Example

Loopback is intended for checking the condition of interfaces or cables. Disable it otherwise.

The three loopback modes cannot be used at the same time on a T1-F interface.

# Set T1-F interface Serial 2/0 in local loopback mode.

Parameter list: Specifies timeslots to be bundled. They are numbered 1 through 31. You may 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.

Description Use the ft1 timeslot-listcommand to bundle timeslots on a T1-F interface.

Use the undo ft1 timeslot-listcommand to restore the default.

By default, all the timeslots on the T1-F interface are bundled to form a 1536 kbps interface.

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, however, you may create multiple channel sets; for each of them, the system automatically creates a synchronous serial interface.

Example # Bundle timeslots 1, 2, 5, 10 through 15, and 18 on T1-F interface Serial 2/0.
