Vmux-210 Ver. 1.1 Frequently Asked Questions 6-23
1100 Hz (CNG) will cause the Vmux-210 to switch into fax-relay mode
(if fax relay is enabled).
2100 Hz (fax/modem CED) will cause the Vmux-210 to switch into VBD
(if modem relay is enabled).
Important: The above tones may be detected in the range of +/- 50 Hz
(e.g. 1080 Hz can be detected as 1100 Hz). Therefore when testing voice
frequency across Vmux-210, you should AVOID the following frequency
ranges: 1050-1150 Hz, 1950-2150 Hz.
Q: Pressing the Flash button of the telephone set connected to the FXS port of
the Vmux-210 does not result in the expected function of the PBX/PSTN.
What is the problem?
A: The problem could be related to the Vmux-210 FXS ports setting.
The Flash signal is actually a short on-hook signal, used for many kinds of
PBX/PSTN features. For example, in the call-waiting feature, during an
ongoing conversation, pressing the flash will switch the subscriber to a
waiting call.
Another example is the conference call. A subscriber engaged in a call can
press the Flash button in order to put his remote party on hold and to call a
second remote party. Once the second remote party answers the call,
pressing the flash again will create a bridge enabling the three parties to have
a conference call.
You can define the period of an On-hook/Off-hook action that will be
recognized by the Vmux-210 as a Flash.
From the Main Menu select Configuration -> Physical Ports -> Analog ->
Timeouts
The following screen appears:
Timeouts
---------
1. Ring Timeout (sec)[60 - 600]... (120)
2. On hook duration in Flash (msec)[10 - 2000]... (700)
Option number 2 is the on-hook duration for the Flash. The default value
is 700 msec, meaning that during a call, if an on-hook state lasts between
0 and 700 msec, it will be handled as a Flash and the call will not be
disconnected.
Q: What is the meaning of the fragmentation function in the Vmux-210?
A: By default, voice packets get priority over data packets arriving from the LAN
user port. The transmission of frames through the main link (E1/T1/Serial
only) is made in accordance with their priority. However, the prioritization
mechanism cannot ensure a low transmission delay in case a high-priority
packet (voice) arrives after the transmission of a long, lower priority packet
(data) has begun.
