7.Select the disconnect time for each DID trunk by doing one of the following under the Disconnect Time heading:

To keep the factory setting, check 500 ms.

To change the disconnect time, write the new value (10 to 2550 ms) in the Other column.

NI-1 BRI Connectivity

To ensure proper operation of the BRI line features, the following options must be set on the MERLIN LEGEND system during system programming:

Service Profile Identifier (SPID) for each BRI line B-channel

Directory Number (DN) for each BRI line B-channel

Clock Synchronization for the system

Timers for each BRI module (system provides defaults)

The following affect the operation of the MERLIN LEGEND system. However, they are programmed on the Central Office (CO) switch:

Service Configuration of the BRI lines (IOC “S”, Multiline Hunt)

Hunting pattern for a Multiline Hunt configuration

Service Profile

A Service Profile (SP) defines the interface on a BRI line between a CO and an ISDN terminal. It specifies the parameters and their values necessary to provide services to the terminal. There are standardized capability packages called ISDN Ordering Codes (IOCs) that are configured on the CO at subscription time. The IOC contains information necessary for the CO to provide service to the system.

The MERLIN LEGEND system supports the IOC “S” capability package, which provides alternate voice/circuit-switched data on two B-channels with no packet data capability or supplementary voice features, except for the Calling Party Number/Billing Number (CPN/BN) feature, if available.

In addition to the IOC “S” capability package, the MERLIN LEGEND system sup- ports Multiline Hunt (MLH) service for alternate voice and data hunting if the CO is a Lucent Technologies 5ESS or Northern Telecom DMS-100 switch. For a Sie- mens SSC EWSD switch, MLH service must be provisioned as either voice or data hunting. MLH service is provided through the Multiline Hunt Group (MLHG) feature on Northern Telecom DMS-100 switches, and through the Series Comple- tion feature on Lucent Technologies 5ESS and Siemens SSC EWSD switches.

NOTE:

The MLHG feature on the Lucent Technologies 5ESS and Siemens SSC EWSD switches is not recommended for use with the MERLIN LEGEND system.
