If you have successfully entered the time, you will receive standard dial tone after entering the exit
command digit. Incorrect time settings will result in a busy signal. The date information is not updated
automatically; you must manually set the date after midnight.
Special Dialing Modes
Whenever you begin a new dial sequence with “
Z
”, followed by two digits (00-99), you will hear three
short beeps followed by dial tone. This tone sequence is called
Recall Dial Tone and is similar to the
beeps heard on some phone systems during special dialing modes. P
ARTY
-L
INE
has reserved
Z
67,
Z
61, and
Z
60 for special operational modes (the remaining codes are unused). The Recall Dial Tone
feature can be disabled using jumper J6 (see Table 1).
Caller-ID Call Block (
Z
67) Dial Feature
If you dial “
Z
67” 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
Z
67 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).
Out-of-Area (
Z
61) Feature
If you dial “
Z
61” 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 hanging up and re-dialing the number. The Out-of-Area command (
Z
61) is not
a standard telephone company provided feature and is unique to P
ARTY
-L
INE
. It can be disabled using
jumper J6 (see Table 1).
Caller-ID Corrupt Checksum (
Z
60) Feature
P
ARTY
-L
INE
offers a special feature that allows you to simulate Caller-ID 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 “
Z
60” 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.
J10 CPC Jumper
Whenever a telephone (or phone device) is hung up, a momentary interruption of the phone line
current occurs to simulate the central office’s
Calling Party Control (CPC) feature. You can turn the
CPC feature On or Off by the J10 jumper setting. It can be disabled using jumper J10 (see Table 1).
We recommend that you leave the jumper installed (CPC on).
