Configuring Clear Channel T3/E3 and

Channelized T3 and T1/E1 Controllers on the

Cisco ASR 9000 Series Router

This module describes the configuration of clear channel T3/E3 controllers and channelized T3 and

T1/E1 controllers on the Cisco ASR 9000 Series Aggregation Services Routers.

You must configure the T3/E3 controller before you can configure an associated serial interface.

Feature History for Configuring T3/E3 Controller Interfaces

Release Modification

Release 3.9.0 This feature was introduced on the Cisco ASR 9000 Series Router for the

Cisco 2-Port Channelized OC-12c/DS0 SPA.

Release 4.0.0 Support for the following features was added on the Cisco 2-Port

Channelized OC-12c/DS0 SPA:

•NxDS0 channelization

•Link Noise Monitoring

Support for clear channel T3 controllers on the 1-Port Channelized

OC-48/STM-16 SPA was introduced.

Release 4.0.1 Support for the following SPAs was added:

•Cisco 1-Port Channelized OC-3/STM-1 SPA

•Cisco 2-Port and 4-Port Clear Channel T3/E3 SPA

Release 4.1.0 •Support for the following SPAs was added:

–

–

Cisco 8-Port Channelized T1/E1 SPA

•Support for a Link Noise Monitoring enhancement was added on the

Cisco 2-Port Channelized OC-12c/DS0 SPA to set thresholds for noise

errors on T1/E1 links that are used to signal the Noise Attribute to PPP

for removal of an MLPPP bundle link.

Prerequisites for Configuring T3/E3 Controllers

You must be in a user group associated with a task group that includes the proper task IDs. The command

reference guides include the task IDs required for each command. If you suspect user group assignment

is preventing you from using a command, contact your AAA administrator for assistance.

Before configuring T3/E3 controllers, be sure that you have one of the following supported SPAs

installed in the router:

•Cisco 2-Port and 4-Port Clear Channel T3/E3 SPA

•Cisco 4-Port Channelized T3/DS0 SPA

Note The 4-Port Channelized T3/DS0 SPA can run in clear channel mode, or it can be channelized

into 28 T1 or 21 E1 controllers.

•Cisco 1-Port Channelized OC-3/STM-1 SPA

•Cisco 2-Port Channelized OC-12c/DS0 SPA

•Cisco 1-Port Channelized OC-48/STM-16 SPA

•Cisco 8-Port Channelized T1/E1 SPA

•Before you can configure a clear channel T3 controller on the channelized SONET SPAs, you must

configure the SPA for an STS stream channelized for T3. For more information, see the

“Configuring Channelized SONET/SDH on the Cisco ASR 9000 Series Router” module.

Information About T3/E3 Controllers and Serial Interfaces

The 2-Port and 4-Port Clear Channel T3/E3 SPAs support clear channel services over serial lines only.

The 4-Port Channelized T3/DS0 SPA supports clear channel services and channelized serial lines. If a

controller is not channelized, then it is a clear channel controller, and the full bandwidth of its associated

serial line is dedicated to a single channel that carries serial services.

When a T3 controller is channelized, it is logically divided into smaller bandwidth T1 or E1 controllers,

depending on which mode of channelization you select. The sum of the bandwidth of the serial interfaces

on the T1 or E1 controllers cannot exceed the bandwidth of the T3 controller that contains those

channelized T1 or E1 controllers.

When you channelize a T3 controller, each individual T1 or E1 controller is automatically further

channelized into DS0 time slots. A single T1 controller carries 24 DS0 time slots, and a single E1

controller carries 31 DS0 time slots. Users can divide these DS0 time slots up into individual channel

groups. Each channel group can support a single serial interface.

OL-32684-01

When a controller is channelized, and channel groups have been created, services are provisioned on the

associated serial interfaces.

The channelization feature in this release allows the following types of channelization:

•A single T3 controller into 28 T1 controllers, for a total controller size of 44210 kbps.

•A single T3 controller into 21 E1 controllers, for a total controller size of 43008 kbps.

•A single T1 controller supports up to 1.536 MB.

•A single E1 controller supports up to 2.048 MB.

Note A single shared port adapter (SPA) can support up to 448 channel groups.

Configuration Overview

Configuring a channelized T3 controller and its associated serial interfaces is a 4-step process:

Step 1 Configure the T3 controller, and set the mode for that controller to T1 or E1.

Step 2 Configure the T1 or E1 controller.

Step 3 Create channel groups and assign DS0 time slots to these channel groups as desired.

Step 4 Configure the serial interfaces that are associated with the individual channel groups, as described in the

Configuring Serial Interfaces on the Cisco ASR 9000 Series Router module later in this document.

Default Configuration Values for T3 and E3 Controllers

Table 2 describes the default configuration parameters that are present on the T3 and E3 controllers.

Note • Auto-detect framing is not supported on the 2-Port Channelized OC-12c/DS0 SPA.

•E3 is not supported on the 4-Port Channelized T3/DS0 SPA.

Note When configuring clocking on a serial link, you must configure one end to be internal, and the other

end to be line. If you configure internal clocking on both ends of a connection, framing slips occur. If

you configure line clocking on both ends of a connection, the line does not come up.

Note When configuring clocking on a serial link, you must configure one end to be internal, and the other

you configure line clocking on both ends of a connection, the line does not come up.

Link Noise Monitoring on T1 or E1 Links

Link Noise Monitoring (LNM) provides the ability to monitor Path Code Violation (PCV) errors on T1

and E1 links on the 2-Port Channelized OC-12c/DS0 SPA on the Cisco ASR 9000 Series Router, and to

signal events and alarms on these links when noise continuously meets or exceeds configured thresholds

(the set threshold values) for those errors. Events are also signaled when noise falls below configured

improved thresholds (the clear threshold values).

Beginning in Cisco IOS XR Release 4.1, the LNM feature supports the lnm remove command to signal

the Noise Attribute to PPP to remove an MLPPP bundle member link when specified thresholds are

crossed.

Note An LCV is an occurrence of either a Bi-Polar Violation (BPV) or Excessive Zeroes (EXZ) error, and a

PCV is an occurrence of a CRC error in a timeslot. However, the LNM feature currently only monitors

PCV errors. The LCV values are only used to calculate an expected PCV if the PCV values are not

specified. If the PCV values are specified, then the LCV values are ignored.

LNM Events

There are two basic types of monitoring events produced by LNM:

•Crossed events—A crossed event signals when PCV threshold values continuously meet or exceed

the specified set values for major and minor warnings for a specified period of time (duration).

When a crossed event occurs, the major or minor monitoring type for the controller is reported as

the alarm state. When the crossed event is no longer present, the monitoring type returns to the

stable state.

The following are examples of crossed events:

RP/0/RSP0/CPU0:Router#0/1/CPU0:May 13 9:54:10.980 : g_spa_1[181]:

%L2-T1E1_LNM-3-MINWARNNOISE :

Interface T10/1/1/0/1/1/1, noise crossed minor warning threshold

RP/0/RSP0/CPU0:Router#0/1/CPU0:May 13 9:54:11.980 : g_spa_1[181]:

%L2-T1E1_LNM-3-MAJWARNNOISE :

Interface T10/1/1/0/1/1/1, noise crossed major warning threshold

•Cleared events—A cleared event signals when threshold values that were crossed have fallen below

the specified clear values for major and minor warnings.

The following are examples of cleared events:

RP/0/RSP0/CPU0:Router#LC/0/1/CPU0:May 13 10:27:25.809 : g_spa_1[181]:

%L2-T1E1_LNM-3-MAJWARNNOISE :

Interface T10/1/1/0/1/1/1, noise cleared major warning threshold

RP/0/RSP0/CPU0:Router#LC/0/1/CPU0:May 13 10:28:14.810 : g_spa_1[181]:

%L2-T1E1_LNM-3-MINWARNNOISE :

Interface T10/1/1/0/1/1/1, noise cleared minor warning threshold
