MERLIN LEGEND BRI system in its default state with minimal system programming. After
completion of testing, the system can be configured to meet customer needs as
indicated by the system planning forms with the assurance that the BRI lines will
function reliably.
Use the following steps as a guideline to install and test the MERLIN LEGEND BRI
system. Refer to the MERLIN LEGEND Communications System Installation manual (555-
620-141 ) and the MERLIN LEGEND Basic Rate Interface Supplemental Reference (555-
