station power source. Since the base station is automatically backed up by
battery power no additional back up power source is required by the hub unit.
4.6
Hub Interconnect Module
The Hub interconnect module provides the interface between the controller
module, the RF modem, fiber optic modules and the up link RF path signal
attenuators to the control circuits. It also provides user alarm interface and DC
distribution to all modules.
4.7
Controller Module
The Controller module provides the monitoring and control of the alarm and
control functions of the hub and microcell units. These alarms and controls can
be addressed and displayed by the function keys and display on the front of the
control unit. The controller also supports either a hyper terminal connection or a
optional modem. Alarms are instantly reported either via an optional modem
connection or by the base station alarm function using the relay alarm contacts on
the Hub interconnect module. Normally the two alarm relays are set up to alarm
Hub on relay 1 and Microcells on relay 2. The technician can access the control
and alarm system via the hyper terminal or optional telephone modem and
determine the actual alarm and system status.
4.8
Controller Expansion Module
The Controller Expansion Module allows for additional uplink path attenuators
for the added diversity receive paths. Since the optical loss is the same for both
of the receive paths the diversity attenuators are controlled in parallel with the
main receiver attenuators. This boardis stacked above the Controller Module and
connected with a ribbon cable.
OPTIONAL MODULES;
4.9
AC Power Supply
The optional AC power supply allows the hub unit to operate from the AC
primary power source. This option deletes the DC/DC converters.
4.10
Telco Modem
The telco modem provides the optional ability to remotely connect to the hub
control module and access system alarms and controls. This option uses the
Local Hyperterminal output and it is not available for use when this option is
selected.
4.11
Duplex, Base Station Interface
The duplex base station interface option provides the required duplexer and
cabling changes required for a single TX/RX input connection from the base
station.
4.12
Combiner Option
The combiner option provides multicarrier interface (see Figure 2.1).
