2 Call-Handling Scenarios
Network Configuration Scenarios	Page 2-16

■Remote access planning for private network usage by people who are calling in either from outside the private network or from an extension that is non-local to their home system

■PRI dial-plan routed and DID calling across the private network

■UDP routing for centralized VMS/AA

■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 private 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 private network changes, review one or more of the scenarios that involve system components and facilities for which you are planning. Even though your own private network may not be represented here exactly as it exists, information in a scenario that describes a similar configuration, application, or facilities can be helpful to you.

If you are planning for a private network using Release 6.0, disregard the information about centralized VMS/AA.

Scenario 1: Two Systems, Tandem PRI Facilities 2

In this scenario, two MERLIN LEGEND Communications Systems are connected in a series configuration via tandem PRI trunks, which provide the best support for features, call-handling displays, centralized VMS/AA, and performance across private networks.

In this private network, the two system managers work closely together and maintain copies of system forms for both systems. If changes must be made, they first discuss them and assess their impact on the private network.
