Channelized T3 Support for the Cisco  AS5800

Feature Summary

The Channelized T3 (CT3) Interface Processor and Port Adapter are available on Cisco AS5800 access servers. This card provides for the aggregation of channelized interfaces into a single T3 facility. T3 support on the Cisco AS5800 allows support for 28 T1s (672 channels) per chassis.

Benefits

Channelized T3 allows for increased port density and lower cost per port, and supports a standard, widely-available, North American service. Channelized T3 (CT3) support will allow users to get the maximum benefit of double-density modem technology in the Cisco AS5800.

List of Terms

The following terms, in alphabetical order appear in this feature documentation:

DS1---The Digital Signal level for T1-class channels.

DS3---The Digital Signal level for T3-class channels.

T1---A North American standard T-Carrier, multiplexed system for channels.

T3---A North American standard T-Carrier, multiplexed system for channels.

Platforms

This feature is supported on the Cisco AS5800.

Supported MIBs and RFCs

None

Configuration Tasks

Table 1 lists commands to help you configure your CT3 card.


Note The "/" symbol is used in commands to specify a physical location. Thus 1/0/0 on a T3 port tells you where you can plug something into the Cisco AS5800. The ":" symbol is used in commands to specify a time-multiplexed division within a physical port.

Table 1:
Step Command1 Purpose

1 . 

AS5800-1>  enable
Password: password
AS5800-1#  

Enter the enable command.
Enter your password.
You are in privileged EXEC mode when the prompt changes to AS5800-1#. (The host name AS5800-1 used in this example was assigned via the hostname command.)

2 . 

AS5800-1#  configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
AS5800-1(config)#

Enter global configuration mode by entering the configure command. The example is using the terminal configuration option.

You are in global configuration mode when the prompt changes to AS5800-1(config)#.

3 . 

AS5800-1(config)#  controller t3 shelf/slot/0

Enter controller configuration mode to configure your T3 controller in the specified shelf, slot, and port. 0 is the only legal port value.

4 . 

AS5800-1(config-controller)# description ascii-string

Enter an optional text description for the T3 controller.

5 . 

AS5800-1(config-controller)#  
cablelength 450

Enter the controller cablelength value between 0 and 450 (feet).

6 . 

AS5800-1(config-controller)#  
framing {c-bit  |  m23}

Enter the type of T3 framing used. C-bit specifies C-bit parity framing. M23 (default) specifies M23 multiplexer framing.

7 . 

AS5800-1(config-controller)#  t1 ds1 controller

Create a logical T1 controller from each of the specified T3 line timeslots. DS1 is a T1 timeslot within the T3 line with a value between 1 and 28. (The T1 controller will be in shelf/slot/0:ds1.

8 . 

AS5800-1(config-controller)#  exit

Exit controller configuration mode and return to global configuration mode.

9 . 

AS5800-1(config)#  controller t1 shelf/slot/port:t1-num

Enter controller configuration mode to configure your T3 controller port. t1-num is a T1 timeslot within the T3 line with a value between 1 and 28.

10 . 

AS5800-1(config-controller)#  exit

Exit controller configuration mode and return to global configuration mode.

11 . 

AS5800-1(config)#  dial-tdm-clock priority {1-50} {external  |  trunk-slot 0-5} ds3-port  0  port {1-28}

Configure clock priority, which is a value between 1 and 50.

Select a clocking source by selecting the external reference clock or any port of a trunk card. If you are using the external reference clock, no other CLI is needed. If you are using a trunk card, select a dial shelf slot between 0 and 5.

Select the T3 port number, which has a value of 0. Possible T1 port values are 1 to 28.

12 . 

AS5800-1(config)#  CNTL/Z

Exit global configuration mode and return to EXEC mode.

13 . 

AS5800-1#  copy running-config startup-config

Save your changes when ready.

1To deactivate a command functionality, type no before the command.

Related Commands

clear interface serial

t1

To create a logical T1 controller from each of the specified timeslots of the T3 line, enter the t1 controller configuration command. Enter the no form of this command to delete the defined logical controller.

t1 ds1 controller
no t1
ds1 controller
Syntax Description

ds1

A timeslot within the T3 line. The valid timeslot range is from 1 to 28.

Default

None.

Command Mode

Controller configuration

Usage Guidelines

This command first appeared in Cisco IOS Release 11.3(5)AA.

The purpose of this command is to convert the collection of the 28 T1 controllers that comprise the T3 controller into individual T1 controllers that the system can use. In other words, the Cisco  AS5800 cannot pass data until a T1 controller is configured (using the controller t1 command), and you can't configure a T1 controller until it has been created using the t1 command.

Example

The following example configures a logical T1 controller at T1 timeslot 1 for the T3 controller located in shelf 1, slot 4, port 0. Note that you have to issue the command from the controller configuration mode.

AS5800-1(config)# controller t3 1/4/0
AS5800-1(config-controller)# t1 1 controller
AS5800-1(config-controller)# end
AS5800-1#
