* DEFINITY ECS and DEFINITY ProLogix Solutions systems do not have a Switch Type setting. The Interface field on such a system
identifies the type of the DEFINITY ECS or DEFINITY ProLogix Solutions system, not the type at the other end of the tandem trunk as on
MERLIN LEGEND Communications Systems. If the Interface field specifies
Network
, as it typically might, the MERLIN LEGEND
Communications Systems specify MERLIN LEGEND-Ntwk. If the Interface field specifies
User
, the MERLIN LEGEND Communications
Systems are programmed with the MERLIN
LEGEND-PBX setting.

ARS Routing: Calls

Area Codes
DEFINITY ECS or DEFINITY ProLogix
Solutions system manager
determines appropriate restrictions.
All programmable routes (Default
Local, Default Toll, Dial 0 tables)
specify the main pool of tandem PRI
trunks.The Special Numbers Table
routes emergency calls to the correct
local services and also routes IXC calls
through System A. All ARS tables must
prepend a 9 (ARS access code).
Area Code Tables specify routing to
PRI tandem trunk pools connected to
System A for calls to other Colorado
area codes as well as to more distant
area codes.
ARS Routing: Calls
to Distant Area
Codes
No calls are routed through other
systems, even calls to the 303 (Denver,
CO) area code.
All routing specifies the main pool, 70,
where all tandem PRI facilities are
connected. FRLs are adjusted
according to the cost of the call and
the job requirements of the user.
To reach customers, agent outcalls are
routed to PSTN PRI B-channels
connected to System A, which
subscribes to OUTWATS services for
this purpose. The FRL for these routes
is 2.
