4000 Router Series Voice Command Reference

timeslots-list: Specifies a timeslot list. Timeslots are numbered 1 through 31 for an E1 interface and 1

through 24 for a T1 interface. The timeslot list can contain one or more individual timeslots separated by

commas (for example, 1 or 1, 2, 4), a timeslot range (for example, 5-10), or a combination of the two

forms (for example, 1-14, 15, 17-31).

signal: Specifies the signaling mode for the timeslot set.

r2: R2 signaling.

Usage guidelines

You must create a timeslot set before you can use the subscriber-line command to enter digital voice

interface view and configure voice attributes for the interface.

Examples

# Create timeslot set 5, which contains timeslots 1 through 31 and uses R2 signaling.

<Sysname> system-view

trunk-direction

Use trunk-direction to configure the trunk direction.

Use undo trunk-direction to restore the default.

Syntax

trunk-direction timeslots timeslots-list { dual | in | out }

undo trunk-direction timeslots timeslots-list

Default

Bidirectional trunking applies.

Parameters

timeslots-list: Specifies a timeslot list. Timeslots are numbered 1 through 31 for an E1 interface and 1

through 24 for a T1 interface. The timeslot list can contain one or more individual timeslots separated by

commas (for example, 1 or 1, 2, 4), a timeslot range (for example, 5-10), or a combination of the two

forms (for example, 1-14, 15, 17-31).

dual: Specifies the bidirectional trunk, which can receive and originate calls.

in: Specifies the incoming trunk, which can only receive calls.

out: Specifies the outgoing trunk, which can only originate calls.

Usage guidelines

For R2 signaling to operate correctly, the trunk direction must be incoming at one end and must be

outgoing at the other end. If both ends are using bidirectional trunking mode, use the select-mode

command to tune the routing mode to prevent timeslot contention.
