The SPR is mounted outside on an external wall or on a pole. The SPR connects to
the SDA by a standard CAT-5 cable.
1.4.1.2. Subscriber Data Adapter (SDA)
The SDA is a switch or hub (depending on model), providing the SPR with -48
VDC power supply, lightening protection, and 10/100BaseT interface to the
subscriber's PCs/network.
The SDA is installed indoors and can be mounted on a wall or simply placed on a
desktop. The SDA connects to the SPR by a standard CAT-5 cable.
The SDA is available in the following models:
SDA-1: hub providing one 10BaseT interface with the subscriber's computer (or
LAN network if connected to another hub or a switch).
SDA-1/DC: adapter that provides Ethernet (one 10BaseT) and regulated
–48 VDC power to the SPR. This model can be powered from a voltage of 10 –
52 VDC (e.g. from a solar panel that typically provides 12 VDC). This model is
typically implemented in mobile wireless applications, e.g. in a car or truck.
(This model can also be implemented at a Base Station with a BSR.)
SDA-4H: hub providing four 10BaseT interfaces with the subscriber's
computers and/or networks. One of the 10BaseT ports provides crossover
cabling for interfacing with another hub or LAN switch. Alternatively, it may be
connected to another PC via a crossed Ethernet cable.
