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.
