3. Installation

b) If the wiring is not owned by British Telecom, either:

(i) British Telecom

(ii) The authorised maintainer

(iii) A professional installer after 14 days written notice to the author-

ised maintainer.

Connect the telephone line as follows:

If the telephone line is already terminated with a suitable lead and plug then

insert the plug into the RJ11 connector (see Figure 17).

Otherwise (see Figure 18):

1. Using a three core cable (type 1/05mm CW1308), strip back 5mm of

two cores and feed through one of the cable entries in the rear of the

9751 or 9752 casing. Connect the two cores to the terminals, A and B

on the built communicator.

2. Connect the cable from the A and B terminals on the built in communi-

cator to the corresponding terminals on the BT master box.

3. If other apparatus is required to share the telephone line with the built in

communicator (series apparatus), connect the main apparatus to the

series switched line connections marked A1, B1.

Caution: The connection of only one such series apparatus is allowed

to be connected between a main apparatus (e.g., telephone)

and the PSTN.

Take care to ensure that the A and B line are connected correctly ( i.e.

correct polarity). The built in communicator continuously monitors the line for

Ringing tones.
