A. Ring Trip Interface
1. Standard - Any ringing C.O. line or analog PABX/KSU station will be answered after the programmed ring delay,
given the announcement and released. The DVA-500A is then immediately ready to answer the next incoming
call.
2. Repeat Announcement Option - The announcement may be programmed to play up to 99 times. The
announcement will repeat, up to the programmed value, or until the caller hangs up and a CPC signal from the
C.O. is detected. Callers that do not hang up may be transferred (see below). When in programming, enter the
repeat announcement value 01 (plays once) to 99 followed by #44.
3. Transfer Option - A ringing C.O. line will be answered after the programmed ring delay, given the announce-
ment and then transferred to another extension. This option may only be used with analog PABX/KSU, OPX
station or Centrex C.O. lines with hook switch flash - blind transfer capabilities. This means a line that a "2500"
set telephone can hookswitch flash and dial an extension, but does not require that extension to answer before
releasing the call. When in programming, enter the extension number to be transferred to (up to 16 digits)
followed by #00. To remove the transfer option simply enter #00 without any previous (extension) numbers.
B. Four Wire E & M
The 600 OHM E & M jack provides a 600 ohm "Dry" output. Refer to E & M protocol settings and timing on pages 3
- 4, and the PABX table on pages 5 - 6 for proper operation.
