1.7.6
Foreign Alarm Interface
This provisioning option provides serial alarm/status reporting for the
Telemetry Byte Oriented Serial (TBOS) protocol. A wire-wrap adapter is pro-
vided to mate to connector J305 on the backplane.
1.7.7
Relay Interface Option
The optional AE-27AF Relay Interface unit provides relay closure indica-
tions of radio alarms and status. The relay interface also provides up to 16
station alarm inputs and six relay closure control outputs.
1.7.8
Extended Link Monitor Channel
ELMC is standard and performance monitoring, alarm and status informa-
tion, and remote controls are accessible through the ELMC channel, inde-
pendent of network management interfaces.
Optional remote provisioning and downloading capability is provided via an
ELMC option key that is mounted on the controller module.
1.7.9
Automatic Transmitter Power Control Provisioning Option
Automatic Transmitter Power Control (ATPC) is a standard feature that can
be enabled or disabled using the USI provisioning screens. When ATPC is
disabled, transmitter power is fixed at the recommended maximum level.
When ATPC is enabled, transmitter power may be reduced up to 10 dB from
the maximum power level when the far end RSL is above a minimum level.
When ATPC is enabled with timeout, transmitter ATPC activity is limited to
a maximum time without returning to minimum transmit power. After five
minutes of activity, the transmit power is forced to minimum until the far
end RSL returns to normal levels.
1.7.10
Service Channels Provisioning Options
The MDR-8000 provides a 256 kb/s auxiliary channel for servicing the radio.
This is an overhead channel and is independent of the traffic channels. The
256 kb/s service channel contains four 64 kb/s service channels. Three of the
four 64 kb/s channels (Service Channel 1, 2, and 3) can be provisioned on the
USI for a specific use. Service channel 4 is dedicated to radio commands and
ELMC. Service channel 4 is not provisionable. Only 16 kb/s out of the 64 kb/
s in this channel are used.
Service channels at both ends of a hop (and end-to-end in a link)
must be provisioned the same.
