8 Channel E1/T1 Line Rate Converter



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.

Additional Models Available
In addition to this model, Technisys also offers units for CLOCK/DATA conversion to E1/T1 Line output and E1/T1 Line Termination Clock/Data Recovery (CDR). These units, P/N 701309 & 701319 respectively, are available in the same 1U package, which includes auto-ranging AC Mains. Please contact Technisys for more details.
