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.

Feature Overview

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.

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).

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

Multichannel STM-1 Port Adapter for the Cisco 7500 Series Router

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

Configuration Examples

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
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

Command Reference

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 1/1/0
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

au-3

To configure a particular AU-3 of an E1 line that has been mapped to an AU-3, use the au-3 configuration
controller command.

au-3 au-3-number

au-3

Syntax Description

au-3-number A number in the range of 1 to 3.

Defaults No default behaviors or values.

Command Modes Configuration controller

Command History

Release Modification

12.0(14)S This command was introduced.

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

12.0(14)S This command was introduced.

Usage Guidelines An AUG of an STM-1 can be derived from either AU-3s or an AU-4. Use the aug mapping au-4

configuration controller command to map the AUG to an TUG-3 with the following
muxing/alignment/mapping:

C-12 <--> VC-12 <--> TU-12< --> TUG-2 <--> TUG-3 <-->VC-4 <--> AU-4 <--> AUG

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

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

The aug mapping au-4 and au-4 tug-3 commands are available only when SDH framing is configured.

Examples The following example configures AUG mapping to be derived from a TUG-3 and selects TUG-3 1 of

AU-4 1 to configure:

Router(config)# controller sonet 2/0/0
Router(config-controller)# aug mapping au-4
Router(config-ctrlr-tug3)# au-4 1 tug-3 1

12.0(14)S This command was introduced.

Usage Guidelines An AUG of an STM-1 can be derived from either AU-3s or an AU-4. If you configure the AUG mapping

to AU-3, the following muxing/alignment/mapping is configured:

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

If you configure the AUG mapping to AU-4 the following muxing/alignment/mapping is configured:

C-12 <--> VC-12 <--> TU-12< --> TUG-2 <--> TUG-3 <-->VC-4 <--> AU-4 <--> AUG

tug-2 e1 unframed

To create an E1 unframed (clear channel) logical channel group on an E1 line that has been mapped to
a TUG-3, use the tug-2 e1 unframed configuration controller tug-3 command.

To create an E1 unframed (clear channel) logical channel group on an E1 line that has been mapped to
an AU-3, use the tug-2 e1 unframed configuration controller au-3 command.

To remove a logical channel group, use the no form of this command.

Syntax Description

tug-2 number A number in the range of 1 to 7.

e1-number A number in the range of 1 to 3.

unframed Configures an E1 unframed channel.

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
