channel-group
Syntax [no] channel-group channel-group-id
Context config>port>tdm>ds1>channel-group
config>port>tdm>e1>channel-group
Description This command creates DS0 channel groups in a channelized DS1 or E1 circuit. Channel groups
cannot be further subdivided.
The no form of this command deletes the specified DS1 or E1 channel.
Default None
Description channel-group-id — Identifies the channel-group ID number.
Values DS1: 1 — 24
E1: 1 — 32
channelized
Syntax channelized {ds1 | e1}
no channelized
Context config>port>tdm>ds3
Description This command specifies that the associated DS-3 is a channelized DS-3 with DS-1/E-1 sub-channels.
Depending on the MDA type, the DS-3 parameters must be disabled if clear channel is the default (for
example, on m12-ds3 MDAs). Clear channel is a channel that uses out-of-band signaling, not in-band
signaling, so the channel's entire bit rate is available. Channelization must be explicitly specified. The
no form specifies the associated DS-3 is a clear channel circuit and cannot contain sub-channel DS-
1s/E-1s. The sub-channels must be deleted first before the no command is executed.
Default no channelized.
Parameters ds1 — Specifies that the channel is DS-1.
e1 — Specifies that the channel is E-1.
cisco-hdlc
Syntax cisco-hdlc
Context config>port>tdm>ds1>channel-group
config>port>tdm>ds3
config>port>tdm>e1>channel-group
config>port>tdm>e3
Description This command enables the context to configure Cisco HDLC parameters. Cisco HDLC is an
encapsulation protocol that governs information transfer. It specifies a data encapsulation method on
synchronous serial links using frame characters and checksums.
