INSTALLATION NOTE
BASIC OPERATION
The TII 87 series Sealed Subscriber Bridge with POTS
Suppression (Bridge) allows high speed DSL transmission
between customer and central office while suppressing
POTS. The Bridge is equipped with a test jack and IDC
terminations (see Figure 1). The RJ-11 plug of test
equipment can be inserted into the test jack to assure a
DSL signal is received from the office. This is the only
time the customer is disengaged from the central office.
INSTALLING THE SEALED SUBSCRIBER BRIDGE
• Remove the Bridge from plastic bag and inspect; if
damaged, replace with an undamaged Bridge.
•
Hold the Bridge with the cover pivot side on right.
• Lower the pivot side edge inside the designated
installation cavity.
• Engage the right end ledge under the catch. (See
Figure 2)
• Push the left side end down until the latch snaps
closed.
SEALED SUBSCRIBER BRIDGE WIRING
• The Bridge has a pair of wires that are to be
connected to the protector module. The customer has
the option of installing a #10 Master lock around the
customer lock hasp (see Figure 1).
• Do not strip wire insulation from wires to be
terminated to protector.
• Dress terminating wires (to protector) over NID
divider.
• Insert and terminate wires into sealed IDC station
protector (see protector installation note for further
details).
•
Open customer security cover on Bridge.
• Lift one Bridge rocker to the open position as shown
(see Figure 1).
•
Dress wires around customer security cover.
•
Hold the customer DSL pair wires between thumb and
index finger (approx. 1/8” separation between wires).
NOTE: Only use one of the rockers. All rockers are
bridged together.
• 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).
• Assure the rocker is in the down position and close
customer security cover.
