MLH service may be configured in either a linear or circular pattern. Current testing of the MERLIN LEGEND system with the CO switches supports linear hunting on a Lucent Technologies 5ESS switch, and circular hunting on the Northern Telecom
The Service Profile consists of the following:
■A Service Profile Identifier (SPID), which is a unique identifier used by the CO to associate an ISDN terminal with a Service Profile.
■A Directory Number (DN) for each BRI line
■If MLH service is not subscribed, only one call to a particular DN will be accepted at any given time, and any station with the line appearance of the BRI line will alert. If MLH is subscribed, the CO will automatically hunt for the next available
■Optional features:
—Calling Party Number/Billing Number (CPN/BN) can also be ordered at subscription time.
The local telephone company normally provides two SPIDs and DNs for each BRI line (also called a Digital Subscriber Line [DSL]) ordered. The SPID consists of a string of digits 0 through 9 not more than 20 digits in length. The DN consists of a string of digits 0 through 9 not more than 10 digits in length. Each DSL will use two lines on Form 3i, Incoming Trunks: BRI Options (800
