Multichannel STM-1 Port Adapter

Feature History

12.0(14)S

This feature was introduced for the Cisco 7500 series on Cisco IOS Release 12.0(14)S.

12.1(7)E

This feature was integrated into Cisco IOS Release 12.1(7)E. Support for this feature was added to Cisco 7200 VXR routers and Catalyst 6000 family switches.

12.2(14)S

This feature was integrated into Cisco IOS Release 12.2(14)S. Support for this feature was added to Cisco 7401 ASR routers.

This feature module describes the multichannel STM-1 port adapter (PA-MC-STM-1) in Cisco IOS Release 12.1(7)E. It includes information on the benefits of this port adapter, supported platforms, related documents, configuration examples and a command reference detailing new and enhanced commands.

Feature Overview

The PA-MC-STM-1 is a high-speed, single-port multichannel STM-1 port adapter. You can configure the PA-MC-STM-1 as a multichannel E1/E0 STM-1 port. The PA-MC-STM-1 can be configured into 63 individual E1 links. Each E1 link can carry a single channel at full or fractional rates, or be broken down into multiple DS0 or Nx64 Kbps rates. The PA-MC-STM-1 supports up to three TUG-3/AU-3 transport slots numbered 1 through 3. You can configure each TUG-3/AU-3 to carry 21 SDH TU-12s. Each SDH TU-12 is capable of carrying a channelized E1 frame, which can be unchannelized to nx64-Kbps time slots.

PA-MC-STM-1 Multiplexing Hierarchy

Figure 1 illustrates the synchronous digital hierarchy (SDH) multiplexing structure supported on the PA-MC-STM-1. The PA-MC-STM-1 multiplexing structure is a subset of that defined in ITU-T G.707. At the lowest level, containers (Cs) are input into virtual containers (VCs) with stuffing bits to create a uniform VC payload with a common bit-rate, ready for synchronous multiplexing. The VCs are then aligned into tributary units (TUs) where pointer processing operations are implemented. This allows the TUs to be multiplexed into TU groups (TUGs). Three TU-12s can be multiplexed into one TUG-2.

Figure 1 PA-STM-1 Multiplexing Structure

The TUGs are then multiplexed into higher-level VCs, which in turn are multiplexed into administrative units (AUs).The AUs are then multiplexed into an AU group (AUG), and the final payload from the AUG is then multiplexed into the Synchronous Transport Module (STM).

Benefits

The PA-MC-STM-1 port adapter provides the following benefits:

•High-density IP aggregation

•Reduction in provisioning costs

•Improved cable management

•Easier scaling of services

•Improved network availability

Determining Platform Support Through Cisco Feature Navigator

Cisco IOS software is packaged in feature sets that are supported on specific platforms. To get updated information regarding platform support for this feature, access Cisco Feature Navigator. Cisco Feature Navigator dynamically updates the list of supported platforms as new platform support is added for the feature.

Cisco Feature Navigator is a web-based tool that enables you to determine which Cisco IOS software images support a specific set of features and which features are supported in a specific Cisco IOS image. You can search by feature or release. Under the release section, you can compare releases side by side to display both the features unique to each software release and the features in common.

To access Cisco Feature Navigator, you must have an account on Cisco.com. If you have forgotten or lost your account information, send a blank e-mail to cco-locksmith@cisco.com. An automatic check will verify that your e-mail address is registered with Cisco.com. If the check is successful, account details with a new random password will be e-mailed to you. Qualified users can establish an account on Cisco.com by following the directions found at this URL:

http://www.cisco.com/register

Cisco Feature Navigator is updated regularly when major Cisco IOS software releases and technology releases occur. For the most current information, go to the Cisco Feature Navigator home page at the following URL:

http://www.cisco.com/go/fn

Availability of Cisco IOS Software Images

Platform support for particular Cisco IOS software releases is dependent on the availability of the software images for those platforms. Software images for some platforms may be deferred, delayed, or changed without prior notice. For updated information about platform support and availability of software images for each Cisco IOS software release, refer to the online release notes or, if supported, Cisco Feature Navigator.

Configuration Examples

This section provides the following configuration examples:

•Configuring the PA-MC-STM-1

•Configuring a Logical Channel Group on an E1 Line

•Configuring a Channel Group Interface

•Configuring an E1 Unframed Channel

Configuring the PA-MC-STM-1

You can configure each of the AUGs and TUGs of a PA-MC-STM-1 to carry a set of E1 links that are mapped into tributary unit level-12s (TU-12s).

In the following example, SDH framing, internal clock source, AUG mapping au-4 and idle pattern are configured:
Router(config)# controller sonet 1/0
Router(config-controller)# framing sdh
Router(config-controller)# clock source internal
Router(config-controller)# aug mapping au-4
Router(config-controller)# au-4 1 tug-3 2
Router(config-ctrlr-tug3)# mode c-12
Router(config-ctrlr-tug3)# tug-2 4 e1 channel-group 15 timeslots 1-5, 20-23
Router(config-ctrlr-tug3)# idle pattern 0x0
Router(config-ctrlr-tug3)# exit
Router(config-controller)#
Configuring a Logical Channel Group on an E1 Line

To configure a logical channel group on an E1 line, use the tug-2 tug-2-number e1 e1-number channel-group channel-group-number timeslots list-of-timeslots command. In the following example, logical channel group 15 on E1 line 1 is configured and channelized time slots 1 to 5 and 20 to 23 are assigned to the newly created logical channel group:
Router(config)# controller sonet 1/0
Router(config-controller)# framing sdh
Router(config-controller)# aug mapping au-4
Router(config-controller)# au-4 1 tug-3 2
Router(config-ctrlr-tug3)# mode c-12
Router(config-ctrlr-tug3)# tug-2 4 e1 1 channel-group 15 timeslots 1-5, 20-23
Router(config-ctrlr-tug3)# exit
Router(config-controller)# exit
Configuring a Channel Group Interface

Once a channel group has been created, interface serial configuration commands may be used as in the example below:
Router(config)# controller sonet 1/0
Router(config-controller)# framing sdh
Router(config-controller)# aug mapping au-4
Router(config-controller)# au-4 1 tug-3 2
Router(config-ctrlr-tug3)# mode c-12
Router(config-ctrlr-tug3)# tug-2 4 e1 10 channel-group 15 timeslots 1-5, 20-23
Router(config-ctrlr-tug3)# exit
Router(config-controller)# exit
Router(config)# interface serial 1/1/0.1/2/4/1:15
Router(config-if)# ip address 1.1.1.10 255.255.255.252
Router(config-if)# encapsulation ppp
Configuring an E1 Unframed Channel

To create an unframed or clear channel logical channel group on an E1 line, use the tug-2 tug-2-number e1 e1-number unframed command, as shown in the example below:
Router(config)# controller sonet 1/0
Router(config-controller)# aug mapping au-4
Router(config-controller)# au-4 1 tug-3 2
Router(config-ctrlr-tug3)# tug-2 4 e1 1 unframed
Router(config-ctrlr-tug3)# mode c-12

12.2(14)S

This command was integrated into Cisco IOS Release 12.2(14)S.

Usage Guidelines

An AUG of an STM-1 can be derived from either AU-3s or an AU-4. Use the aug mapping au-3 configuration controller command to map the AUG to an AU-3 with the following muxing, alignment, and mapping:

C-12 <--> VC-12 <--> TU-12 <--> TUG-2 <--> VC-3 <--> AU-3 <--> AUG

Configuring the au-3 command enables you to enter configuration controller au3 command mode and creates a serial interface with the following name format for Cisco 7200 VXR routers and Catalyst 6000 family switches:

slot/port.au-3-number/tug-2-number/e1-number

Configuring the au-3 command enables you to enter configuration controller au3 command mode and creates a serial interface with the following name format for Cisco 7500 series routers:

slot/port-adapter/port.au-3-number/tug-2-number/e1-number

The aug mapping au-3 and au-3 commands are available only when SDH framing is configured.

Examples

The following example configures AUG mapping to be derived from an AU-3 and selects AU-3 3 to configure as a serial interface on a Cisco 7500 series router:
Router(config)# controller sonet 2/0/0

Configuring the au-4 command enables you to enter configuration controller tug3 command mode and creates a serial interface with the following name format for Cisco 7200 VXR routers or Catalyst 6000 family switches:

slot/port.au-4-number/tug-2-number/e1-number

Configuring the au-4 command enables you to enter configuration controller tug3 command mode and creates a serial interface with the following name format for Cisco 7500 series routers:
