INTRODUCTION 2-1
AVAILABLE VERSIONS 2-2
Introduction
E1DT E1 Splitter/Buffer provides a means of monitoring and
capturing traffic flowing in both directions of a 2Mbits/s E1/PRI
(G.703/G.704) communications link.
The line connections are made through two RJ-45 connectors
that are hard-wired in parallel. All line activity is passed-
through the Splitter/Buffer. Monitoring and recording
equipment can be connected or disconnected without
disturbing the line.
Line signals are split and fed into high-impedance buffers that
load the line signals by less than 0.1dB. Low-impedance
outputs allow the monitoring equipment to be located up to
50m away from the line connection.
The design ensures that there is no interruption of the line
signals when the Splitter/Buffer is unpowered.
LED indicators are provided for power (green) and signal
(amber) presence at each monitor output connector.
E1DT operates from +6v to +12V DC power. UK and
European AC power adapters are available as options.

Available Versions
Two versions of E1DT are available.
E1DT-ASSY-0058
Provides the monitor outputs on a single RJ-45 connector
(Stream A pins 1/2 and 4/5) for use with devices that
monitor both Tx and RX on the same input connector.
This version is not compatible with SomerData PC-VDR
E1/PRI Recorders and R2D3 Data Capture Cards.
E1DT-ASSY-0059
Provides the monitor outputs on two RJ-45 connectors
(pins 1 & 2) for use with devices that monitor Tx and RX on
two input connectors.
This version is compatible with SomerData PC-VDR
E1/PRI Recorders and R2D3 Data Capture Cards.

3. POWER CONNECTION
In this Section
POWER SOURCE 3-1
Power Source
Recommended power source is a standard 6V, 9V or 12V
regulated 100mA power supply with 2.1 mm (centre positive) low
voltage connector.
An unregulated power supply can be used provided that the input
voltage to E1DT does not exceed 12V.
UK and European AC power adapters are available as options.
+6 Volts DC to +12 Volts DC

INTRODUCTION 4-1
INPUT/OUTPUT CONNECTOR PINOUTS 4-2
Introduction
Both Tx and Rx monitor outputs are on a single RJ-45 connector
(Stream A).
E1DT-ASSY-0058 should not be used with a SomerData PC-VDR
E1/PRI Recorder or R2D3 E1/PRI Data Capture Card
(see E1DT-ASSY-0059).
Connections should be made using standard CAT5 (1:1) cable.

INPUT/OUTPUT CONNECTOR PINOUTS 5-2
Introduction
Tx and Rx monitor outputs are on two RJ-45 connectors.
Stream A for the Line Tx bitstream and Steam B for the Line Rx
bitstream.
Both bitstreams appear on the Tx pins of the monitor output
connectors for compatibility with with SomerData PC-VDR E1/PRI
Recorders and R2D3 E1/PRI Data Capture Cards.
Connections should be made using standard CAT5 (1:1) cable.
