Routing for Outside Calls

This topic examines routing for hypothetical outside calls, to show how the system manager in Scenario 2 maximizes cost benefits from the private network. As you study the example call routes in Table 2–11, page 2-52, review the general setup as described in Table 2–9, page 2-49 and Table 2–10, page 2-50.

Note the following facts about routing for outside calls in this scenario:

■A PRI dial-plan routed call can be routed across the private network to a telephone extension. However, even if ANI information is available, it cannot be displayed at the recipient’s extension. An example is not included, but the display would show information about the tandem tie trunk only, for example: 7,(￿75..

■Remote access callers to one system can dial non-local extension numbers.

■From System C at headquarters, 2B data calls made over the outside PRI facility can achieve a higher data rate, 128 kbps, than intersystem video calls, which are routed over T1 data tie channels at 112 kbps.

■PassageWay Telephony Services clients receive screen pop on incoming customer calls that they receive on outside PRI facilities, but they do not receive screen pop on those rare occasions when calls are transferred from headquarters in Chicago.
