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.

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.
