Configuring DS1 or E1 SSM

Use the following CLI syntax to configure Synchronization Status Messaging (SSM) for DS1 or E1 TDM ports.

Note:

Only g704 framing mode should be used with E1 SSM. The no-crc-g704 and e1-unframed framing modes are not compatible with E1 SSM.
ssm-bit applies only to E1 SSM.
Only esf framing mode should be used with DS1 SSM.

CLI Syntax:

port port-id
    tdm
        ds1 | e1
            ssm
                [no] shutdown
                [no] ssm-bit sa-bit
                [no] tx-dus

The following CLI syntax shows an example of configuring SSM on an E1 port.

Example:

config# port 1/3/1
config>port# tdm
config>port>tdm# e1
config>port>tdm>e1# ssm
config>port>tdm>e1>ssm# ssm-bit 4
config>port>tdm>e1>ssm# tx-dus

Use the config port info command to display port configuration information.
