line-impedance
Syntax line-impedance {75 | 100 | 120}
Context config>port>tdm
Description
This command configures the line impedance of a port. Line impedance is set on a per-port basis and ports
on the same card can have different values. Before changing the line impedance of a port, the port must be
shut down.
Default 100 for DS1
120 for E1
Parameters
100 for DS1
120 or 75 for E1
channel-group
Syntax [no] channel-group channel-group-id
Context config>port>tdm>ds1
config>port>tdm>e1

further subdivided.
The no form of this command deletes the specified DS1 or E1 channel.
Default None
Description
