The MM717 DCP media module provides 24 DCP ports of two-wire DCP functionality exposed
as a single 25-pair amphenol connector. The DCP ports are exposed by connecting the module
via a standard amphenol cable to a punch-down block with RJ-11 jacks. The MM717 allows you
to use one of the smaller media module slots for a large number of DCP telephones.

● Trunk signaling to support US and International CO or tie trunks
