Reliability and security
The TN568 alarm circuit pack on the DEFINITY AUDIX system has its own
processor that allows maintenance and diagnostic access if the main processor
fails. A series of LEDs on the faceplate lets on-site technicians check system
status. There also is a robust set of built-in diagnostics that technicians can
access either on-site or remotely through a separate modem. A special
alarm-originating feature helps speed problem diagnosing and correction.
The system routinely performs self diagnostics. If it detects a problem, the system
automatically dials a remote maintenance center and produces a detailed alarm
message with diagnostic specifics. The remote maintenance center staff
responds quickly via the remote access port and external modem to perform fur-
ther diagnostics, isolates the problem, and takes corrective action. As a back-up,
the DEFINITY AUDIX system can send an alarm message to the switch.
Easy installation and expansion
Lucent Technologies specifically designed the DEFINITY AUDIX system for easy
installation. There are no special power or cabling adjustments required.
System expansion is simple. All the hardware required for the full 12 ports is
included in the initial DEFINITY AUDIX system. If you start with fewer than 12
ports initially, Lucent Technologies can then activate additional ports through a
simple software change that technicians download remotely. There is no need to
modify the basic hardware.
Improved clarity
A speech processing algorithm developed at Bell Laboratories encodes
at 16 kbps, giving the DEFINITY AUDIX system a major advantage over its
competitors in that it can store more messages in a smaller space.
The algorithm also improves the speech quality; it provides superior voice quality
in system prompts, users’ personalized greetings, and the voice messages them-
selves. Bell Laboratories’ listening studies show that the message playback clarity
is unsurpassed in the voice messaging industry.
Enhanced speed-up/slow-down of message playback is now offered because of
this new algorithm with no loss of clarity. DEFINITY AUDIX system users can play
back messages twice as fast or at half speed with no distortion in pitch.
