Note: The wire color-coding described in the table is Airspan's standard for wire color-
coding. However, if you implement your company's wire color-coding scheme, ensure that the
wires are paired and twisted according to pin functions listed in the table above (e.g. Rx+
with Rx-).
Note: The maximum CAT 5e cable length for ODU/IDU connectivity is 100 meters.
To connect the BSR to the SDA-4S:
1. Connect the 15-pin D-type male connector, at one end of the CAT-5e cable, to the BSR's
15-pin D-type port labeled DATA&PWR&SYNC.
2. Connect the 15-pin D-type male connector, at the other end of the CAT-5e cable, to the
SDA-4S's 15-pin D-type port.
SDA-4S Type II
Using the SDA-4S Type II
The SDA-4S Type II (or the SDA-4SDC) provides one to four RJ-45 (100BaseT) ports for
interfacing with the subscriber's LAN network.
The ports of the SDA-4S model support Auto Negotiation, allowing automatic configuration for
the highest possible speed link (10BaseT or 100BaseT), and Full Duplex or Half Duplex mode.
In other words, the speed of the connected device (e.g. PC) determines the speed at which
packets are transmitted through the specific port. For example, if the device to which the port
is connected is running at 100 Mbps, the port connection will transmit packets at 100 Mbps.
Conversely, if the device to which the port is connected is running at 10 Mbps, the port
connection will transmit packets at 10 Mbps
In addition, the SDA-4S ports support MDI/MDI-X automatic crossover, allowing connection to
straight-through or crossover CAT-5e cables. Therefore, these ports can be connected to either
a hub (i.e. using crossover cables) or a PC (i.e. using straight-through cables).
The cable setup for SDA-4S LAN connectivity is as follows:
Cable: Straight-through (e.g. when connecting to PC) or crossover (i.e. when connecting to
a hub) CAT-5e Ethernet cable
Connectors: 8-pin RJ-45 at both ends
Connector pinouts:
o Straight-through cable (e.g. connecting to a PC)
