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
Restrictions

•VIP2
•More than 256 logical channel groups per PA-MC-STM-1
•Channel-associated signaling (CAS) for voice channels
•E1 Facility Data Link (FDL)

Determining Platform Support Through Cisco Feature Navigator
Cisco IOS software is packaged in feature sets that support 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 at 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.

Router(config-ctrlr-tug3)# tug-2 tug-2-number e1
e1-number loopback [local | network

Specifies a loopback for an E1 line.
•tug-2-number—A number in the range of 1 to 7.
•e1-number—A number in the range of 1 to 3.
•local—Loops transmitted E1 output back to the router via the internal E1 framer and loops E1 output to the network via the internal E1 framer.
•network—Loops E1 input back to the network.

Verifying the Configuration
You can verify the configuration and status of the controller by using the show controller commands as detailed below.
When AUG mapping is AU-4, view information about the SONET controller on a Cisco 7200 series router using the sonet controller sonet slot/port [brief | tabular] command. Use the sonet controller sonet slot/port-adapter/port [brief | tabular] command for a Cisco 7500 series router.
The following examples show sample output for a Cisco 7500 series router:

Configuration Examples
This section provides the following configuration examples:
•Configuring the PA-MC-STM-1 Example
•Configuring a Logical Channel Group on an E1 Line Example
•Configuring a Channel Group Interface Example
•Configuring an E1 Unframed Channel Example
Configuring the PA-MC-STM-1 Example
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
Configuring a Logical Channel Group on an E1 Line Example
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 1/0/0
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
Configuring a Channel Group Interface Example
Once a channel group has been created, interface serial configuration commands may be used as in the following example:
Router(config)# controller sonet 1/0/0
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 Example
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 following example:
Router(config)# controller sonet 1/0/0
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
Router(config-ctrlr-tug3)# mode c-12
