Using the SDA-4S Type II or SDA-4S/VL Type II
The SDA-4S Type II or SDA-4S/VL Type II adapters (referred hereafter as SDA-4S) provide one
four RJ-45 (10/100BaseT) ports for interfacing with the subscriber's LAN network. The
difference between these two adapters is that the SDA-4S/VL supports VLAN functionality at the
ports.
The ports of the SDA-4S models 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-5 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 5 Ethernet cable
Connectors: 8-pin RJ-45 at both ends
Connector pinouts:
