HP MSR2000/3000/4000 Router Series Interface Command Reference

Usage guidelines
CT1/PRI interfaces support two framing formats, SF and ESF. In SF format, multiple frames can share the
same FSC and signaling information, so that more significant bits are available for transmitting user data.
The use of ESF allows you to test the system without affecting the ongoing service.
Examples
# Set the framing format of interface T1 2/0 to SF.
<Sysname> system-view
[Sysname] controller t1 2/0
[Sysname-T1 2/0] frame-format sf
idle-code (CT1/PRI interface)
Use idle-code to set the line idle code on the CT1/PRI interface. Two types of line idle code are available:
0x7E and 0xFF.
Use undo idle-code to restore the default.
Syntax
Idle-code { 7e | ff }
undo idle-code
Default
The line idle code is 0x7E.
Views
CT1/PRI interface view
Predefined user roles
network-admin
Parameters
7e: Sets the line idle code to 0x7E.
ff: Sets the line idle code to 0xFF.
Usage guidelines
The line idle code is sent in the timeslots that are not bundled into the logical channels on the interface.
Examples
# Set the line idle code to 0x7E on CT1/PRI interface T1 2/0.
<Sysname> system-view
[Sysname] controller t1 2/0
[Sysname-T1 2/0] idlecode 7e
itf (CT1/PRI interface)
Use itf to set the type and the number of interframe filling tags on the CT1/PRI interface. Two types of
interframe filling tag are available: 0x7E and 0xFF.
Use undo itf to restore the default.
