3.3. Ending the Call

There is no direct way for a user to end a call from the unit. The unit will close

down and release the line on receipt of the following signals, usually when the

remote party clears:

•

Line polarity reversal

•

A line break (sometimes referred to as a "k break").

•

Receipt of exchange call progress tones (see section 9 for specification)

3.4. Call timer

The phone has a programmable call timer that can limit the maximum call

duration.

When ON, the timer forces the phone back off line after the preset time. This

prevents the line remaining tied if the neither party ends the call. The timer is

factory-set to 7mins by default, but can be set to any value (up to 2¾hrs) or

disabled. See section 7.2.1.

SMART features

This family of products has a wide range of intelligent features including:

•

Monitoring of faults and health status

•

These features are all available over standard, 2 wire telephone lines with no

Application (TMA) available separately, see section 7.3.

Installation

5.1. General

All possible measures must be taken to ensure water, fluid or dust

does not contaminate the internal components of the telephone whilst

unpacking, preparing and installing the telephone in inclement weather

conditions or by negligence.

Failure to do so may invalidate your warranty.

These telephones are supplied without connection leads – cabling to the

telephone network must be supplied and installed by the installer. Because of

this, extra precautions must be observed: installers must ensure that they

have the permission of the owner of the PABX or telephone network to which

the telephone is to be connected, and that installation is carried out by
