1. No transceivers installed. This configuration allows customers to
install two existing transceivers in the empty chassis to create a
Redundant Station.
2. One transceiver installed. Similarly, this configuration allows cus-
tomers to install an existing transceiver to create a Redundant Sta-
tion.
3. Two transceivers installed. This configuration provides an immedi-
ately usable Redundant Station for new customers, or for existing
customers who wish to add a Redundant Station without installing
existing transceivers.
2.3 Antenna Port Configurations
The Redundant Transceiver Chassis can be configured with a single
antenna, or with two antennas for continued operation if the primary
antenna becomes damaged or is otherwise inoperative.
1. Single antenna port. The port is automatically connected to the
active transceiver by an internal relay.
2. Two antenna ports. Each port is connected to one of the transceivers
and to separate station antennas.
2.4 Model Configuration Codes
The configuration details of the Redundant Transceiver Chassis (as
shipped from the factory) can be quickly determined from the model
number label attached to the outside of the chassis. Figure 2 shows the
significance of the model number characters printed on the label.
