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 75 — 75 Ω
100 — 100 Ω
120 — 120 Ω
tpif
Syntax [no] tpif
Context config>port>tdm
Description This command creates an IEEE C37.94 teleprotection interface (TPIF) channel.
The no form of this command deletes the port’s TPIF channel.
Default n/a
timeslots
Syntax timeslots timeslots
Context config>port>tdm>tpif>channel-group
Description This command defines the list of DS0 timeslots to be used in the TPIF channel group.
Default 1
Parameters timeslots — specifies the number of consecutive timeslots to be associated with the
channel group. The value must start from the first timeslot. It represents line
bandwidth of n x 64 kb/s, where n is the number of timeslots.
Values 1 to 12
