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.
If the cabling between the MCU and the telephone system or to the
Base Station leaves the building, consult the telephone system
manual, the National Electric Code (NEC), and local codes for
instructions on providing lightning and other over-current protection.
