Configuring outbound calls
When a MAX unit dials out, it routes the outbound call from the originating slot to a WAN
channel to place the call. It looks for channels whose Ch N Trn Grp (or B1 Trnk Grp or B2
Trnk Grp) parameter matches the trunk-group prefix in the number dialed, that is, the prefix in
the Dial # setting of the Call profile used to place the call.
(Note that inverse mux calls have priority over other types of outgoing calls on those channels
whose Ch N Slot parameters point to invs-mux modules.) Inverse-mux calls are configured in
call profile, as described in “Assigning nailed channels to groups” on page 3-12. If no trunks
have available channels, the call is not placed.
Note: An available channel within the trunk group is one that is not assigned to any port (its
slot/numbers are zero) or is assigned to the port that originated the call. Channels assigned to
another port are not available.
Enabling trunk groups
A trunk group is a group of channels that has been assigned a number. If you enable trunk
groups, dial-out numbers must include a trunk-group number as a dialing prefix, and all
switched channels must be assigned a trunk-group number if they are to be available for
outbound calls. The following setting enables trunk groups:
System
Sys Config
Use Trunk Grps=Yes
Note: Trunk-group numbers 2 and 3 have special meaning, as described in the next two
sections. Only trunk groups 4–9 are available for assignment to channels.
From preceding page
Is bearer service of call V.110?
Yes
Route to any V.110 module.
If none available, reject call.
Is bearer service of call Voice and are digital
modems installed?
Yes
Route to any available digital
modem. If none available, reject
call.
If unit is not waiting for a second call of a dual-port
pair (invs-mux), answer the call on the first
available serial-host port that is not a secondary port
of a dual-port pair.
If unit is waiting for a second call of a dual-port
pair, answer call on that port if it is available.
No
No
Are both true: Excl Routing=No and the slot
parameter (Ch N Slot, B1 Slot, B2 Slot)=0 or null?
No
Reject call.
