Syntax mode {access}

Context config>port>tdm>ds1>channel-group
config>port>tdm>e1>channel-group
Description This command configures a TDM channel for access mode operation. An access port or channel is used for
customer-facing traffic on which services are configured. A Service Access Point (SAP) can only be
configured on an access port or channel. When a port is configured for access mode, the encap-type cem
must be specified to distinguish the services on the port.
The no form of this command restores the default.
