This chapter describes the MDF and the pinout connections to the IPx 800 cage and
external equipment. The main distribution frame (MDF) is the wiring interface for the
Coral IPx system and associated peripheral equipment.
The MDF is often located adjacent to other signaling systems, such as:
„
Paging and public address systems
„
Voice messaging systems
„
Alarm and monitoring systems
„
Closed circuit television
„
Property management systems
„
Building and energy management systems
Therefore, care should be taken to plan the MDF layout before fastening components
to the wall or mounting surface, such as:
„
Trunk circuits
„
Wired and wireless station equipment
„
Database programming terminals
„
Report printers
„
Music and/or audio sources
„
External public address or paging equipment
„
Recording devices
I/O Connections in the Coral
Most connections to the Coral cabinet are made using standard, 25-wire pair, I/O
(input/output) connectors to the Coral IPx 800 rear panel. Cables from the Coral rear
panel are connected to the MDF and from there to “punch blocks”. Individual trunk
and station interface circuits can then be cross-connected from Coral I/O punch blocks
