H.5 PBX Support
Interfacing the Verbatim to PBX or PABX phone systems can occasionally
present problems. Some PBXs have a non-standard dialtone. Additionally, in
many PBXs, you must first press a special key, like a '9' to get an outside line.
After pressing the '9' there may be a short delay followed by the dialtone for the
outside line.
By turning OFF Phone Fault Detection you can avoid problems with non-
standard dialtones from your PBX system. Then Phone Fault Detect will not
falsely indicate a telephone line interruption.
Even with Phone Fault Detect OFF you can still accomplish dialtone detection
on outside lines. Simply add the Tone Detect key sequence to the phone number
string after the '9' or other digit to request an outside line.
H.5.1 Cautionary Notes About Interfacing to PBXs
Must Be an Analog Line
Some PBX systems are either partially or entirely digital. That is, voice and
signaling information is converted to a digital representation. Voice
information arriving at the PBX from the outside is converted from analog to
digital. Voice information leaving the PBX to the outside is converted from
digital to analog. Phone sets within a digital system may be interfaced by
digital signals only. In such systems it may be difficult, but usually not
impossible, to obtain a "standard" analog phone line to use in interfacing
devices such as a Verbatim . It may be necessary to contact the vendor of your
PBX system for information on addition of analog lines.
M
Lines Can Cause Damage
Caution is advised. Some telephone lines within digital PBXs present voltages
which can be dangerous to RACO's equipment. If you are attempting to
interface a Verbatim inside of a PBX it would be a good practice to have the
phone line you intend to use checked for "unusual" voltages and signals.
With few exceptions, if you can get a standard telephone set to word on a PBX
line then you will be able to make the Verbatim work as well.
