Transceiver Option Card Intercom Button (behind fan module)
Transceiver Ports (Rear)
The transceiver interconnects to the backplane using a120-pin HVDML digital connector and 8-pack RF connector, as
shown in the figure. These connections handle multiple signals including power supply communications, power amplifier
communications, fan interface, and peripheral interface. The digital connection receives alarm data and the site
controllers' TDM signals, which are used to pass reference and control data to the base radio.
Transceiver Module (Backplane Connections)
• Single Receiver Input: An RJ-45 Ethernet port on the base radio backplane is cabled to a site LAN switch for this
channel. The backplane also provides an RF connection to the transceiver for receive (Rx) path A.
• Dual Receiver Input: RJ-45Ethernet ports on the base radio backplane are cabled to corresponding ports on the site
controller backplanes (HPD). The backplane also provides RF connections to the transceiver for receive (Rx) paths A and B
(HPD and TDMA).
