Protected Network Station; Mds™ Master Station Compatibility - GE MDS SD Series Technical Manual

Protected Network Station

The transceiver is available in a protected network configuration, known as the SDxP (Figure 4),
where x denotes the particular model of SD transceiver installed inside the chassis (i.e., SD1, 2,
4, 9, etc.).
The SDxP is a tabletop or rack-mount unit designed to hold two transceivers, two power sup-
plies, and a switchover logic board that automatically selects between transceiver A or B as the
active unit. Manual selection may also be made using a front panel switch.

With two transceivers and two power supplies installed, the unit continues to communicate even
if a failure occurs in one of the transceivers, or its associated power supply. This capability is
important in critical applications where uninterrupted service is required. Refer to publication
05-4161A01 for detailed information on this product.
2.6 MDS™ Master Station Compatibility
Figure 5. MDS™ Master Station
In order to keep up with advancing technology, the MDS™ Master Station has been created to be
a drop-in ready replacement for earlier MDS x790 Master Stations and provides backwards
compatibility with x710 radio systems. The Master Station runs on the Orbit platform to provide
highly secure and robust operations that far succeed legacy MDS products.
The Master Station is available on multiple frequencies and bands with more to be added every
day. To see which models are currently available, as well as more detailed information about the
MDS™ Master Station, visit the GEMDS website at www.gemds.com.
