Configuring Channelized STM1 Interfaces
To specify the channel number, include it after the colon (:) in the interface name.
For example, a Channelized STM1-to-E1 PIC in FPC 1 and slot 1 will have the following
physical interface, depending on the media type:
The E1 channel number can be from 0 through 62.
This section contains the following topics:
Configuring Channelized STM1 Interface Properties
To configure the interface properties for Channelized STM1-to-E1 PICs, include the
e1-options
configurations list all the valid statements.
To specify options for each of the E1 channels on the Channelized STM1-to-E1 PIC,
include the
NOTE: When a channelized STM1 interface experiences a line transition, the E1
channels configured in unframed mode log a large number of drops (around 24,000)
as the channelized STM1 interface clocks resynchronize. This does not occur on
framed channels, because the framing resynchronizes clocks very quickly.
To specify options for the SONET/SDH side of the connection, include the
