4000 Router Series Interface Command Reference

122

Parameters

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

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.

Only one channel set can be created on an E1-F interface, and this channel set is associated with the

current synchronous serial interface. On a CE1/PRI interface, you can create multiple channel sets. For

each of them, the system automatically creates a synchronous serial interface.

Timeslot 0 on E1-F interfaces is used for transmitting synchronization information. A bundling operation

only involves timeslots 1 through 31.

When the E1-F interface is operating in unframed mode, the fe1 timeslot-list command is invalid.

Examples

# Bundle timeslots 1, 2, 5, 10 through 15, and 18 on E1-F interface Serial 2/0.

fe1 unframed

Use fe1 unframed to configure the E1-F interface to operate in unframed mode.

Use undo fe1 unframed to restore the default.

Default

The E1-F interface operates in framed mode.

Usage guidelines

When the E1-F interface is operating in unframed mode, it is a 2048 kbps interface without timeslot

division and is logically equivalent to a synchronous serial interface.

When it is operating in framed mode, it is physically divided into 32 timeslots numbered 0 through 31,

where timeslot 0 is used for synchronization.
