NOTES:

1.In releases prior to 4.2, only AT&T services for Lucent Technologies generic 4ESS, Lucent Technologies 5ESS, and other providers’ emulations of these services are supported. Release 4.2 and later systems support services on NORTEL DMS-100 generic BCS 36 serving local exchange carriers, NORTEL DMS-250 generic MCI07 serving the MCI network, and Digital Switch Corporation DEX 600E generic 500-39.30 serving the MCI network.

2.For the DMS-100 or DMS-250 switch type, you must give special instructions to the service provider to use variant NTNAPRI (Northern Telecom North America Primary Rate Interface) instead of the AT&T protocol. For the DEX600E switch type, instruct the service provider to use the profile p250. For additional information, refer to System Planning or contact your Lucent Technologies representative.

PRI supports routing by dial plan for DID-like call-handling. This is especially appropriate for Caller ID services such as AT&T’s Station Identification/Automatic Number Identification or the AT&T and MCI Dialed Number Identification Service (DNIS) when your company subscribes. DNIS routes incoming 800 or 900 calls according to customer-selected parameters, such as area code, state, or time of call. For example, a customer can specify that calls received from a particular area code be routed to a specific individual or group responsible for accounts in the area.

The system’s PRI platform allows you to choose any combination of the telecommunications company services listed below (your company must subscribe to these).

—MCI Services (Release 4.2 and later systems only). Domestic outgoing long-distance and international voice calls; domestic incoming toll-free 800 voice calls; 900 service numbers; and private network voice calls as well as 56- and 64-kbps restricted and unrestricted circuit-switched data calls.

—Local DMS-100 Services (Release 4.2 and later systems only). Available from local carriers: private network or tie trunk service for calls between the MERLIN LEGEND Communications System and another communications system (such as another MERLIN LEGEND Communications System); outbound WATS for domestic outgoing long-distance calls; inbound WATS for domestic toll-free incoming voice calls; and, foreign exchange service.

—AT&T Services. Domestic outgoing long-distance and voice calls;

56-and 64-kbps circuit-switched data calls with routing by dial plan; 900 service numbers; outbound WATS for domestic outgoing long-distance calls; and domestic toll-free incoming voice calls.
