Codes
* 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.
System O: Atlanta, GA
(Area Code: 404)
MERLIN LEGEND-Ntwk
51 for a system that is within 200 miles
and is not a MERLIN LEGEND
Communications System (System A)

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).
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.
System N: Denver, CO
(Area Code: 303)
MERLIN LEGEND-Ntwk
41 for a system that is more than 200
miles away and is not a MERLIN
LEGEND Communications System
(System A)
9
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.
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.
