Disconnect Detect Setup
The SX5e is able to detect both a PBX disconnect tone and an analog disconnect pulse. When a
PBX detects a hang-up, the SX5e must be told to also release the line. This is typically done by
either a disconnect pulse or disconnect tone, but it is PBX specific. To find out what your PBX
does, contact your PBX manufacturer or refer to your PBX technical manual.
Disconnect Tone Setup
The SX5e can be configured to detect a single PBX disconnect tone. Tone options include six-
teen standard DTMF tones (0-9, *, #, A, B, C, D), 400Hz (silence (no tone), or not disconnect
tone (off). The SX5e PBX FWT defaults to not detect a tone (off). In addition to different tone
options, thresholds and tone durations can be set. To configure the SX5e to detect a tone enter
the following command sequence.
For tones 0 - 16
Press: # * 111 * <tone> #
For tones 17, 18, 19, and 20
Press: # * 111 * <tone> * <rx threshold> * <tone duration> * <silence duration> #
HINT: When configuring the SX5e for DTMF Detection, try using DTMF D (16) first, then test
the configuration with your PBX. If that does not work, try DTMF C (15), then DTMF B (14),
etc., until you find the correct tone that your PBX sends on a disconnect.
NOTE: Your PBX must support a DTMF disconnect tone for this feature to work.
Disconnect Pulse
The SX5e will automatically detect this type of disconnection from the PBX. There is nothing
you need to do on the SX5e to enable this. A disconnect pulse from the PBX of at least 200ms
is required for proper disconnect detection.
Two-Stage Dialing Setup (GSM to Extension)
When in Extension Mode, the SX5e allows two-stage dialing so incoming GSM callers can con-
nect to an extension on the PBX. In this mode, if you call the SX5e via GSM, the SX5e will auto-
matically answer the call and present a dial tone. Since the SX5e would be connected to an
extension on a PBX, you can access any other extension on the PBX as though you where in
your office. Dial the extension number and the SX5e will connect you to that extension through
the PBX. Once in extension mode, press #
*

*
1 # from a DTMF phone connected to the
trunk connector of the SX5e - see Figure 15. The SX5e is now configured for Two-Stage Dialing.
