A-16
General Description
This feature automatically routes outgoing on or off-net calls over alternate facilities when the first-choice trunk
group is busy. The user selects the first-choice route by dialing the corresponding access code, and the equipment
then routes the call through alternate trunk groups only if the first is busy. The NEAX2400 IPX will also add or
delete digits, when necessary, to complete the call to the desired station.
Operating Procedure
No manual operation is required.
Service Conditions
1.
No indication is provided to a user if the call is routed over first-choice or subsequent choice facilities.
2.
STATION MESSAGE DETAIL RECORDING [S-10] may be used in conjunction with this feature.
3.
The same route can be included in two or more alternative groups.
4.
The total number of routes that can be included in a single route advance group is 15.
5.
The total number of routes that can be contained in the system is 255.
6.
The same route can be included in two or more alternative groups.
7.
The maximum number of trunks to be included in a route is 255.
8.
ALTERNATE ROUTING [A-16] occurs only when the dialed code accesses the first-choice trunk group
in the ALTERNATE ROUTING list.
9.
The outgoing call to the trunk belonging to the different node in the FCCS network is available. For more
detailed information, see the NEAX2400 IPX Fusion Network System Manual.
Interactions
1.
ALTERNATE ROUTING may be affected by TOLL RESTRICTION -3/6 DIGIT [T-7]. For example,
two routes of WATS provide the same service but for two separate Route Restriction Classes. Stations of
one RSC will be allowed to advance to the second WATS route while the other RSC will not.
2.
If LEAST-COST ROUTING [L-5] is used, ALTERNATE ROUTING is not used. However, they may be
made available in the same system.
3.
ALTERNATE ROUTING provides for no digit translation, therefore, only routes of the same type may
be used. Keep this in mind when coordinating Route Advance groups consisting of DDD and FX routes.
Programming
STEP 1:
ANPD - Reserve a number level for trunk access. Assign for Connection Indexes Normal (N) and
Hooking (H). Assign NND values in accordance with a predetermined numbering plan.
STEP 2:
ASPA - SRV = OGCA (Outgoing Call Advance), assign access code, count number of Routes in a
Route Advance Group, and the Route Numbers in the group.
STEP 3:
ARSC - A station must be assigned an RSC that will allow access to the routes in the ALTERNATE
ROUTING Route Advance Group.
STEP 4:
AMND - must be assigned for the number of digits dialed.
