Passwords (3 - 10 digits, any combination of DTMF digits 0-9) Detect and accept: (see DTMF Receive Signal Requirements)
# at end of password must be entered within 16 seconds of
answer tone (if enabled), or unit will disconnect. Error tone is
returned 16 seconds after the last DTMF digit entry.
Seizure of outgoing line
With password enabled
< 250 ms after valid password entered. Audio path is open
for 2 seconds after seizure.
With password disabled
< 250 ms of ring trip. Audio path is open for 2 seconds after
seizure.
Control Codes
Connect mode signal
Takes unit out of command mode and into connect mode.
(Defaults:
**
).
Disconnect
Causes unit to disconnect. (Default
# #)
Switchhook flash
Opens outgoing line for 550
±
50 ms. (Default
∗
#)
Disconnect timer
Programmable for 1 - 99 minutes. Timer starts at cut
through. Warning tone 16 seconds before disconnect.
Restriction codes
10 maximum, up to 5 digits each. May include
∗
in any
position as a wild card for any digit 0-9. Any or all codes can
be assigned to each security code. Unit will disconnect within
100 ms of detecting a restricted sequence.
Reseize
Sends an on-hook signal to the out port.(Default **) opens
outgoing line for 2 seconds. Second digit must be entered
within the programmed interdigit time (default 1 second) of
the first digit.
Disconnect
Causes unit to disconnect. (Default # #) Second digit must
be entered within the programmed interdigit time (default 1
second) of the first digit.
Switchhook flash
∗
# (default) opens outgoing line for 550 ms. Second digit
must be entered within the programmed interdigit time
(default 1 second) of the first.
Disconnect timer
Programmable for 1 - 99 minutes. Timer starts at cut
through, does not reset for retrials, i.e., time on each call is
cumulative. Warning tone 16 seconds before disconnect.
Dial tone detect
Zero crossing detector detects presence of tones from 305 to
640 Hz.
1000 Hz tone detect
Zero crossing detector detects presence of 1000 Hz tone.
Must accept 1000
±
50 Hz
Must reject (tone < 900 Hz) and (tone > 1100 Hz)
Voice synthesis vocabulary
Any digits 0 through 9 (for verification of current
programming)
Test tone detect
(normally disabled) When enabled, unit disconnects on
detection of 1000 Hz tone for 1 - 300 seconds
Idle detect
(normally disabled) When enabled, unit performs switchhook
flash on detecting no activity on line for programmable period
of 1 to 99 minutes. It then looks for tone of 305 to 640 Hz for
5 seconds, then disconnects incoming and outgoing lines.
Must accept 305 < sig < 640
Must reject 300 > sig > 645
Error tone
Alternating high and low tones for 2 sec (notifies user of error
in programming or security code entry)
