DATA COMMUNICATION TESTER
A0300002

The A0300002 is a multi-purpose designed for commission,maintenance and troubleshooting on digital networks.It is used to carry out both framed and unframed tests on a wide variety of equipment such as primary multi-plexers,digital cross connects,automatic protection switches and circuits operating at speeds from 50bit/s to 2048kbit/s

TheA0300002 integrates 4 Data Interfaces,G.703 Co-dir 64kbit/s and G.703-2Mkbit/s Interface.Accommodations for future interfaces have also been considered. The measuring conditions can be stored in memory. An error analysis function allows histograms of either error or alarm data to be qurckly and easily displayed.In addition,it has been made light-weight and compact.The analyzer is portable so that it can be used on site for maintenance operations.

in Built-in interfaces - DATA COMMUNICATION TESTER Built

• V series data interface The A0300002 includes following interfaces:V.24,V.35,V.11,X.21.
  The instrument can transmit synchronous and asynchronous on each interface.It can be configured as a DTE or a DCE(by adaptor).
• G.703 Co-dir 64kbit/s Interface
• G.703-2048kbit/s

The A0300002 includes framed and unframed test on G.703-2048kbit/s interface. The A0300002 can be used for offline test of primary multiplexers on G.703-2M unframed interface or online test on G703-2M framed.The A0300002 generates and monitors PCM30,PCM30 CRC,PCM31 and PCM31 CRC frame steuctures on G.703-2Mbit/s.
