Configuring the PA-MC-T3


To continue your PA-MC-T3 installation, you must configure the MC-T3 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

Configuring the Interfaces

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#


To configure the new interfaces, proceed to the "Configuring the Interfaces" section.

Configuring the Interfaces

After you verify that the new PA-MC-T3 is installed correctly (the ENABLED LED goes on), use the privileged-level configure command to configure the new interfaces. Have the following information available:

Protocols you plan to route on each new interface

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

Bridging protocols you plan to use

If you installed a new PA-MC-T3 or if you want to change the configuration of an existing T3 link, you must enter configuration mode to configure the new interfaces. If you replaced a PA-MC-T3 that was previously configured, the system recognizes the new T3 link and brings it up in its existing configuration.

For a summary of the configuration operations available and instructions for configuring interfaces on a PA-MC-T3, refer to the appropriate configuration publications listed in the "Related Documentation" section on page viii.

You execute configuration commands from the privileged-level access of the EXEC command interpreter. Contact your system administrator, if necessary, to obtain password access. (See the "Using the EXEC Command Interpreter" section for and explanation of the privileged level of the EXEC.)

This section contains the following subsections:

Configuring T1 Lines

Shutting Down an Interface

Performing a Basic Interface Configuration

Configuring the T3 Controller

Configuring T1 Lines

This section provides information about configuring T1 lines on the T3 link of the PA-MC-T3 and includes the following subsections:

T1 Line Configuration Commands

Configuring a BERT on a T1 Line

Sending a BERT Pattern on a T1 Line

Viewing the Results of a BERT

Terminating a BERT


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.

The PA-MC-T3 port addressing might be different depending on the interface processor slot in which the VIP is installed and the VIP port adapter slot in which the PA-MC-T3 is installed.


T1 Line Configuration Commands

You can create a logical channel group on a T1 line using the following controller commands as appropriate for your channelized configuration:

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

where:

t1-line-number is 1 to 28 (all 28 T1 lines can have more than one logical channel group).

channel-group channel-group-number defines a logical channel group with a range of 0 to 23 to be a channelized T1 line (T1 lines 1 to 28 can be channelized).

timeslots list-of-timeslots can be 1 to 24 or a combination of subranges within 1 to 24 (each subrange is a list of time slots that makes up 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.

Table 4-1 shows the configuration of logical channel group 20 on T1 line 1 assigning channelized time slots 1 to 5 and 20 to 23.

You can remove a logical channel group from a T1 line with the no-t1 controller command.

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

where:

t1-line-number is 1 to 28.

channel-group-number is 0 to 23.

Table 4-1 shows how to remove logical channel group 10 from channelized T1 line 1.

Table 4-1 T1 Line Configuration Commands 

Purpose
Command
Example
Additional Information

Create a logical channel group on a T1 line

t1 t1-line-number channel-group channel-group-number

The example is for interface 0 in port adapter slot 1.

Router(config)# controller 
t3 1/0
Router(config-controller)# 
t1 1 channel-group 20 
timeslots 1-5, 20-23
 

Remove a channel group from a T1 line

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

The example is for interface 0 on a port adapter in port adapter slot 1.

Router(config)# controller 
t3 1/0
Router(config-controller)# 
no t1 1 channel-group 10
 

Set the framing format on a T1 line

t1 t1-line-number framing {esf | sf}

The example sets Super Frame (SF) framing for T1 line 6.

Router(config)# controller 
t3 1/0
Router(config-controller)# 
t1 6 framing sf

Standard framing (SF)

Default framing format is Extended Superframe (ESF).

Turn detection or generation of a yellow alarm on and off

[no] t1 t1-line-number yellow {detection | generation}

The example turns the detection of a yellow alarm off on a T1 line 6.

Router (config-controller)
# no t1 6 yellow detection

When you select SF framing, consider turning off yellow alarm detection; yellow alarm can be incorrectly detected with SF framing.

Set the ESF framing format on a T1 line

t1 16 framing esf

The example sets ESF framing for T1 line 16.

Router(config)# controller 
t3 1/0
Router(config-controller)# 
t1 6 framing esf

Extended Superframe (ESF)

Set internal clock source on a T1 line

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

The example configures T1 line 1 to use an internal clock source on a VIP in interface processor slot 1.

Router(config)# controller 
t3 1/0/0
Router(config-controller) 
# t1 1 clock source 
internal

t1-line-numbers are 1 to 28.

The default clock source is internal.

You can set the clock source to use internal clocking for testing purposes. One end of a T1 circuit must provide the clock source.

Set line clock source on a T1 line

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

The example configures T1 line 16 using a line clock source on a VIP in interface processor slot 1.

Router(config)# controller 
t3 1/0/0
Router(config-controller)# 
t1 6 clock source line
 


Note After a T1 line is configured, it appears to the Cisco IOS software as a serial interface; therefore, all the configuration commands for a serial interface are available. However, not all commands apply to the T1 line. All the encapsulation formats, such as PPP, HDLC, SMDS, and Frame Relay are applicable to the configured T1 line. Encapsulation can be set using the serial interface configuration commands. All the switching types that are applicable to a serial interface, including optimum switching, are also applicable to the configured T1 line.


Configuring a BERT on a T1 Line

Bit error rate test (BERT) circuitry is built into the PA-MC-T3. Using BERT you can test cables and signal problems in the field. You can configure individual T1 lines to run an independent BERT; each T1 line has its own BERT circuitry.

Two categories of test patterns can be generated by the onboard BERT circuitry: pseudorandom and repetitive. The former test patterns are exponential 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 description of each type of test pattern follows:

Pseudorandom test patterns:

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

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

2^20-153 (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 14,440 minutes (240 hours), and you can also retrieve the error statistics anytime during the BERT.


Note BERT testing for the T3 link is not supported.


When running a BERT, your system expects to receive the same pattern that it is transmitting. To help ensure this, you can use one of two common options:

Use a loopback somewhere in the link or network.

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

Sending a BERT Pattern on a T1 Line

You can send a BERT pattern on a T1 line with the following command:

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

where:

t1-line-number is 1 to 28.

time is 1 to 14440 minutes.

pattern is:

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

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

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

2^15-0.151 pseudorandom 0.151 test pattern (32,768 bits long).

2^20-0.153, pseudorandom 0.153 test pattern (1,048,575 bits long).

2^20-QRSS, pseudorandom QRSS 0.151 test pattern (1,048,575 bits long).

2^23, pseudorandom 0.151 test pattern (8,388,607 bits long).

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


Note Use unframed T1 to run BERTs. If you do not specify unframed, the port adapter uses the currently configured T1 framing option to run a BERT.


Examples follow:

Send a BERT pseudorandom pattern of 2^20 through T1 line 10 for 5 minutes.

show controllers t3 slot/port-adapter/port/t1-line-number

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

You can view the results of a BERT 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 BERT 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 BERT 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.



Note The BERT runs over the currently configured framing option for the specified T1 line (ESF or SF). Before running a BERT, you should configure the framing option that is appropriate to your application. You can run the BERT unframed by specifying unframed.


Terminating a BERT

You can terminate a BERT with the following command:

no t1 t1-line-number bert

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

The following examples show how to terminate the BERT running on T1 line 10 in different platforms.

The example that follows is for a port adapter on a Catalyst RSM/VIP2 in slot 1:

Router(config)# controller t3 1/0
Router(config-controller)# no t1 10 bert

The example that follows is for a port adapter on a Catalyst 6000 family FlexWAN module in interface processor slot 5:

Router(config)# controller t3 5/0/0
Router(config-controller)# no t1 10 bert

The example that follows is for a port adapter in slot 1 of the Cisco 7200 series router, Cisco 7200 VXR router, Cisco uBR7200 series router, Cisco 7201 router, Cisco 7301 router, or a Cisco 7401ASR router:

Router(config)# controller t3 1/0
Router(config-controller)# no t1 10 bert

The example that follows is for a port adapter in slot 3 of of a Cisco 7304 PCI port carrier card of a Cisco 7304 router:

Router(config)# controller t3 3/0
Router(config-controller)# no t1 10 bert

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

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 and T3 controller configurations:

Shutting Down an Interface

Performing a Basic Interface Configuration

Configuring the T3 Controller

Shutting Down an Interface

Before you remove an interface that you will not replace or replace port adapters, use the shutdown command to shut down (disable) the interfaces to prevent anomalies when you reinstall the new or reconfigured interface processor. 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 "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)#

Step 3 Shut down interfaces by entering the interfaces serial subcommand (followed by the interface address of the interface), and then enter the shutdown command.

This step assumes you have already configured the logical channel group. For channelized T1 lines, channel-group-number can be 0 to 23.

When you have finished, 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.


Note If you need to shut down additional interfaces, enter the interface serial command (followed by the address of the interface) for each of the interfaces on your port adapter. Use the no shutdown command to enable the interface.

Step 6 Re-enable the interfaces by doing the following:

a. Repeat Step 3 to re-enable an interface. Substitute the no shutdown command for the shutdown command.

b. Repeat Step 4 to write the new configuration to memory. Use the copy running-config startup-config command

c. Repeat Step 5 to verify that the interfaces are in the correct state. Use the show interfaces command followed by the interface type and interface address of the interface.


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

Performing a Basic Interface Configuration

Following are instructions for a basic configuration, which include enabling an interface, specifying IP routing, and configuring the T3 controller. 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# configure 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 4-4 shows the interface serial command syntax for the supported platforms:

Table 4-4 Examples of the interface serial Subcommands for the Supported Platforms

The example is for logical channel group 1 on T1 line 1 of the T3 link on interface 0 on a port adapter in port adapter slot 1 of a VIP installed in interface processor slot 1.

Router(config-if)# interface serial 1/1/0/1:1
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 Re-enable the interfaces using the no shutdown command. (See the "Shutting Down an Interface" 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 interface 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.

Configuring the T3 Controller

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

T3 Controller Configuration Commands

Configuring MDL Messages

Configuring Idle Patterns

Configuring the Loopback Mode for the T3 Controller

Configuring the T3 Controller To Enable Remote Loopback

Shutting Down the T3 Controller

T3 Controller Configuration Commands

Table 4-5 summarizes T3 controller configuration commands.

Table 4-5 T3 Controller Configuration Commands 

Purpose
Command
Example
Additional Information

Select a T3 controller

controller t3 slot/port-adapter/port

The example shows a port adapter on a Cisco 7200 series router in port adapter slot 1.

Router# controller t3 1/0

You must enter this command before any other T3 configuration commands.

Set the framing type for a T3 controller

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

The example sets c-bit framing.

Router(config-controller)# 
framing c-bit

The example sets m23 framing.

Router(config-controller)# 
framing m23

You can request the PA-MC-T3 to detect the framing type it is to receive from the far end as follows:

router(config-controller)# 
framing auto-detect

Specify the cable length1

cablelength feet

The example sets cable length.

Router(config-controller)# 
cablelength 402 

Feet is a number from 0 to 450.

The default value is 49 feet.

Set the clock source for the T3 controller

clock source {internal | line}

The example instructs a PA-MC-T3 on a VIP in interface processor slot 1 to use a line clock source.

Router(config)# controller t3 
1/0/0
Router(config-controller)# clock 
source line

The example instructs a PA-MC-T3 on a Cisco 7200 series router to use an internal clock source.

Router(config)# controller t3 
1/0
Router(config-controller)# clock 
source internal
 

1 User-specified T3 cable lengths are structured into ranges as follows: 0-49 and 50-450. If you enter a cable length value that falls into one of these ranges, the range within which that applies is used.

2 Since a cable length of 40 is specified, the 0-49 range is used. If you change the cable length to 45, the 0-49 range still applies. Further, if you specify a cable length of 100 and then change it to 200, the 50-450 range applies in each case; therefore, these changes have no effect. 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.


Configuring MDL Messages

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


Note MDL messages are only supported when the T3 framing is set for c-bit parity. (See Table 4-5 for T3 controller configuration commands.)


To configure MDL messages, use the 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 the mdl command to remove MDL messages. The default is that no MDL message is configured.

Table 4-6 summarizes the MDL message configuration controller commands.

Table 4-6 MDL Message Configuration Commands 

Purpose
Command
Example

Enable the MDL path message transmission

Enter the unit identification code

mdl string unit abc
Router(config-controller)# mdl 
string unit abc

Enter the facility identification code to send in the MDL path message

mdl string pfi string
Router(config-controller)# mdl 
string pfi string

Enter the port number to send in the MDL idle signal message

mdl string port string
Router(config-controller)# mdl 
string port string

Enter the generator number to send in the MDL test signal message

mdl string generator string
Router(config-controller)# mdl 
string generator string

Configuring Idle Patterns

You can set a specific pattern to be transmitted for unused time slots on all T1 lines. Unused time slots are time slots that have not been assigned to any logical channel group on channelized T1 lines. To set an idle pattern, use the controller command:

idle pattern patterns

where:

patterns is a hexadecimal number in the range of 0x0 to 0xFF (hexadecimal) or 0 to 255 (decimal); you can enter this value in either hexadecimal or decimal.

The default idle pattern is 0x7F (or 127).

Table 4-7 shows the hexadecimal l idle pattern controller command syntax for the supported platforms.

Configuring the Loopback Mode for the T3 Controller

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 condition, use the no form of the command:

no loopback

Local loopback simultaneously loops all channels toward the router and loops the T3 link back toward the network. You can use local loopback to diagnose problems with cables between the T3 controller and the central switching office at the T3 link level.

3 Remote loopbacks are only available when you use c-bit parity framing.

4 Remote loopbacks are only available when you use c-bit parity framing.


Configuring the T3 Controller To Enable Remote Loopback

You can configure whether or not the port adapter responds to remote T3 loopback and T1 loopback requests it receives from the remote site using the controller command:

equipment [customer | network] loopback

You can configure the port adapter to respond to remote T3 loopback and T1 loopback requests it receives from the remote site using the equipment customer loopback command; you can configure the port adapter to ignore remote T3 and T1 loopback commands using the equipment network loopback command.

Shutting Down the T3 Controller

You can shut down the T3 controller on the PA-MC-T3 using the shutdown controller command.

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

Enabling Performance Reports

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 to 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.


Displaying Remote Performance Reports

To display remote (far-end) performance data, use the following command:

show controllers t3 1/0/0/1 remote performance.

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 requests 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 that a bad connection.

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

Router# ping 10.0.0.10
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echoes to 1.1.1.10, 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.

Proceed to the next section, "Using loopback Commands (t1)," to finish checking network connectivity.

Using loopback Commands (t1)

With the loopback test, you can detect and isolate equipment malfunctions by testing the connection between the PA-MC-T3 interface and a remote device such as a modem or a CSU/DSU. 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 or compact serial cable. If the packets complete the loop, the connection is good. If not, you can isolate a fault to the remote device or compact serial cable in the path of the loopback test.


Note You must configure a clock rate on the port before performing a loopback test. However, if no cable is attached to the port, the port is administratively up, and the port is in loopback mode; you do not have to configure a clock rate on the port before performing a loopback test.


Specify loopback for a T1 line using the following command:

t1 t1-line-number loopback [local | network {line | payload} | remote {line {fdl {ansi | bellcore} | inband} | payload [fdl] [ansi]}]

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


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


Explanations of specific loopback modes are as follows:

local

(Optional.) 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}

(Optional.) 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}

(Optional.) 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 bit 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

(Optional.) 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]

(Optional.) 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 bit loopback on the T1 channel.

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