The Technisys 8 Channel E1/T1 Converter is
a stand-alone device designed to provide conversion of 4 Channels
of NRZ Clock and Data to E1 or T1 Line
Outputs and 4 channels of Line input to Clock/Data (CDR)
pairs. The NRZ differential I/O are via
RJ-45 connectors,
and
the
E1/T1
Line I/O are via Concentric Twinax connectors. Clock and Data
validity and Line LOCK for each channel is indicated by 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 selectivelyt invert
the 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. Yellow LEDs
indicate the pattern selected. 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.
