Industry Standard Telephone Support

The FXT supports a wide variety of features on industry standard (IST) telephones.

Distinctive Ringing

An industry–standard telephone can sound one ring cadence for intercom calls and another for outside calls.

You must select the ringing style in station class of service programming.

DTMF Receiver–Time-out

You can program the amount of time that the system waits to receive a DTMF tone on an industry–standard

telephone. The DTMF receiver–time-out feature applies to the time between a user’s lifting the handset and

pressing a dialpad digit.

Do Not Disturb (DND)

You can dial a feature code (#01 by default) from your industry standard telephone and put the telephone

into a do not disturb (DND) condition. While in this condition, an outside call forwards to another station or

to the attendant according to the call forwarding feature. An intercom call will not ring the DND station and

the system sends a fast busy signal to the caller to distinguish the DND from a standard busy line.

Flash Time

The flash time is the timed length of the signal delivered when a user presses the hookflash (or TAP)

button. The installer can program both the minimum and maximum times that define the IST flash.

Hold Confirmation

Hold confirmation allows the industry–standard telephone users to have positive tone feedback while on

hold.

Offhook Treated As Busy

When an industry-standard telephone user takes the telephone’s handset off hook, the IST station appears

busy to the system. This feature prevents the system from ringing an IST station while the station is idle and

off hook making it unable to sound audible ringing.

Message Wait Retrieval Access Code

This feature allows IST station users to respond to a message waiting condition without using the central

message desk. They do this by dialing a special intercom feature code that lets them respond directly to a

waiting message.

Ring Frequency

The system installer can set a ring frequency of 25 Hz for international applications or set a ring frequency

of 21 Hz for domestic applications. He or she must choose a setting that matches the frequency of the

installed ring generator.
