2 Call-Handling Scenarios
Network Configuration Scenarios
trunks connected locally and normal calls are made using PSTN facilities
connected to other systems. The systems are linked both by tandem PRI
and tandem tie facilities.
Scenario 5: Large System Hub,
LEGEND Communications Systems are linked to a hub DEFINITY ECS or
DEFINITY ProLogix Solutions system in a star configuration.
The scenarios vary according to the types of tandem trunks, applications, outside
facilities, and network configuration (series or star). They compare and contrast
the following aspects of private networks, supplying both usage and setup
information:
Intersystem call-handling to and from extensions on remote networked
systems
ARS routing and calling via PSTN trunks connected to a remote networked
system
ARS routing and usage when local PSTN trunks are accessed by non-local
users
Remote access planning for non-local users calling out on local PSTN
facilities
Remote access planning for network usage by people who are calling in
either from outside the network or from an extension that is non-local to
their home system
PRI dial-plan routed and DID calling across the network
Considerations for PassageWay Telephony Service clients using the
system's Computer Telephony Integration (CTI) link feature
The scenarios in this section do not show all of the types of equipment, such as
fax machines and single-line telephones, that may be included in systems. They
only include the types of equipment that are relevant to the examples. You can
use the same types of extension equipment in a networked system that you use in
a non-networked system.
To better understand your current system, review Scenario 1 if your network
includes any tandem PRI trunks; review Scenario 2 if your system includes any
tandem tie trunks. Then review the remaining scenario that is most like your own.
When you are planning network changes, review one or more of the scenarios
that involve system components and facilities for which you are planning. Even
though your own network may not be represented here exactly as it exists,
NOTE:
DEFINITY ECS and DEFINITY ProLogix Solutions features and
operations are beyond the scope of this guide. Scenario 5 discusses
the network from the MERLIN LEGEND Communications Systems
perspective.
