Party-Line Quick Reference Page 6 © Jan 2004
PARTY-LINE has reserved Z60, Z61, Z62, Z67, Z90, and Z91 for special operational modes (the
remaining codes are unused). The Recall Dial Tone feature can be disabled using jumper J6 (see
Table 1).
Distinctive Ring Override (Z62) Feature
If you dial “Z62”, followed by the phone number, the call will use a standard ring instead of the
distinctive ring pattern. This command (Z62) is not a typical telephone company provided feature and
is unique to PARTY-LINE. It can be disabled using jumper J6 (see Table 1).
Special Caller-ID Dialing Modes
Whenever you begin a new dial sequence with “Z”, followed by 60, 61, or 67, you will activate special
Caller-ID dialing features. These features are:
Caller-ID Corrupt Checksum (Z60) Feature
PARTY-LINE offers a special feature that allows you to simulate Caller-ID (CLASS/FSK)
broadcast errors. This feature is perfect for use by hardware and software developers so that
they can test their Caller-ID based products under simulated noisy line conditions. To use the
corrupt checksum
feature, dial “Z60” before your local or long distance number (this code must
be repeated for each call). Your display box will show an error message or will remain blank.
Out-of-Area (Z61) Feature
If you dial “Z61” before your local or long distance number, the “Out-of-Area,” “Number
Unknown,” or related message, will appear on your Caller-ID display box. This code must be
repeated for each call, and can be canceled by hangingup and re-dialingthe number. The Out-
of-Area command (Z61) is not a typical telephone company provided feature and is unique to
PARTY-LINE. It can be disabled using jumper J6 (see Table 1).
Caller-ID Call Block (Z67) Dial Feature
If you dial “Z67” before your local or long distance number, the “Number Blocked” or “Private”
message will appear on your Caller-ID display box. As with the phone company feature, the
Z67 code must be repeated for each call, and can be canceled by hanging up and re-dialing
the number. It can be disabled using jumper J6 (see Table 1).
Visual and Audible Message Waiting Indicator Feature
PARTY-LINE can operate the popular “Illuminated Message Waiting” feature that is found in
CLASS/FSK central office areas. Some agencies call this
Visual Message Waiting Indication (VMWI)
.
Party-Line sends the BELLCORE CLASS/FSK specified
single data message formatted
VMWI signal.
The
stutter dial tone
method is also provided to ensure compatibility with older indicator systems.
Controlling your indicator unit is performed using the Z90 and Z91 commands. You won’t hear the
telephone ring - just hang up after all the dialed digits are entered.
Your handset beeps if the request is accepted or provides a busy tone if the FSK signal can’t be sent.
There are two busy signal situations. A normal busysignal is heard if you dialed an incorrect extension
number and
high tone
busy is heard if the extension is in use (try again when the station is available).
Although the high tone busy indicates that the FSK signal was not sent, the stutter feature will work
normally.
