HP MSR2000/3000/4000 Router Series Interface Command Reference

139
In SF framing, LLB code is sent using the effective bandwidth (slots 1 through 24). In ESF framing, both
LLB code and PLB code are sent/received in the FDL in ESF frames.
You can use this command only when the remote T1-F interface can automatically detect loopback
request code from the network.
Examples
# Send in-band LLB activation request code.

Related commands
ft1 frame-format
ft1 timeslot-list
Use ft1 timeslot-list to bundle timeslots on a T1-F interface.
Use undo ft1 timeslot-list to restore the default.
Syntax
ft1 timeslot-list list [ speed { 56k | 64k } ]
undo ft1 timeslot-list
Default
All the timeslots on the T1-F interface are bundled to form a 1536 kbps interface.

Parameters
list: Specifies timeslots to be bundled. They are numbered 1 through 24. You can specify a single timeslot
by specifying its number, a range of timeslots by specifying a range in the form of number1-number2, or
several discrete timeslots by specifying number1, number2-number3.
speed { 56k | 64k }: Time slot bundling speed in kbps. If 56k applies, timeslots are bundled into an N
× 56 kbps bundle. If 64k (the default) applies, timeslots are bundled into an N × 64 kbps bundle.
Usage guidelines
Timeslot bundling results in interface rate change. For example, after you bundle timeslots 1 through 10
on the interface, the interface rate becomes 10 × 64 kbps or 10 × 56 kbps.
Only one channel set can be created on a T1-F interface, and this channel set is associated with the
current synchronous serial interface. On a CT1/PRI interface, you can create multiple channel sets; for
each of them, the system automatically creates a synchronous serial interface.
Examples
# Bundle timeslots 1, 2, 5, 10 through 15, and 18 on T1-F interface Serial 2/0.
