INTRODUCTION 2-1
1X 8SPLITTER 2-2
Introduction
The DRSS/E1SS product range comprises a 1:8 Splitter,
4:1 Switch and programmable 4 x 4 Router for 2048kbits/s ITU
G.703 bitstreams.
Typical applications include the distribution, monitoring and
recording of DAB & DMB Multiplex bitstreams, E1 G.703
bitstream duplication for backup or monitoring..
All DRSS/E1SS models support DAB/DMB ETI and STI
bitstreams that are compatible with ITU G.703.
The units are AC powered and supplied in 1U rackmount
cases.

Installation and Operation 2-2
1 x 8 Splitter
DRSS/E1SS Splitter provides a means of non-intrusively
monitoring or recording DAB Ensemble Transport Interface
(ETI) bitstreams without loading the original signals.
The source bitstream connection is made through one of two
BNC connectors that are hard-wired in parallel. This means
that the source bitstream passes-through the Splitter without
any in-line curcuitry or delay.
Monitoring and recording equipment can be connected or
disconnected, or power can be removed from the unit, without
disturbing the source bitstream.
Front panel LED indicators provide status display of power
and source stream input signal presence.
