! 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 2-39) 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 2-55). 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, including units that do not support
voice, since they are also affected by the use of the ACSE
protocol.
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.
