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.
OPTIONAL MODULES;
4.8 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.
4.9 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.
4.10 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.
4.11 Combiner Option
The combiner option provides multicarrier interface (see Figure 2.1).
4.12 Cross Band Operation Option
The cross band operation option provides the triplexing, cabling and hardware
changes for the combining of PCS 1.9 MHz signals with the Cellular 800 MHz
signals and the RF modem signal to a common input/output to/from the fiber
optic module. (Reference Figures 2.2 and 2.4).
4.13 Wave Division Multiplexer (WDM) Option
The WDM module allows the 1550 nm down link and the 1310 nm up link
optical signals to be duplexed onto a single fiber optic cable. The WDM mounts
externally at the Hub location, on a 19-inch rack mountable tray assembly. One
WDM module is required for each optical transceiver the Hub is equipped with.
Each Microcell will also require a WDM option which mounts internally in the
unit.
4.14 Optical Expansion Module
The fiber optical expansion module is required at the Hub for each Microcell unit
added to the EkoCel Fiber Optic Microcell System and may be expanded up to
a total of four per hub.
