10.4. Connecting to the SDA
The SPR’s power supply and connectivity to the subscriber’s Ethernet network is
provided by the SDA. To connect the SPR to the SDA, you need to connect the
SPR’s 15-pin D-type port to the SDA’s 15-pin D-type port using a CAT-5 cable.
The SPR-to-SDA cable setup is as follows:
Cable: straight-through 10Base-T Ethernet UTP 4 Pair CAT-5e 24 AWG
outdoor type (100 meters)
Connectors:
SPR side: 15-pin D-type male (only 8 pins are used)
