The ET2035 is a part of the our range of pocket size testers specifically designed aiding the installation, commissioning and fault finding on high speed V.35 circuits.
The product incorporates many features that allow a user to quickly identify operational problems. When plugged into a V35 interface the unit can measure either the transmit or receive clock frequency to an accuracy of 0.5KHz up to a frequency of 2048KHz. For systems where an external clock is required, the optional ET2036 module can be plugged into the 2035 to generate a selection of clock speeds from 64K – 2048K in steps of 64K. The 2036 module is powered from the 2035 tester and provides both DTE and DCE interfaces to attached equipment.
The unit incorporates a standard PRP15 test pattern generator and checker and is down line compatible with the ET2048 G.703/G.704 diagnostic test set and the ET2021 X21 tester. In this mode the unit can detect and display transmission errors but also it is capable of identifying wiring and system problems. Phasing errors due to the inversion of the clock signals with respect to the data are identified by the ET2035, as is the receipt of an inverted PRP15 test pattern. To aid in identifying transmission problems, the ET2035 can be set to transmit either continuous 1 or 0 data bits.
In order to identify problems (especially protocol issues) due to excess propagation transmission delays, the 2035 can measure continuously the time it takes to return data back from a distant location and display the time in milliseconds (mS). The 2035 can accommodate transmission over two satellite links within the same circuit.
