R2511-HP MSR Router Series Voice Command Reference(V5)

146
Parameters
timeslots-list: Timeslot range. Timeslots are numbered 1 through 31 on an E1 interface and 1 through 24
on a T1 interface. You can specify a single timeslot by specifying a number, a range of timeslots by
specifying a range in the form of number1-number2, or several discrete timeslots by specifying number1,
number2-number3. Examples are 1-14, 15, 17-31.
dual: Bidirectional trunk.
in: Incoming trunk.
out: Outgoing trunk.
Usage guidelines
This command applies to R2 signaling only.
An incoming trunk carries incoming calls but not outgoing calls while the outgoing trunk does the
contrary. A bidirectional trunk carries both incoming and outgoing calls.
For R2 signaling to operate correctly for call connection, you need to make sure that the trunking mode
is incoming at one end of the trunk and outgoing at the other end. If both ends are using bidirectional
trunking mode, use the select-mode command to tune trunking policy to prevent timeslot contention.
In addition, avoid using bidirectional trunking mode at one end and outgoing mode at the other end,
because this can lead to failures of outgoing calls at the end in bidirectional trunking mode.
Examples
# Set the trunking mode to bidirectional for TS set 5 on interface E1 1/0.
