The Technisys 8 Channel E1/T1 Line
Rate Converter is a stand-alone
device designed to provide conversion of 8 Channels of E1 or
T1 Line Inputs to T1 or E1 line signals. The E1/T1 Line I/O
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.
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.
