INSTALLATION NOTE
BASIC OPERATION
A Customer Bridge Module (CBM) maintains a constant
direct connection between customer and central office
service provider. The CBM is equipped with a customer test
jack (see Figure 1). Customer can insert the RJ-11 plug
from a working telephone into this test jack to assure a
signal is received from the central office. This is the only
time the customer is disengaged from the central office.
INSTALLING CUSTOMER BRIDGE MODULE
Remove CBM from plastic bag and inspect for damage;
if damaged, replace with an undamaged CBM module.
Insert CBM module into Network Interface Device (NID)
(see Figure 2).
CBM WIRING
Two independent telephone pairs can be connected to
a single CBM module.
Do not strip wire insulation from wires to be terminated
to CBM.
CAUTION: TO REDUCE THE RISK OF PERSONAL
INJURY, INSERT A RJ-11 PLUG INTO THE
CUSTOMER TEST JACK PRIOR TO MAKING ANY
WIRING CONNECTIONS.
Dress terminating wires (to protector) over NID divider
(see Figure 2).
Terminate TIP (GRN) & RING (RED) wires to station
protector (see protector installation note for further
details).
Lift CBM rockers to the open position as shown (see
Figure 1).
Hold the customer telephone wires between thumb and
index finger (approx. 1/8” separation between wires).
NOTE: Wires should be aligned to the corresponding holes.
Green wire to the “T” (GRN) labeled wire guide and the
Red wire to the “R” (RED) labeled wire guide.
Insert wires into wire guides at the same time until they
bottom out.
While holding wires in wire guides, terminate rocker
with thumb (lower rocker all the way) (see Figure 3).
Assure rocker is in the down position and close
customer security cover.
CUSTOMER TELEPHONE WIRE INTEGRITY TESTING
Open customer security cover.
Insert RJ-11 plug into customer test jack to isolate telco
and customer wiring.
Lift rocker to the up position.
Insert customer telephone wire into rocker wire guides
as shown (see Figure 4).
Terminate rocker (lower rocker all the way).
Using an ohmmeter, insert probes into test ports as
shown (see Figure 4), and check for continuity.
Wires are ok if meter shows a reading.
Repeat test for all sets of customer telephone wires. If
the customer telephone wire does not show a meter
reading, then it has a break in it.
Close customer security cover and inform customer.
CENTRAL OFFICE SIGNAL TESTING
Using a working telephone, insert telephone RJ-11 plug
into customer test jack (see Figure 5).
Wait a few seconds, lift receiver, and listen for tone.
If tone is not present, then contact central office service
provider.
If tone is present, then a problem exists in the customer
telephone wires.
