Parameter	local: Sets the interface in internal loopback mode.
	payload: Sets the interface in external payload loopback mode.
	remote: Sets the interface in external loopback mode.

Description

n

Use the fe1 loopback command to set the E1-F interface in a loopback mode.

Use the undo fe1 loopback command to restore the default.

By default, loopback is disabled.

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 an E1-F interface.

Example # Set interface Serial 2/0 in internal 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.

Description Use the fe1 timeslot-listcommand to bundle timeslots on the E1-F interface.

Use the undo fe1 timeslot-listcommand to restore the default.

By default, all the timeslots on the E1-F interface are bundled to form a 1984 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.
