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 N*64 Kbps timeslots.

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 are input into virtual containers (VC) 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

Restrictions

The PA-MC-STM-1 does not support the following:

VIP2

More than 256 logical channel groups per PA-MC-STM-1

Channel-associated-signaling (CAS) for voice channels

E1 Facility Data Link (FDL)

E3 and subrate E3

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 1/1/0
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 timeslots 1 to 5 and 20 to 23 are assigned to the newly created logical channel group:

Router(config)# controller sonet 1/1/0
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 1/1/0
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

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/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:

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:

Router(config)# controller sonet 2/0/0
Router(config-controller)# aug mapping au-3
Router(config-ctrlr-au3)# au-3 3

Usage Guidelines

Use the tug-2 e1 unframed command in configuration controller tug3 command mode to create an unframed (clear channel) logical channel group on an E1 line that has been mapped to a TUG-3 via the aug-mapping au-4 command.

Use the tug-2 e1 unframed command in configuration controller au3 command mode to create an unframed (clear channel) logical channel group on an E1 line that has been mapped to an AU-3 via the aug-mapping au-3 command.

The channel group number for unframed E1 lines is always 0.

Examples

The following example configures an unframed logical channel group on E1 line 1, that has been mapped to a TUG-3:

Router(config)# controller sonet 2/0/0
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

The following example configures an unframed logical channel group on E1 line 1, that has been mapped to an AU-3:

Router(config)# controller sonet 2/0/0
Router(config-controller)# aug mapping au-3
Router(config-controller)# au-3 1
Router(config-ctrlr-au3)# tug-2 4 e1 1 unframed
