Configuring a Channelized DS3 Port
Figure 35 depicts the logic of the DS3 port configuration.
Figure 35: Channelized DS3 Port Structure
The following describes steps to configure a channelized port on a 12-port DS3 MDA:
A:ALA-A>config# port 7/1/1
A:ALA-A>config>port# tdm
In order to set the channelized mode on a port, the DS3 parameter must be in a shut down state.
Clear channel uses out-of-band signaling, not in-band signaling, so the channel's entire bit rate is
available. Channelized ports use in-band signalling and must be explicitly enabled.
A:ALA-A>config>port>tdm# ds3
A:ALA-A>config>port>tdm>ds3# shutdown
A:ALA-A>config>port>tdm>ds3# channelized ds1
DS3 frame relay
A:ALA-A>config>port>tdm>ds3# no shutdown
A:ALA-A>config>port>tdm>ds3# exit
In the DS1 context, configure DS0 channel groups parameters. 24 timeslots can be configured per
channel group.
A:ALA-A>config>port>tdm# ds1 1
A:ALA-A>config>port>tdm>ds1# no shutdown
A:ALA-A>config>port>tdm>ds1# channel-group 1
A:ALA-A>config>port>tdm>ds1>channel-group# timeslots 1
A:ALA-A>config>port>tdm>ds1>channel-group# encap-type frame-relay
DS1 frame-relay
A:ALA-A>config>port>tdm>ds1>channel-group# no shutdown
A:ALA-A>config>port>tdm>ds1>channel-group# exit
