Chapter 9 Connecting the cables to the BCM50 system
N0027152 01
N0027152 01
Connecting lines and extensions to the RJ-21 telephony connector
You can connect 4 analog lines, 4 analog extensions, and 12 digital extensions to the RJ-21
telephony connector.
If you use the WFC to connect the lines and extensions to the RJ-21 telephony connector, refer to
“Installing the wiring field card (optional)” on page 88
and
“To connect the cables to the wiring
field card (optional)” on page 111
for more information.
To connect the lines and extensions
1
Read the warnings in
“Wiring warnings” on page 103
.
2
Obtain a 25-pair cable with an RJ-21 connector on one end.
3
Remove the appropriate side breakout from the cable management door:
•
If this is the first unit on a BCM50 system with multiple units, remove the side breakout
from the right side of the cable management door.
•
If this is the center unit on a BCM50 system with more than two units, remove the side
breakout from both sides of the cable management door.
4
Plug the RJ-21 connector into the RJ-21 telephony connector on the main unit.
5
Select the appropriate option to secure the RJ-21 connector to the main unit:
•
If you are using a straight RJ-21 connector, use the two supplied screws on the sides of the
connector to secure it.
•
If you are using a right-angle RJ-21 connector, use the supplied screw on the left side of
the connector to secure the left side of the connector. To secure the right side of the
connector, use the supplied cable tie to fasten the 25-pair cable to the anchor on the main
unit.
6
Connect the four pairs of wires for the analog lines to the telephone company demarcation
blocks of the building.
7
Connect the four pairs of wires for the analog telephones to the local connecting blocks.
Danger:
Electrical shock hazards
Electrical shock hazards from the telecommunications network and ac mains are possible
with this equipment. To minimize risk to service personnel and users, the BCM50 system
must be connected to an outlet with a third-wire ground. In addition, all unused slots must
have blank faceplates installed. The covers on all units must be in place at the completion
of any servicing.
Warning:
If you use the same phone line for both an analog trunk and a DSL line,
you must install a DSL filter on the analog trunk to avoid interference with the DSL
modem.
