CABLING THE BSR
Connecting the BSR to the SDA-4S
he SDA-4S provides -48 VDC power to the BSR as well as the Fast Ethernet interface between the
BSR and the provider's backhaul network. The outdoor Base Station Radio and Modem are powered
over a CAT5e Cable by the SDA-4S Type II IDU in the minimum configuration. For larger
configurations N* SDA-4Ss and N* BSRs are required.
The BSR interfaces with the subscriber's Ethernet network through the SDA-4S. To connect the BSR
to the SDA-4S, you need to connect the BSR's 15-pin D-type port to the SDA-4S's 15-pin D-type
port using a CAT-5e cable.
The cable setup for MicroMAX-SOC-to-SDA-4S connectivity is as follows:
Cable: Straight-through CAT 5e Ethernet cable
Connectors:
o
MicroMAX-SOC: DB15-to-RJ45 outdoor adapter
o
SDA-4S: DB15-to-RJ45 indoor adapter (for connecting to DATA&PWR&SYNC D-type
connector)
o
CAT 5e cable with 8-pin RJ-45 male connectors on either end
