Continuing Configuration Using the Command-Line Interface

Note The information herein applies to the Cisco AS5350, Cisco AS5400, and Cisco AS5400HPX universal gateways. Note that the latter requires use of Cisco IOS release 12.2(2)XB or later.

This chapter continues where "Basic Configuration Using the Command-Line Interface" ends. After you have commissioned your Cisco AS5350 or Cisco AS5400 universal gateway, you might want to configure other features that include serial interface support, CT1 channel groups, and signaling.

Proceed to the following sections:

•Configuring Synchronous Serial Interfaces for WAN Support

•Configuring CT1 Channel Groups

•Configuring ISDN NFAS on CT1 PRI Groups

•Configuring E1 R2 Signaling

•Configuring Alarms

•Saving Configuration Changes

For advanced configuration topics and procedures, go to Configuring Selected 12.1 Cisco IOS Software Features, available online at
http://www.cisco.com/univercd/cc/td/doc/product/access/acs_serv/as5400/index.htm

You can also view these publications on the Documentation CD-ROM that arrived with your gateway.

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/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
Command

Purpose
Step 1
AS5350> enable
Password: password
AS5350# 
Enters enable mode (also called privileged EXEC mode) and enter the password. You are in enable mode when the prompt changes to AS5350# or AS5400#.
Step 2

•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 the network interface is properly connected and terminated.

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

Configuring CT1 Channel Groups

You can configure up to 24 channel groups for each CT1 for backup links or serial backhaul connections.

First, you must define the timeslots that belong with each channel group. Channel groups are numbered 0 to 23, and timeslots 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 CT1 controller can be arbitrarily assigned.

Configure

Perform the following task in controller configuration mode to define the channel groups and timeslots:
Command

Purpose
AS5350(config-controller)# channel-group 
number timeslots range [speed {48 | 56 | 
64}]
Defines the channel group number and, if needed, circuit speed.¹

Note Working with your local service provider, you can create channel-groups with from 1 to 24 timeslots. These timeslots can be in any order, contiguous or noncontiguous.
¹In the United States, channel-group speeds can be either 56 or 64 kbps; the default is 56 kbps. If 64 kbps is used, it is recommended to be used with framing type of ESF and a linecode of B8ZS. The speed you select must match the speed provided by the telephone company.
After you define the T1 channel groups, you can configure each channel group as a serial interface. Meaning, you can think of each channel group as a virtual serial interface. Subinterface configuration is also supported on the created serial interface.

Perform the following task in global configuration mode to enter interface configuration mode and configure the serial interface that corresponds to a channel group:
Command

Purpose
AS5350(config)# interface serial 
slot/port:channel-group
Defines the serial interface for a CT1 channel group.
Verify

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

Configuring ISDN NFAS on CT1 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 channelized T1 controllers configured for ISDN, you use an extended version of the ISDN pri-group command to specify the following:

•Range of PRI timeslots to be under the control of the D channel (timeslot 24)

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

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

Note Your Cisco AS5350 or Cisco AS5400 must connect to a Primary-4ess, Primary-DMS 100, or Primary-NI switch (see Table 3-3) 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 in 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 set 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 DNIS support turned on by default. If you enable the 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, the ANI number is assigned to gateway A. Also, note that ANI is similar to caller ID.

Configure

To configure E1 R2 signalling, 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 enter 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 controller dfc-slot, port number, and channel. On the CE1 trunk 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 timeslots 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 the ANI addr info 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 "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
controller E1 0 
 clock source line primary 
 ds0-group 0 timeslots 1-15,17-31 type

  category 2				  <--- default category for 
singapore 
  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 to 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}
Set the SPE country code or use 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 AS5350 and Cisco AS5400, 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)#
Enter voice port mode for the port you want to configure.
Step 10
AS5350(config-voiceport)# cptone 
contry-code
Enter the two-digit country code to configure the regional ring tone.
Step 11
AS5350(config-voiceport)# Ctrl-Z
AS5350#
Return to enable mode.

Tip If the connection does not go up, check for the following:

•Loose wires, splices, connectors, shorts, bridge taps, and grounds

•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

•CT1/CE1/CT3 controller down

•Trunk card failure

•Redundant power supply (RPS) failure

Cisco IOS software polls every second to detect the failure events that you have configured and turns on the 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.
AS5350# no facility-alarm detect rps
