Install Demarc Blocks 
The demarcation blocks used to connect the telephone system and 
Base Stations to the MCU should be installed on a typical telephone 
facility backboard. A 1/2 or 3/4” thick board mounted on the wall 
near the MCU is typical. Although this manual uses 66 blocks as 
examples, any standard cross-connect blocks are acceptable. 
 
When cabling an external Base Station or a Base Station with 
wiring that exits the building, protect all Base Station wiring with 
the Quick Clip Fuse (Illinois Tool Works, Linx Division, SCP-2X2) 
before bridging with other Base Station power leads. 
If the cabling 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. 
Assign and Program Ports 
The wire contractor should inform the system administrator which 
port numbers have been designated for the handsets and the remote 
diagnostics modem line. 
The system administrator must assign extension numbers to the 
handsets and plan the functions (trunk access, toll restrictions, system 
features, ringing options, etc.) to be programmed for the handsets. 
This programming will be done after the handsets are registered, but 
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 the system administration document for your PBX.
