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,
this parameter is not applicable and instead the Maximum
Voice Sessions parameter (see page 2-65) is used. The value of
the ACSE Maximum Voice Sessions parameter specifies the
maximum number of simultaneous ACSE 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 will 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 21.
The default value is 21.
" ACSE Number Of Retransmissions For Data – The maximum
number of times that a data packet that was not acknowledged
will be retransmitted. When the ACSE Option is enabled, this
parameter overrides the Number Of Retransmissions
parameter (see page 2-85). This parameter has no effect when
the ACSE Option is disabled. This parameter is applicable to all
units in deployment where the ACSE Option is enabled,
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.
