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 MCU can 
support four Base Stations and up to 16 handsets. The Base Station 
and SpectraLink 6000 Wireless Telephone cables are punched down 
onto the demarc/cross-connect blocks as shown in the demarc block 
diagrams below. Refer also to the diagrams in Chapter 4, section 
Prepare Demarc Blocks and Chapter 5, section Install MCUs
Photocopy the Handset Planning Worksheet and Base Station Location 
Worksheet 
provided in this manual as needed. Use the forms to track 
the Base Stations and handset port assignments connected to each 
MCU. As the Polycom field service engineer makes 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 four Base Stations can be connected on a single MCU. Each 
Base Station uses two pair, one for data and one for power. 
 
 
When cabling an external Base Station or a Base Station with 
wiring that exits the building, protect all Base Station wiring with 
fuse protection. One method is to use a Quick Clip Fuse (Illinois 
Tool Works, Linx Division, SCP-2X2) to provide protection from 
external wiring. 
If the wiring between the MCU 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.
