CABLING THE BSR
Network cabling at the Base Station depends on the devices implemented to provide the BSR with
connectivity to the provider's backhaul and power source. These devices can be one of the
following:
SDA: providing AC power and consisting of a single BSR
BSDU: providing DC power and consisting of multiple BSRs
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 CAT-5e Cable by the SDA-4S Type II IDU (or the SDA-4SDC) in the minimum configuration.
For larger configurations N* SDA-4Ss and N* BSRs are required or connection to BSDU(s).
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-to-SDA-4S connectivity is as follows:
Cable:
Straight-through CAT-5e Ethernet cable
Connectors:
o
MicroMAX: 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
Connector pinouts:
