Disconnect Detect Setup
The SX5 is able to detect both a PBX disconnect tone and an analog disconnect pulse. When a
PBX detects a hang-up, the SX5 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 SX5 can be configured to detect a single PBX disconnect tone. Tone options include sixteen
standard DTMF tones (0-9, *, #, A, B, C, D), 400Hz, 440Hz, silence, or no disconnect tone (off).
The SX5 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 SX5 to detect a tone enter the follow-
ing 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 SX5 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 SX5 will automatically detect this type of disconnection from the PBX. There is nothing you
need to do on the SX5 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 SX5 allows two-stage dialing so incoming GSM callers can connect
to an extension on the PBX. In this mode, if you call the SX5 via GSM, the SX5 will automatically
answer the call and present a dial tone. Since the SX5 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 SX5 will connect you to that extension through the PBX. Once in
extension mode, press
#
*
109
*
1 #
from a DTMF phone connected to the trunk connector of
the SX5
- see Figure 15.
The SX5 is now configured for Two-Stage Dialing.
