received. Units that fail due to abuse or normal wear
should be discarded.

3. INSTALLATION – PREPARATION

If there are any outboard electronic packages

mounted beside the tii 325 or tii 326 station
protector, they may have to be moved. The tii
760 Series Adapter requires a clear space of two
and one-half inches on both sides and top of the
station protector.

After ensuring that adequate space is available

to mount the tii 760 Adapter, remove and discard
the station protector cover.

1. GENERAL

The tii 760 Universal Network Adapter is

designed to retrofit either a tii 325 or tii 326 one
pair or two pair station protector.

The tii 760 is furnished complete with customer

wiring bridge / RJ-11 modular jack with spade
tipped leads for one pair. The tii 760-2 is
similarly equipped for two pair.

No special tools are required to install or

maintain this product.

The tii 760 is equipped with a cover tab that

allows the customer to lock the unit, but allows
the Telco to override the lock.

The interior has a set of hinged covers that

keep the Telco protector modules and station

electronics out of the customer’s view and

touch. They may be accessed with a 3/
head terminal wrench or a pin-in-head wrench.

The customer wiring bridge and the RJ-11

modular jack are press fit and readily field
replaceable.

The tii 760 Series Universal Network Adapter is

equipped with four card slots which allow a
variety of station electronics to be fitted to the
customer line.

If the hook up wire or OSP cable is physically

larger than No. 22AWG, a fusing conductor of
No. 22AWG solid copper wire with
thermoplastic insulation or No. 22AWG copper
clad steel (bridle wire) shall be employed.

Slide the tii 760 Adapter over the protector base

all the way to the wall. The tii 760 is designed to
fit snugly over the base of the tii 325 and tii 326,
but does not require excessive force to install.

Locate the RED and GREEN spade tipped wires

coming from the RJ-11 jack on the right hand
side and terminate them on the Ring and Tip
terminals of the upper protector module
respectively. Observe polarity.

If the tii 760 Adapter is fitted for two lines, and

the second protector module is in place, locate
the RED and GREEN spade tipped wires coming
from the RJ-11 jack on the left hand side.
Terminate them on the ring and tip terminals of
the second protector module. Observe polarity.

Depending on local practice, the YELLOW

spade tipped wires may be terminated on the
ground post, or taped to prevent electrical
interference and dressed out of the way.

Carefully inspect the work performed for shorts,

crosses, grounds, and polarity. Close the inner
door and secure it by tightening the black nylon
nut to the ground post of the protector base.

Remove the plug from the RJ-11 jack. For

those units supplied with protective warning
cover(s), lift the protective warning cover(s)
exposing the customer bridge.

Make a hole in the soft vinyl grommet located

under the right hand customer wiring bridge.

second line is to be terminated, follow the
instructions in Paragraph 4.09 using the left
hand customer wiring bridge.

Replace protective warning cover(s) over

customer bridge(s) where provided and reinsert
the plug into the RJ-11 jack, making certain that
it is properly seated, then close the outer door
and secure it by tightening the screw.

5. INSTALLATION – WITH ELECTRONICS

Follow the steps outlined in Section 3.00 for

installation preparation.

If there are existing electronics mounted

outside the station protector, it will be
necessary for you to carefully note how they are
wired into the circuit.

Electronic packages that are mounted outside

the station protector, having terminals for
station wire connection and factory installed
cable for connection at the protector, may be
installed as described in the following sections.

Mount the tii 760 as outlined in Section 4,

second, third and fourth bullets.

Carefully remove the station wires from the

outboard electronics module.

Place a jumper cable (piece of inside wire) at

least 18” long from the card slot section of the
tii 760 Adapter through the protector grommet
to the outboard electronics module.

Terminate the RED, GREEN and YELLOW

wires onto the appropriate terminals of the
electronic module.

Dress the other end carefully around the

protector, and terminate the RED, GREEN and
YELLOW wires onto three of the wiring posts in
the card slot section of the tii 760 Adapter.

Locate the spade tipped leads associated with

the RJ-11 jack to be used, and terminate them
on the wiring posts with the jumper cable.
Observe polarity.

Terminate the customer’s inside wire following

the steps in Section 4, eighth through twelve
