Chapter 5: MDF connections to stations and thepublic 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
Completing a provisioning plan on page 52.

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 on page41 (modular jacks)
●Station cableson page 42
●Closets on page 43
●Station circuit distribution from equipment roomon page 44
●Connected cable station adapters on page50

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.
