EZ VMS Lite
Each complete string consists of 12 digits where each value is entered as 3-digit number
in the range 001 to 255. Alphabets and special character are not allowed. The Cadence
string consists of 1st Cycle - ON, 1st Cycle - OFF, 2nd Cycle - ON, Busy and 2nd Cycle -
OFF. Hence a cadence string of 015-010-015-040 corresponds to a cadence-timing
pattern of 0.50-0.33-0.50-1.32 seconds on-off-on-off pattern.
Busy: Typical Busy cadence pattern = “016 015 016 015” corresponding to a 500 msec
On-Off-On-Off pattern.
Invalid: Typical Invalid or Reorder cadence pattern = “007 008 007 008” corresponding
to a 250 msec On-Off-On-Off pattern.
Call Progress value for last call: The 12 digit string for the cadence values detected for
the last call handled by it is displayed here. This is very useful in trouble shooting or
setting up the
EZ VMS Lite to interface with a new PBX.
Wait Time Before Call Progress: Some times it is required to start the call progress
detection after a short delay. For example, quite often, the PBX gives out a transfer tone
immediately after a call is transferred and this interferes with the cadence detection if
the detection is started immediately after the call is transferred.
You may program the delay period here and the EZ VMS Lite starts the cadence
detection only after this delay period has elapsed.
Enter the new value in two-digit format, which are in multiples of 40 milliseconds. The
value ranges from 00 to 99 giving a maximum delay of 400 msec. Default value is 0.
