c. ACSE voice calls will be terminated (no slot will be allocated for
the call).
The allowed range for the Call Aging Time parameter is 1 (no aging)
or 2-50,000 seconds. It is recommended to configure a call aging
time of at least 1200 (20 minutes).
The default value is 1800 seconds.
! 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.
! Transmit Antenna – Applicable only to single box (SU-R, SU-I/ID
and AU-I/ID) units. Displays which antennas are used for
transmission. Single box units support transmit antenna diversity
(2 antennas). During reception, a BreezeACCESS unit that is
connected to two antennas dynamically selects the antenna where
reception is optimal. In contrast, if the transmit antenna diversity is
enabled, the unit selects the antenna from which it will transmit
before the actual transmission. It usually uses the antenna last
used for successful transmission. In installations where a model
that can support antenna diversity is connected to a single antenna,
Transmit Antenna Diversity should be configured to transmit only
from that single antenna. Available selections are:
" Use Two Antennas
" Use Antenna No. 1
" Use Antenna No. 2
The default selection is Use Antenna No. 1.
! 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
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.
