Operation / Testing
The CB telephone has no buttons and no means of dialling or signalling.
It can only be used to make calls where calls are routed by the exchange, for
example the BT Direct Connect service or PABXs or concentrators specifically
configured to do so. Seek assistance from your telephone service provider or
infrastructure maintainer to configure this facility.
To make a call, lift the handset. The exchange should establish the call.
When the other party answers, two way speech is possible.
To end the call, replace the handset on its cradle.
To answer a call, wait for ringing (a loud, two-tone warble), then lift the
handset. Two way speech should be possible as before, and the call is ended
by replacing the handset.
3.1. Call timer
The phone has a selectable call timer that can limit the maximum call duration
to approximately 7 minutes.
When on, the timer forces the phone back off line after the preset time. This
prevents the line remaining tied if the handset is left off-hook. The timer is
factory-set to OFF by default.
3.2. Handset integrity alert
If configured, this feature will disable the call timer if the handset integrity loop
is broken. This means that, if the handset is detached (for example by
vandalism), the telephone will remain permanently on line even if the call timer
is on.
This provides a method of alerting the signal box or control centre that the
handset is damaged and needs urgent attention.
WARNING: this option should only be used on PABXs or concentrators
configured to expect the alert condition. Not for use on the PSTN.
This is a factory-configured option. Telephones with this option have an
internal label marked "Handset Integrity Alert, the call timer is disabled if the
handset integrity loop is broken".
