Interfaces
Description This command applies only to a DS-1 port configured with a 'short' buildout. The length command config-
ures the length of the line (in feet). For line lengths longer than 655 feet, configure the DS-1 port buildout as
'long'.
For 'long' buildout the following values are valid:
For 'short' buildout the following values are valid:
0 — 133
134 — 266 For line length from 134 to 266 feet
267 — 399 For line length from 267 to 399 feet
400 — 533 For line length from 400 to 533 feet
534 — 655 For line length from 534 to 655 feet
The default for 'long' buildout is 'NotApplicable' while the default for 'short' buildout is '0 — 133'.
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
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 sig-
naling, 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.
