellow {detection | generation} command (where t1-line-number is 1-28) to turn the detection or generation of a yellow alarm on and off. When you select SF framing, you should consider using the no t1-line-number yellow detection command to turn off yellow alarm detection, because the yellow alarm can be incorrectly detected with SF framing.

Setting the Clock Source on a T1 Line

You can set the internal or line (network) clock source for a T1 line with the controller command:

t1 t1-line-number clock source {internal | line}

where:

t1-line-number is 1-28.

The default clock source is internal.

Examples follow:

Instruct T1 line 1 to use an internal clock source.

The example that follows is for a port adapter on a VIP in interface processor slot 1:

Router(config)# controller T3 1/0/0
Router(config-controller)# t1 1 clock source internal

The example that follows is for a port adapter in slot 1 of the Cisco 7200 series routers:

Router(config)# controller T3 1/0
Router(config-controller)# t1 1 clock source internal

Instruct T1 line 16 to use a line clock source received from the network.

The example that follows is for a port adapter on a VIP in interface processor slot 1:

Router(config)# controller T3 1/0/0
Router(config-controller)# t1 16 clock source line

The example that follows is for a port adapter in slot 1 of the Cisco 7200 series routers:

Router(config)# controller T3 1/0
Router(config-controller)# t1 16 clock source line

Note Normally the T1 link should be configured to use the line clock recovered from the network. In cases where the network does not provide the clock, such as two PA-MC-2T3+ port adapters connected back-to-back, one end of the T1 link must be set to internal clock and the other end to line clock.


Setting the FDL Configuration for a T1 Line

To enable and disable 1-second transmissions of performance reports through the facility data link (per ANSI T1.403 specification), you must use the following command on both ends of the connection:

t1 t1-line-number fdl ansi

where: t1-line-number is 1-28.


Note You can use this command only when the T1 framing is ESF. Use the no form of the command to disable remote performance reports.


Setting Loopbacks on a T1 Line

If you have difficulty with the PA-MC-2T3+ configuration or installation, you can troubleshoot the port adapter using the loopback command. Specify loopback for a T1 line using the following command:

t1 t1-line-number loopback [local | network | remote]

where: t1-line-number is 1-28.


Note This command requires that you are in T3 controller mode.



Note fdl loopback commands are available only for T1 lines configured for ESF framing.


Explanations of specific loopback modes follow:

local

Loops the router output data back toward the router at the T1 framer and sends an AIS signal out toward the network.

network {line | payload}

Loops the data back toward the network before the T1 framer and automatically sets a local loopback at the HDLC controllers (line), or loops the payload data back toward the network at the T1 framer and automatically sets a local loopback at the HDLC controllers (payload).

remote line fdl {ansi | bellcore}

Sends a repeating, 16-bit ESF data link code word (00001110 11111111 for ANSI; 00010010 11111111 for Bellcore) to the remote end, requesting that it enter into a network line loopback.

Specify the ansi keyword to enable the remote line facility data link (FDL) ANSI loopback on the T1 channel, per the ANSI T1.403 specification.

Specify the bellcore keyword to enable the remote SmartJack loopback on the T1 channel, per the TR-TSY-000312 specification.

remote line inband

Sends a repeating, 5-bit inband pattern (00001) to the remote end, requesting that it enter into a network line loopback.

remote payload [fdl] [ansi]

Sends a repeating, 16-bit ESF data link code word (00010100 11111111) to the remote end, requesting that it enter into a network payload loopback. Enables the remote payload Facility Data Link (FDL) ANSI loopback on the T1 channel.

You can optionally specify fdl and ansi, but it is not necessary.


Examples of the loopback commands follow:

Set the first T1 line into local loopback.

The example that follows is for a port adapter on a VIP in interface processor slot 1:

Router# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)# controller T3 1/0/0
Router(config-controller)# t1 1 loopback local	

The example that follows is for a port adapter in slot 1 of the Cisco 7200 series routers:

Router# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)# controller T3 1/0
Router(config-controller)# t1 1 loopback local	

In the preceding examples, local loopback loops the router output data back toward the router at the T1 framer and sends an AIS out toward the network.

Set the first T1 line into network line loopback.

Configuring a BER Test on a T1 Line

Bit error rate test (BERT) circuitry is built into the PA-MC-2T3+. With BER tests, you can test cables and signal problems in the field. You can configure BER tests on each of the 28 T1 lines but only one BER test can be active at a time.

There are two categories of test patterns that can be generated by the onboard BER test circuitry: pseudorandom and repetitive. The former test patterns are polynomial based numbers and conform to the CCITT/ITU O.151 and O.153 specifications; the latter test patterns are zeros or ones, or alternating zeros and ones.

A list of the available test patterns follows:

Pseudorandom test patterns:

2^11 (per CCITT/ITU O.151)

2^15 (per CCITT/ITU O.151)

2^20 (per CCITT/ITU O.153)

2^20 QRSS (per CCITT/ITU O.151)

2^23 (per CCITT/ITU O.151)

Repetitive test patterns:

All zeros (0s)

All ones (1s)

Alternating zeros (0s) and ones (1s)

Both the total number of error bits received and the total number of bits received are available for analysis. You can set the testing period from 1 minute to 14,400 minutes (240 hours), and you can also retrieve the error statistics anytime during the BER test.


Note BER testing for the T3 link is not supported in channelized T3 mode. It is only supported for unchannelized T3 ports.


When running a BER test, your system expects to receive the same pattern that it is transmitting. To accomplish this, two common options are available:

Use a loopback somewhere in the link or network.

Configure remote testing equipment to transmit the same BER test pattern at the same time.

Sending a BER Test Pattern on a T1 Line

You can send a BERT pattern on a T1 line with the controller command. The unframed option causes the BERT pattern to use the entire T1 bandwidth including the T1 framing as well as payload bits. If "unframed" is omitted, then the T1 will be either SF or ESF framed as configured by the "T1 n framing" command and the BERT pattern will occupy only the T1 payload bits.

t1 t1-line-number bert pattern pattern interval time [unframed]

where:

t1-line-number is 1-28.

time is 1-14400 minutes.

pattern is:

0s, repetitive test pattern of all zeros (as 00000...)

1s, repetitive test pattern of all ones (as 11111...)

2^11, pseudorandom test pattern (2,048 bits long)

2^15, pseudorandom O.151 test pattern (32,768 bits long).

2^20-O153, pseudorandom O.153 test pattern (1,048,575 bits long)

2^20-QRSS, pseudorandom QRSS O.151 test pattern (1,048,575 bits long)

2^23, pseudorandom O.151 test pattern (8,388,607 bits long)

alt-0-1, repetitive alternating test pattern of zeros (0s) and ones (1s), as 01010101

Examples follow:

Send a BERT pseudorandom pattern of 2^23 through T1 line 10 for 5 minutes.

The example that follows is for a port adapter on a VIP in interface processor slot 1:

Router(config)# controller T3 1/0/0
Router(config-controller)# t1 10 bert pattern 2^23 interval 5 unframed

The example that follows is for a port adapter in slot 1 of the Cisco 7200 series routers:

Router(config)# controller T3 1/0
Router(config-controller)# t1 10 bert pattern 2^23 interval 5 unframed

Send a repetitive pattern of all ones through T1 line 10 for 14400 minutes (240 hours).

The example that follows is for a port adapter on a VIP in interface processor slot 1:

Router(config)# controller T3 1/0/0
Router(config-controller)# t1 10 bert pattern 1s interval 14400 unframed

The example that follows is for a port adapter in slot 1 of the Cisco 7200 series routers:

Router(config)# controller T3 1/0
Router(config-controller)# t1 10 bert pattern 1s interval 14400 unframed

Note You can terminate a BER test during the specified test period with the no t1 bert command.


Viewing the Results of a BER Test

You can view the results of a BER test using the controller command:

show controllers T3 slot/port-adapter/t3-port for Cisco 7500 series router

show controllers T3 chassis-slot/t3-port/t1-line-number for Cisco 7401ASR router

show controllers T3 chassis-slot/t3-port/t1-line-number for Cisco 7200 series router

where: t1-line-number is 1-28.

You can view the results of a BER test at the following times:

After you terminate the test using the no t1 bert command

After the test runs completely

Anytime during the test (in real time)

The following explains the output of the preceding command, line by line:

Output Display Line
Explanation

BERT test result (running)

This line indicates the current state of the test. In this case, "running" indicates that the BER test is still in process. After a test is completed, "done" is displayed.

Test Pattern : 2^11, Status : Sync, Sync Detected : 1

This line indicates the test pattern you selected for the test (2^11), the current synchronization state (sync), and the number of times synchronization has been detected during this test (1).

Interval : 5 minute(s), Time Remain : 5 minute(s)

This line indicates the time the test takes to run and the time remaining for the test to run.

Interval : 5 minute(s), Time Remain : 2 minute(s) (unable to complete)

For a BER test that you terminate, this line indicates the time the test would have taken to run and the time remaining for the test to run had you not terminated it; "unable to complete" signifies that you interrupted the test.

Bit Errors(Since BERT Started): 6 bits,

Bits Received(Since BERT start): 8113 Kbits

Bit Errors(Since last sync): 6 bits

Bits Received(Since last sync): 8113 Kbits

These four lines show the bit errors that have been detected versus the total number of test bits that have been received since the test started and since the last synchronization was detected. Bits and errors are only counted when the test status is "sync".



Note Unless unframed is selected, the BER test runs over the currently configured framing option for the specified T1 line (ESF or SF). Before running a BER test, you should configure the framing option that is appropriate to your application. (Refer to the "Setting the Framing Format on a T1 Line" section.)


Terminating a BER Test

You can terminate a BER test with the controller command:

no t1 t1-line-number bert

where: t1-line-number is 1-28.

Examples follow:

Terminate the BER test running on T1 line 10.

The example that follows is for a port adapter on a VIP in interface processor slot 1:

Router(config)# controller T3 1/0/0
Router(config-controller)# no t1 10 bert

The example that follows is for a port adapter in slot 1 of the Cisco 7200 series routers:

Router(config)# controller T3 1/0
Router(config-controller)# no t1 10 bert

This completes the procedures for configuring and testing T1 lines.

To check your configurations using show commands, proceed to the "Checking the Configuration" section; otherwise, proceed to the following sections to perform a basic interface configuration:

Performing a Basic Serial Interface Configuration

Performing a Basic Serial Interface Configuration


Note The Cisco 7200 VXR Port Adapter Jacket Card requires no configuration. Configure a port adapter in it as you would any other port adapter.


Following are instructions for a basic configuration: enabling an interface and specifying IP routing. You might also need to enter other configuration subcommands, depending on the requirements for your system configuration and the protocols you plan to route on the interface. For complete descriptions of configuration subcommands and the configuration options available for serial interfaces, refer to the appropriate software documentation.

In the following procedure, press the Return key after each step unless otherwise noted. At any time you can exit the privileged level and return to the user level by entering disable at the prompt as follows:

Router# disable

Router> 


Step 1 Enter configuration mode and specify that the console terminal is the source of the configuration subcommands, as follows:

Router# configuration terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#

Step 2 Specify the first interface to configure by entering the interface serial subcommand, followed by the interface address of the interface you plan to configure. Table 5-2 provides examples.

Table 5-2 Examples of the interface serial Subcommand 

Platform
Command
Example

Cisco 7200 series routers

interface serial, followed by port-adapter-slot/T3-port/
T1-line-number:channel-group number

port adapter in port adapter slot 6.

Router(config)# interface serial 
6/0/1:0
Router(config-if)#

Cisco 7301 routers

interface serial, followed by port-adapter-slot/T3-port/
T1-line-number:channel-group number

The example is for T3 port 0, T1 1, channel group 0 of a
port adapter in port adapter slot 1.

Router(config)# interface serial 
1/0/1:0
Router(config-if)#

Cisco 7304 PCI Port Adapter Carrier Card in a Cisco 7304 router

interface serial, followed by port-adapter-slot/T3-port/
T1-line-number:channel-group number

The example is for T3 port 0, T1 1, channel group 0 of a port adapter in a Cisco 7304 PCI Port Adapter Carrier Card in module slot 3 of a Cisco 7304 router.

Router(config)# interface serial 
1/0/1:0
Router(config-if)#

Cisco 7401ASR routers

interface serial, followed by port-adapter-slot/T3-port/
T1-line-number:channel-group number

The example is for T3 port 0, T1 1, channel group 0 of a port adapter in port adapter slot 1.

Router(config)# interface serial 
1/0/1:0
Router(config-if)#

VIP in Cisco 7000 series or Cisco 7500 series routers

interface serial, followed by interface-processor-slot/
port-adapter-slot/
T3-port/T1-line-number:
channel-group number

The example is for T3 port 0, T1 1, channel group 0 of a port adapter in port adapter slot 1 of a VIP in interface processor slot 4.

Router(config)# interface serial 
4/1/0/1:0
Router(config-if)#

Step 3 Assign an IP address and subnet mask to the interface (if IP routing is enabled on the system) by using the ip address subcommand, as in the following example:

Router(config-if)# ip address 10.0.0.0 10.255.255.255 

Step 4 Add any additional configuration subcommands required to enable routing protocols and set the interface characteristics.


Step 5 Reenable the interfaces using the no shutdown command. (See the "Replacing an Existing Port Adapter" section.)

Step 6 Configure all additional port adapter interfaces as required.

Step 7 After including all of the configuration subcommands to complete your configuration, press Ctrl-Z—hold down the Control key while you press Z—or enter end or exit to exit configuration mode and return to the EXEC command interpreter prompt.

Step 8 Write the new configuration to NVRAM as follows:

Router# copy running-config startup-config
[OK]
Router#

This completes the procedure for creating a basic configuration.

Checking the Configuration

After configuring the new interface, use the show commands to display the status of the new interface or all interfaces, and use the ping and loopback commands to check connectivity. This section includes the following subsections:

Using show Commands to Verify the New Interface Status

Displaying Remote Performance Reports

Using the ping Command to Verify Network Connectivity

Using show Commands to Verify the New Interface Status

Table 5-3 demonstrates how you can use the show commands to verify that new interfaces are configured and operating correctly and that the PA-MC-2T3+ appears in them correctly. Sample displays of the output of selected show commands appear in the sections that follow. For complete command descriptions and examples, refer to the publications listed in the "Related Documentation" section on page viii.

brief displays a list of configurations only.

tabular displays a list of configurations and MIB data in a tabular format.

remote performance displays a list of performance data from the remote end of a T1 connection.


Note If you use the show controllers T3 slot/port-adapter/port command without either of the three optional arguments (brief, tabular, or remote performance), all information is displayed for the T3 controller you specified; therefore, the resulting display output can be extensive.



Note You can use these three show controllers T3 commands for Cisco 7200 series, Cisco 7301 routers, and Cisco 7401ASR routers in which the PA-MC-2T3+ is supported. The syntax is as follows:

— show controllers T3 chassis-slot/T3-port brief

— show controllers T3 chassis-slot/T3-port tabular

— show controllers T3
chassis-slot/T3-port remote performance

Examples of these show controllers T3 commands for Cisco 7200 series and Cisco 7401ASR routers are not shown.


The show controllers command with no arguments displays information about every controller and interface in the router.

The following example is for a Cisco 7500 series router:

(additional displayed text not shown)


Note In the preceding example, remote performance data is unavailable.


If you use the show controllers T3 command without specifying a port address (slot/port-adapter/port/t1-line-number), all information is displayed for all 28 T1 lines within every T3 port adapter in the router; therefore, the resulting display output can be extensive.

You can also display brief configuration information or tabular configuration and MIB information about a specific T1 line within a PA-MC-2T3+ with the command:

show controllers T3 slot/port-adapter/t3-port/t1-line-number [brief | tabular | remote performance]

where:

t1-line-number is 1-28.

brief displays a list of configurations only.

tabular displays a list of configurations and MIB data in a tabular format.

The following examples show command output display information for a PA-MC-2T3+ in port adapter slot 0 on a VIP installed in interface processor slot 1, using the following commands.


Note You can use these show controllers T3 commands in Cisco 7200 series, Cisco 7301 routers, and Cisco 7401ASR routers in which the PA-MC-2T3+ is supported. The syntax is as follows:

— show controllers T3 chassis-slot/t3-port/t1-line-number brief

— show controllers T3 chassis-slot/t3-port/t1-line-number tabular

— show controllers T3 chassis-slot/t3-port/t1-line-number remote performance

Examples of these show controllers T3 commands for Cisco 7200 series and Cisco 7401ASR routers are not shown.

Using the ping Command to Verify Network Connectivity

Using the ping command, you can verify that an interface port is functioning properly. This section provides a brief description of this command. Refer to the publications listed in the "Related Documentation" section on page viii for detailed command descriptions and examples.

The ping command sends echo request packets out to a remote device at an IP address that you specify. After sending an echo request, the system waits a specified time for the remote device to reply. Each echo reply is displayed as an exclamation point (!) on the console terminal; each request that is not returned before the specified timeout is displayed as a period (.). A series of exclamation points (!!!!!) indicates a good connection; a series of periods (.....) or the messages [timed out] or [failed] indicate a bad connection.

Following is an example of a successful ping command to a remote server with the address 10.0.0.10:

Router# ping 10.0.0.10 <Return>
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echoes to 10.0.0.10, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/15/64 ms
Router#

If the connection fails, verify that you have the correct IP address for the destination and that the device is active (powered on), and repeat the ping command.
