The Technisys 8 Channel E1/T1 CDR is a stand-alone device
designed to provide conversion of 8 Channels of E1 or T1 Line
Inputs to recovered Clock/Data pairs at NRZ levels. The NRZ
differential outputs are via RJ-45 connectors, and the E1/T1
Line inputs are via Concentric Twinax connectors. 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. All channels operate
at the same rate. Front panel switches provide the ability
to select DECODING 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.
Additional Models Available
Ina addition to this model, Technisys also offers units for CLOCK/DATA
conversion to E1/T1 Line output and E1/T1 Line Rate Conversion. These
units, P/N 701309 & 701321 respectively, are available in the same
1U package, which includes auto-ranging AC Mains. Please contact Technisys
