Cabling the Digital Lifeline

The Mediant 1000 gateway containing either one or two digital modules, each with 1 or 2
pairs of spans can provide a "lifeline" telephone link. In the event of a power failure, a relay
connects trunk 1 to 2, and / or 3 to 4 in the same module. The link is provided by the
closing of a metallic switch inside the module so that the trunk from the PBX is routed from
the module to the PSTN.
