9.5.3. Connecting to a VoIP Network
The SDA-4S/1H3L and SDA-4S/VL/1H3L model’s left-most RJ-45 Ethernet port
assigns high priority to VoIP trafic. This port is used to connect to the subscriber’s
VoIP network. This port assigns high priority to VoIP traffic, as opposed to the other
RJ-45 ports, which assigns lower priority.
The cable connections for connecting the
SDA-4S/1H3L and SDA-4S/VL/1H3L
models to the subscriber’s VoIP network, are as follows:
! Connector: 8-pin RJ-45 male
! Cable: straight-through or crossover
