9.1. Overview
The SDA is an Ethernet hub/LAN switch that provides the SPR with DC power,
lightening protection, and Ethernet connectivity to the subscriber’s PCs/network.
The SDA connects to the SPR by a CAT-5e cable.
The SDA provides 10/100BaseT connectivity (depending on the SDA model) to the
subscriber’s PCs or network (up to four PCs depending on the SDA model).
The SDA is located inside the subscriber's premises, typically mounted on a wall or
simply placed on a desktop.
The SDA is available in six models:
! SDA-1: This is a hub that provides one 10BaseT interface (RJ-45 port) with the
subscriber’s PC and/or network (via a hub or LAN switch).
! SDA-4H: This is a hub and provides four 10BaseT ports for interfacing with the
subscriber’s PCs/network. In addition, one of the 10BaseT ports provides
crossover configuration for crossover-cable connection for interfacing with, for
example, other hubs.
! SDA-4S models: Integrated LAN switches, providing four 10/100BaseT
interfaces with the subscriber’s PCs/network.
! (standard): Standard integrated LAN switch, providing four 10/100BaseT
interfaces to the subscriber’s computers.
! SDA-4S/VL: Provides VLANs between its ports and the SPR, ensuring
privacy between users of different ports (i.e., multi-tenant VLAN security).
For example, all users connected to Port 1 do not “see” users connected to
Port 2.
! SDA-4S/1H3L: Provides a high priority port (left-most port) for VoIP
traffic.
! SDA-4S/VL/1H3L: Combines the functionality of the SDA-4S/VL and
SDA-4S/1H3L models (VLAN for each port and a high priority port for
VoIP).
