SpectraLink Link 150 M3 MCU - Manual (Page 19)

SpectraLink Corporation Installation and Operation
Link WTS – Link 150 M3 MCU
5.7 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 Link 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 section 5.4 Prepare Demarc Blocks and section
6.3 Install MCUs.
Photocopy the and provided in this manual as needed. Use the forms to track the
Base Stations and handset port assignments connected to each MCU. As the
SpectraLink 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.
