Synectix VMS Lite User Manual page 54

There are three kinds of dial modes. The correct mode must be chosen for the PBX to
work properly.
Tone: Most current PBX systems use this method where the digits are dialed as an
audio tone comprising of two tones (DTMF method). The Tone is on for 100 msec and
off for 100 msec.
Pulse: This is an older method of dialing where each digit was dialed out by making
and breaking the connection rapidly resulting in a pulse on the line. For the digit 1, one
pulse is dialed, two pulses are dialed for the digit 2 and for the digit 0, ten pulses are
transmitted.
Long tone: It is another form of DTMF signaling where the time duration for each tone
is 300 msec.
3.4.1.5 MWL parameters:
The Message Waiting Lamp (MWL) is normally available on most digital phone
instruments and some analog phones. This lamp may be made to glow on or off by
sending an appropriate string to the PBX and is usually made to flash when a mailbox-
owner gets a new message.
The 'Enable String' and 'Disable String' may contain a maximum of 16 characters. The
strings may be programmed only if the `MWL Enabled' check box is selected.
Example: 'Enable String' = '*761E'. In this case, for example, to glow the Message
Waiting Lamp of Extension 539, the Synectix VMS Lite goes off hook and dials *761539
and to put off the lamp, it dials *762539.
Valid characters - digits, *, #, p, P, e, E, h, H where, "p, p = Pause",
and "H, h = Hook-flash".
3.4.1.6 In-Band Signaling Strings
These are strings sent by PBX to inform Synectix VMS Lite about the status of the call.
There are various types of in-band strings as may be seen in the screen view. The text
box for entering In-band signaling strings accept digits, *, # and a few alphabets like p,
P, h, H, e, E, where, "p, p = Pause", "H, h = Hook-flash" and "E, e = Extension".
Wait Time For 1st Digit: This is the maximum time up to which the Synectix VMS Lite
waits after going off hook to receive the in-band strings. Enter new value in two-digit
format. The wait time value ranges from 00 to 99 where the actual wait time is equal to
the entered value multiplied by 50 milliseconds.
Default value = 0 (disabled)
