The Technisys 8 Channel NRZ to E1/T1 Converter
is a stand-alone device designed to provide convesion of 8
Channels of NRZ Clock and Data to E1 or T1 Line Ouputs. The
NRZ differential inputs are via RJ-45 connectores, and the
E1/T1 line outputs are via concentric twinax connectors. Clock
and Data validity for each channel is indicated by a front
panel LEDs. The line interface (E1/T1) and corresponding data
rate (2.048MHz/1.544MHz) are selected by a front panel switch.
Front panel switches provide the ability to selectively invert
the incoming data and clock for each channel.
The unit also contains a Test Pattern Generator, which provides R3, R7,
R15, R20 PRBS patterns, and All Ones pattern. Selection is made via front
panel 5-position rotary switch. When the Test Generator FRAMED Mode is
selected, the PRBS patterns are mapped into the payload of E1 or T1 frames,
as selected by the T1/E1 System Rate Switch. Output from the Test Generator
may be directly connected to the NRZ inputs via a straight-through cable
with RJ-45 connectors.

RECOVERY (CDR) from E1/T1 Line input and E1/T1 Line
