13 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:
¾ SDA: AC/DC powered and consisting of a single BSR
¾ BSDU: AC/DC powered and consisting of multiple BSRs
Note: SFTP (Shielded Foiled Twisted Pair) CAT-5e outdoor cable is
recommended.
Note: If FM interference is discovered during installation, install a Ferrite
suppressor on the CAT-5e cable, near BSR. See Lightning and Surge
Protection. Refer to Commissioning Guide (Troubleshooting section) for
further instructions.
13.1 Connecting the BSR to the SDA-4S
The 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 CAT-5e cable.
The cable setup for MicroMAX-to-SDA-4S connectivity is as follows:
¾ Cable: Straight-through CAT-5e Ethernet cable
¾ Connectors:
• MicroMAX: DB15-to-RJ45 outdoor adapter (black color)
• SDA-4S: DB15-to-RJ45 indoor adapter (for connecting to DATA&PWR&SYNC D-type
connector)
• CAT-5e cable with 8-pin RJ-45 male connectors on either end
¾ Connector pinouts:
