INSTALLATION NOTE

1. GENERAL

The tii 3800 Series COCOT (Customer Owned Coin

Operated Telephone) provides a demarcation point
between the telephone service provider network and
the subscriber’s telephone wires. The Network
Interface Device (NID) may contain gel sealed station
protectors (tii Angle Drivers), or other primary station
protectors such as tii’s 355, 356, 127, etc., and sealed
subscriber bridges (tii 95S Series). These primary
surge protection modules provide primary electrical
protection for subscribers. The tii 95S Series provides
subscriber connections and a demarcation test
access point. Each can terminate up to four
subscriber extension line connections which will
automatically disconnect when the customer uses the
RJ-11 port for testing.

NOTE: See separate installation note if the unit is
equipped with tii 95S Series ADSL POTS Splitter module.

Each Angle Driver module can connect one pair of 18-

24 AWG (1.02-0.51mm) central office (c.o.) wire and
one pair of 22-24 AWG (0.65-0.4mm) subscriber
bridge wires. Connections are created with insulation
displacement connection (IDC) blades and are
environmentally sealed.

The NID housing is constructed from rugged, heat and

solvent resistant, UV stabilized materials.

CAUTIONS AND WARNINGS

Use company-approved safety practices and

equipment.

Only solid conductors can be used for connecting to

the Angel Driver and the tii 95S Series Subscriber
Bridges; Do Not Use Stranded Wire.

Stranded or solid wires can be used on binding post

termination primary protectors.

Do not strip insulation from conductors when

terminating to an IDC connector.

If the hook up wire, OSP wire, or central office cable

is physically larger than 22 AWG, a fusing conductor
of 22 AWG or smaller solid copper wire with
thermoplastic insulation must be used. Install the
fuse link per local practices and approval agencies.

This installation note may be used for binding post

terminating primary protectors

To mount to wooden pole or wall, install two screws

through the housing mounting tabs. Secure them to
the required service.

It also contains a magnetic base for mounting to

metallic surfaces.

Prepare and Route Cables, Grounding

Route the central office (c.o.) wire to the housing.
If the cable is shielded, remove 1” of sheath and

attach the ground lug to the shield.
Route the subscriber wire to the housing.
Strip the outer jacket insulation from the subscriber

wire, exposing the insulated conductors.

Connecting Sealed Subscriber Bridge to Sealed
Station Protector (where applicable)

Using a 216 tool, raise the station protector driver by

turning the bolt counterclockwise until the bolt spins

freely, indicating the driver is in the “up” position. Insert

the subscriber bridge conductors into the proper small

top wire ports of the station protector until fully seated

(approx. ¾” or 20mm). Do not strip insulation from

conductors (Figure 2).
While holding the subscriber bridge conductors into

the station protector driver, turn the driver bolt

clockwise and return the driver to the “down” position

(Do not overtighten.) Pull lightly on the subscriber

conductors to verify connection (Figure 3).

Connecting Central Office Wire to Sealed Station
Protector

Using a 216 tool to raise the driver bolt of the station

protector until it spins freely, indicating that the driver

is in the “up” position (Figure 3).
Insert the c.o. wire pair into the two large bottom ports

of the protector (Figure 3) until fully seated.
While holding the c.o. wires into the station protector

driver, turn the driver bolt clockwise and return the

driver to the “down” position (Figure 3). (Do not

overtighten.)
Pull lightly on all wires to verify connection.

Connecting Station Wire to Sealed Subscriber Bridge

Open the subscriber bridge cover to gain access to

top/bottom terminating rockers. Note the lid can be

removed from the base of ease of wire installation

(Figure 4).
Open one unused wire rocker (Figure 4).
Insert the wire pair into the TIP (“T” or Green) and

RING (“R” or Red) rocker until fully seated (approx. ½”

or 13mm). (Do not strip insulation from wire.) Note

that if the wire was previously connected to the bridge,

trim away the last inch (25mm) or so of wire, removing

the area previously scored by the connectors (Figure

4).

Press thumb firmly on rocker until it snaps shut. Route

wires under lid (Figure 5). Repeat as required.

Pull lightly on all wires to verify connection.
Perform all customary tests.
