BreezeACCESS Version 4.3 System Manual
 Maximum Voice Sessions – Applicable only for an AU that provides
services to Subscriber Units with voice capabilities. When the ACSE
voice scheduler option is enabled, this parameter is not applicable
and instead the Maximum ACSE Voice Sessions parameter is
used. The value of the Maximum Voice Sessions parameter
specifies the maximum number of simultaneous voice sessions that
can be conducted by the SUs associated with this AU. If the number
of active voice sessions reaches this number, any additional SU
trying to initiate a voice session shall not get a dial tone. As this
value increases, voice quality may deteriorate as more users share
the same bandwidth for voice sessions.
The selection range is from 0 to 50.
The default value is 12.
 Receive Attenuation Control (SU-A/E units) – Displays the
current attenuation introduced into the receiver circuits and allows
entry of a different attenuation value.
The available Receive Attenuation values are 0 dB (no attenuation),
10 dB and 25 dB. The effect of inserting such attenuation in the
receive circuit is equivalent to reducing the level of the received
signal (including both signal and noise) by 2 dB when selecting 10
dB attenuation and 12 dB when selecting 25 dB attenuation.
The default is 0 dB.
 ACSE Parameters – The ACSE (Adaptive Circuit Switched
Emulation) Voice Scheduler is a proprietary enhanced air protocol
that provides guaranteed delay and jitter properties for voice
sessions by reserving specific time slots for each active telephone
call. The ACSE Voice Scheduler allows the delivery of high quality
voice, while maintaining the inherent efficiency of statistically
multiplexed packet based networks. If the ACSE Voice Scheduler is
enabled, an AU can support a higher number of good quality voice
sessions. The ACSE Voice Scheduler feature does not affect voice
sessions generated by external equipment and routed via the
Ethernet port of the Subscriber Unit.
 ACSE Option – Applicable only for an AU that provides services
to Subscriber Units with voice capabilities. To enable/disable
the ACSE Voice Scheduler protocol. The AU controls the
operation of all the SUs it serves according to the configured
ACSE Option.
The default is Disable.
 Maximum ACSE Voice Sessions – Applicable only for an AU
that provides services to Subscriber Units with voice
capabilities. When the ACSE voice scheduler option is disabled,
NOTE:
A voice session is defined as a voice connection between an SU and an AU. A
session between two SUs that are served by the same AU is counted as two voice
sessions.
