INSTALLATION NOTE

1. Description

The TII 97C ADSL POTS Splitter Module is designed for use at
the subscriber premises in a CAC
module houses electronics known as a “POTS Splitter”. The
POTS Splitter allows both voice and data signals to travel over
the telephone line. This device splits the combined signal to
provide separate outputs for both phone and data. The ADSL
POTS Splitter Module must be used along with a Protected
Customer Bridge Module (PCBM) provided in the Outdoor
Network Interface Device. The TII 97C ADSL POTS Splitter
Module and the PCBM’s are interconnected to provide the
subscriber output screw terminals for wiring both voice and
data.

Open the outer cover on the Outdoor NID by loosening the
customer access screw.

3. Installing the TII 97C ADSL POTS Splitter Module into

5. Wiring for Voice and Data

Grommet Preparations: If routing additional wires through

the rubber grommet located at the bottom of the unit, punch a
small hole in the grommet. Do not break through the edge of
the grommet. Doing so may compromise the grommet’s
holding ability.

6. Subscriber Wiring

• Route wires through the grommet located at the bottom
of the unit and dress to the appropriate module(s).

• Dress any excess wire along the side of the base.

DATA Wiring: Connect the subscriber DATA wires to the
screw terminals on the PCBM (Tip to green, Ring to red) (see
Figure 3).

VOICE Wiring: Connect the subscriber VOICE wires to the
screw terminals on the ADSL POTS Splitter Module (Tip to
green, Ring to red).

7. Wiring to Screw Terminals

• Strip conductor wires back approximately ½ inch.

• Wrap the bare wire around the screw terminal between

two washers. Do not overlap wire on the screws.

• Cut off any excess wire after tightening the screw
terminal.

8. Securing the NID Unit

Make sure the wire entry grommet is completely seated into
position in the base. Tighten the customer access screw to
secure the cover.
