Connecting the main distribution
frame to stations
and the public switched telephone
network
Once the main distribution frame (MDF) is completed and the media gateways are connected to the MDF,
you must connect the MDF to stations (telephones) and the public switched telephone network (PSTN).
You must also have a provision plan at this time. For more information, see
plan on page 134.

Station (telephone) wiring design

Station wiring from the MDF to information outlets are provided by various means. First, station cables
are used to connect the MDF to satellite closets. Then station cables are used to branch out to site closet
locations that are located physically close to information outlets.
Information outlets may be wired directly to the MDF, a satellite closet, or site closet.
The following hardware and cabling is used:
•

Information outlets

•

Station cables

•
Closets
•
Station circuit distribution from equipment room
•
Connected cable station adapters
Information outlets
Information outlets are 8-pin modular jacks. Most of the outlets are wired with push-on connections.
Information outlets are also available that connect to a double modular plug-ended 4-pair station cable
routed from the MDF, a site/satellite location, or an adapter.
Station cables
For clarity a station cable is either a 25-pair cable, multiple 25-pair cable, or 4-pair D-inside wire (DIW)
run from the equipment room, site/satellite location, or adapter to the information outlets. The following
station cables are available. See
25-pair station cable
A25D cable (male to male) between the equipment room and satellite closet. Use a B25A cable between
the equipment room and site closet or adapter.
