2 Call-Handling Scenarios
Network Configuration Scenarios
Scenario 3: Four Systems in a
Series, Mixed Facilities
Like Scenario 1, this example discusses the planning and call-handling for
networking features and routing. It does not describe the business environment in
any detail. In this scenario, the systems are connected in a linear fashion, creating
a series configuration. Three systems are joined by tandem PRI facilities. A fourth
system is connected to one of the others by analog tandem tie trunks.

geographically distant from one another. Systems J and M are peripheral systems
because they do not connect two or more other networked systems.
Note the following general facts about this network:
All four systems are located in the same time zone. System managers
ensure that date and time settings are the same at each system. In this
way, SMDR reports from each system can trace the same call accurately
and clearly as it crosses the network.
System J is the only system that uses tandem tie trunks to connect to the
system. It is directly connected to System K, which is nearby
geographically and located in the same area code.
The system manager at System K is the coordinating system manager for
the network. Any changes at local systems are cleared through this person,
who ensures that the changes do not interfere with network operations. If
changes at one system require changes at other systems as well, the
System K manager sees that the proper modifications are made and that
system forms are updated accordingly.
Each system has its own local voice mail/auto attendant application.
To avoid conflicts, the dial plan of each system is unique within the
network.
Two systems have videoconferencing applications and use them for
meetings.
Two systems have PassageWay Telephony Services applications for use
by fundraisers.
