Continuing Configuration Using the Command-Line Interface

The information in this chapter applies to the Cisco AS5350XM and Cisco AS5400XM universal gateways. This chapter continues where the "Basic Configuration Using the Command-Line Interface" chapter ends. After you have commissioned your Cisco AS5350XM or Cisco AS5400XM universal gateway, you might want to configure other features that include serial interface support, T1 channel groups, and signaling.

Proceed to the following sections:

•Configuring Synchronous Serial Interfaces for WAN Support

•Configuring T1 Channel Groups

•Configuring ISDN NFAS on Channelized T1 PRI Groups

•Configuring E1 R2 Signaling

•Configuring Alarms

•Saving Configuration Changes

•Where to Go Next

Tip If you are experienced using the Cisco IOS software, you might find the "Where to Go Next" section at the end of this chapter a useful reference for configuration.

Configuring Synchronous Serial Interfaces for WAN Support

Configure the synchronous serial interfaces on the motherboard to connect to a WAN through a CSU or DSU.

This section describes how to enable the serial interface, specify IP routing, and set up external clock timing on a DCE or DTE interface. To use a port as a DTE interface, you need only connect a DTE adapter cable to the port. When the system detects the DTE mode cable, it automatically uses the external timing signal. To use a port in DCE mode, you must connect a DCE interface cable and set the clock speed with the clock rate configuration command. You must also set the clock rate to perform a loopback test.

Configure

•Display the entire system configuration file with the show configuration command. Verify that the configuration is accurate for the system and each interface.

Tip If you are having trouble, make sure that the network interface is properly connected and terminated.

Note If you have questions or need assistance, see the "Obtaining Documentation" section on page 21.

Configuring T1 Channel Groups

You can configure up to 24 channel groups for each T1 controller for backup links or serial backhaul connections.

First, you must define the time slots that belong with each channel group. Channel groups are numbered 0 to 23, and time slots are numbered 1 to 24. Defining a channel group creates a serial interface; defining multiple channel groups creates an equal number of serial interfaces that you can configure independently.

Note The channel group numbers for each channelized T1 controller can be arbitrarily assigned.

Configure

To define the channel groups, time slots, and (if needed) circuit speed, enter the following command in controller configuration mode:
AS5350(config-controller)# channel-group number timeslots range [speed {48 | 56 | 64}]
In the United States, channel-group speeds can be either 56 or 64 kbps. If 64 kbps is used, we recommend that you use the ESF framing type and a linecode of B8ZS. Working with your local service provider, you can create channel groups with from 1 to 24 time slots. These time slots can be in any order, contiguous or noncontiguous.

After you define the T1 channel groups, you can configure each channel group as a serial interface (think of each channel group as a virtual serial interface). Subinterface configuration is also supported on the created serial interface.

To define the serial interface that corresponds to a T1 channel group, enter the following command in global configuration mode to enter interface configuration mode:
AS5350(config)# interface serial slot/port:channel-group
Verify

The following example shows a T1 controller configured for channel groups and an ISDN PRI group. The pri-group command and the channel-group command cannot have overlapping time slots; note the correct time slot configuration.

Configuring ISDN NFAS on Channelized T1 PRI Groups

ISDN Non-Facility Associated Signaling (NFAS) allows a single D channel to control multiple PRI interfaces. A backup D channel can also be configured for use when the primary NFAS D channel fails.

When configuring NFAS for T1 controllers configured for ISDN, you use an extended version of the ISDN pri-group command to specify the following:

•Range of PRI time slots to be under the control of the D channel (time slot 24)

•Function to be performed by time slot 24 (primary D channel, backup, or none); the last specifies its use as a B channel

•Group identifier number for the interface under control of this D channel

Note Your Cisco AS5350XM or Cisco AS5400XM universal gateway must connect to a Primary-4ESS, Primary-DMS 100, or Primary-NI switch (see Table 5 on page 15) and must also have a channelized T1 controller and, as a result, be ISDN PRI capable.

Configure

To configure ISDN NFAS, complete the following tasks in controller configuration mode:
Command

Purpose
AS5350(config-controller)# pri-group 
timeslots 1-24 nfas_d primary 
nfas_interface number nfas_group number
On one channelized T1 controller, configures the NFAS primary D channel.
AS5350(config-controller)# pri-group 
timeslots 1-24 nfas_d backup nfas_interface 
number nfas_group number
On a different channelized T1 controller, configures the NFAS backup D channel to be used if the primary D channel fails.
AS5350(config-controller)# pri-group 
timeslots 1-24 nfas_d none nfas_interface 
number nfas_group number
(Optional) On other channelized T1 controllers, configures a 24 B channel interface, if desired.
Take a Channel or Interface Out of Service

You can take a specified channel or an entire PRI interface out of service or put it into one of the other states that is passed on to the switch.

To do so, complete one of the following tasks in interface configuration mode:
Command

Purpose
AS5350(config-controller)# isdn service dsl 
number b_channel number state state-value
Takes an individual B channel out of service or sets it to a different state.
AS5350(config-controller)# isdn service dsl 
number b_channel 0 state state-value
Sets the entire PRI interface to the specified state.
These are the supported state values:

•0—In service

•1—Maintenance

•2—Out of service

Verify

Monitor NFAS groups by entering the show isdn nfas group number command:
AS5350# show isdn nfas group 0
ISDN NFAS GROUP 0x0 ENTRIES:
The primary D is Serial0:23.
The backup D is Serial1:23.
There are 2 total nfas members.
There are 24 total available B channels.
The primary D-channel is DSL 0 in state IN SERVICE.
The backup D-channel is DSL 1 in state STANDBY.
The current active layer 2 DSL is 0.
Configuring E1 R2 Signaling

R2 signaling is an international signaling standard that is common to channelized E1 networks. You can configure a channelized E1 interface to support different types of R2 signaling, used in older analog telephone networks.

Note The Cisco implementation of R2 signaling has dialed number identification support (DNIS) turned on by default. If you enable the automatic number identification (ANI) option, the collection of DNIS information is still performed. Specifying the ANI option does not disable DNIS collection. DNIS is the number being called. ANI is the caller's number. For example, if you are configuring gateway A to call gateway B, then the DNIS number is assigned to gateway B, and the ANI number is assigned to gateway A. Also, note that ANI is similar to caller ID.

Configure

To configure E1 R2 signaling, use the following commands, beginning in global configuration mode:
Command

Purpose
Step 1
AS5350> enable
Password: password
AS5350# 
Enters enable mode (also called privileged EXEC mode) and enters the password. You are in enable mode when the prompt changes to AS5350# or AS5400#.
Step 2
AS5350# configure terminal
Enter configuration commands, one per line. 
End with CNTL/Z.
AS5350(config)#
Enters global configuration mode. You are in global configuration mode when the prompt changes to AS5350(config)# or AS5400(config)#.
Step 3
AS5350(config)# controller e1 0/0
AS5350(config-controller)#
Enters controller configuration mode to configure your E1 controller port.

Specifies E1 feature card slot, port number, and channel. On the E1 feature card, port number values range from 0 to 1.
Step 4
AS5350(config-controller)# ds0-group 1 
timeslots 1-30 type r2-analog r2-compelled 
ani
Configures the time slots that belong to each E1 circuit for R2 signaling. Sets R2 signaling to R2 ITU Q411, the tone signal to R2 compelled register signaling, and ANI to address information provisioned option.

R2 line signaling options include r2-analog, r2-digital, and r2-pulse.

Tone signaling options include dtmf (default), r2-compelled, r2-non-compelled, and r2-semi-compelled.

You can also set ani (ANI address information provisioned) for any of the above options.
Step 5
AS5350(config-controller-cas)# cas-custom 1
Enters the channel number to customize.
Step 6
AS5350(config-ctrl-cas)# country country 
use-default
Uses defaults for the specified country.

Note To view the parameters for the country (if the country defaults are the same as ITU defaults), enter write term.

The default setting for all countries is ITU.

See the "Country Codes for R2 Signaling" section for a list of supported countries.
Step 7
AS5350(config-ctrl-cas)# answer-signal 
group-b 6
[or]
AS5350(config-ctrl-cas)# default 
answer-signal group-b 6
[or]
AS5350(config-ctrl-cas)# no answer-signal 
group-b 6

  answer-signal group-b 6				   <--- default 
bxfree 
  for singapore
AS5350(config-ctrl-cas)# exit
AS5350(config)#
Sets the cas custom command answer signal to group-b 6.

CAS custom commands include caller-digits, category, country, unused-abcd, invert-abcd, metering, ka, kd, dnis-digits, answer-signal, and nc-congestion

Sets answer-signal group-b to the default ITU value.

Resets answer-signal group-b 6 to the default value.

Note The parameters you do not set are automatically set to the ITU default by the gateway.

After you configure a country with default settings, the gateway displays a write term, similar to the one displayed here.

Exits CAS custom mode and returns to global configuration mode.
Step 8
AS5350(config)# spe country {country | 
e1-default}
Sets the SPE country code or uses the E1 default (A-law).

Note The gateway must be in idle state (no calls are active) to execute the SPE country command.

Note On the Cisco AS5350XM and Cisco AS5400XM universal gateway, DS-0 companding law selection is configured for the entire system rather than on individual voice ports.
Step 9
AS5350(config)# voice-port 
slot/controller-number:DS0 group-number
AS5350(config-voiceport)#
Enters voice port mode for the port you want to configure.
Step 10
AS5350(config-voiceport)# cptone 
contry-code
Enters the 2-digit country code to configure the regional ring tone.
Step 11
AS5350(config-voiceport)# Ctrl-Z
AS5350#
Returns to enable mode.

•Backwards transmit and receive

•Mismatched framing types (for example, CRC-4 and no-CRC-4)

•Transmit and receive pair separation (crosstalk)

•Faulty line cards or repeaters

•Noisy lines (for example, power and crosstalk)

If you see errors on the line or the line is going up and down, check for the following:

•Mismatched line codes (HDB3 versus AMI)

•Receive level

•Frame slips because of poor clocking plan

When the E1 controller comes up, you see the following message:
%CONTROLLER-3-UPDOWN: Controller E1 0, changed state to up
Configuring Alarms

Facility alarms currently monitor the following failure events:

•Interface down

•T1, E1, or T3 controller down

•Modem board failure

•Redundant power supply (RPS) failure

•Thermal failure

•Fan failure

Cisco IOS software polls every second to detect the failure events that you have configured and turns on an alarm when any one of the failure events is detected. By default, the facility alarm is off. Users have to configure a facility alarm command to enable monitoring of the failure conditions.

Enter no before the full command to disable any of the alarm commands.
