Purpose
Configures the SONET port transmit clock source, where the
internal keyword sets the internal clock and the line keyword sets
the clock recovered from the line.
Use the line keyword whenever clocking is derived from the
•
network. Use the internal keyword when two routers are
connected back to back or over fiber for which no clocking is
available.
line is the default keyword.
•
Internal clocking is required for SRP interfaces.
Note
Configures the controller framing for Synchronous Digital
Hierarchy (SDH) framing.
SONET framing (sonet) is the default.
Specifies the administrative unit (AU) group and enters AU path
configuration mode. For AU-3, the valid range is:
1 to 3—1-Port Channelized OC-3/STM-1 SPA
•
1 to 12—2-Port Channelized OC-12c/DS0 SPA
•
The au command does not specify the AU type. It specifies
Note
the number of the AU group for the AU type that you want
to configure. The range for the AU command varies based
on whether you are configuring AU-3 or AU-4.
Sets the mode of interface at the AU level. AU-3 paths can be
mapped to c11-t1 or c12-e1 on supported SPAs.
Exits to global configuration mode.
Enters T1 controller configuration submode and specifies the T1
controller name and interface-path-id with the
rack/slot/module/port/auNum/t1Num notation.
Sets the channel-group number to which time slots are assigned.
The range is from 1 to 28.
