will be faster if it is planned in advance by verifying the parameters 
and features on the current telephone system and-wired phones. 
For details, refer to the LinkPlus Interface Guide for the type of 
telephone system for the system controller in use. 
Connect Cables from Base Stations and Phone 
Lines to Demarc Blocks 
Two-pair twisted cable from Base Stations installed throughout the 
facility converge at the demarc block or backboard. Each Interface 
Module can support six Base Stations and 16 handsets. The Base 
Station and handset cables are punched down onto the Interface 
Module cross-connect blocks as shown in the demarc block diagrams 
below. 
Photocopy the Base Station Location Worksheet and Extension 
Assignments Worksheet
 as needed. Use the forms to track the Base 
Stations and handset port assignments connected to each Interface 
Module. As the field service engineer punches down each Base 
Station or handset connection, fill in the information on the form to 
identify the position of the Base Station or handset (the building and 
floor number, for example) and a detailed description of the location 
(perhaps a room number). A copy of this form should be posted near 
the cross-connect block. 
 
Up to six Base Stations can be connected on a single Interface 
Module. Each Base Station uses two pair; one for data and one for 
power, so 12 pairs will be used to wire six Base Stations. 
 
 
When wiring an external Base Station or a Base Station with wiring 
that exits the building, protect all Base Station wiring with the Quick 
Clip Fuse (Reliable Electric RSCP-2) before bridging with other 
Base Station power leads. 
If the wiring between the MCS300 and the telephone system leaves 
the building, consult the telephone system manual, the NEC, and 
local codes for instructions on providing lightning and other over-
current protection.
