and each loss level represents an approximate 3 dB attenuation of the signal level from the previous

setting. Because digital transmission does not lose volume level as readily as analog transmission

does, it is likely that the receive level may be noticeably higher when using the E1 option. Therefore,

you may need to select a low setting such as Loss 2 for the voice level receive parameter when

programming this feature for E1 lines that are being used exclusively for voice transmission. Further,

if you choose a setting to increase the receive gain, you should carefully examine speakerphone

operation. It is possible to select a receive gain that will, under certain conditions, interfere with

proper speakerphone operation.

TAP (Flash)/Recall

When host system custom calling features are available via a hook-flash signal while on line, the

TAP button functions as a hook-flash button and generates a flash signal when the user presses it.

When custom calling signals are not available, the TAP button functions as a positive disconnect and

recalls dial tone when the user presses it. These features are mutually exclusive. The installer sets the

desired function for the system by programming action. With single–line proprietary telephones, the

Tap function works for internal transferring only. An access code is required to activate custom

calling features.

Telephony Services Application

Programming Interface (TSAPI) Support

The FX II provides support for TSAPI applications. These applications are Novell Telephony

Services* applications developed by third-party software vendors. TSAPI applications run

independently of the FX II yet use its digital communications capability. The FX II’s Enterprise

open architecture interface (OAI) data port provides the hardware interface for the personal

computer (PC) that runs the TSAPI software program. Depending upon the TSAPI application and

its functions, there may or may not be a need to reprogram the FX II’s database feature parameters.

Through Dialing

An installer can connect external telephony equipment to the FX II through a proprietary interface

device or through an IST port. When the installer enables the through dialing feature, DTMF tones

that the external device generates pass through the interface equipment, the FX II, and any line

connection. Also see the paragraph titled Off Premise Extension.

Time and Date

The time designation is in a 12-hour format. Time and date appear on the LCD speakerphone and the

SMDA/SMDR record printout.

Timed and Immediate Recall

If a telephone user places a call on hold and fails to pick it back up within a preprogrammed time,

the call rings the user’s telephone again. While only the telephone that put the call on hold rings, all

other telephones that share call appearance will flash the light for the held call at a hold recall rate.
