JDSUHST-3000 E1 SIM Module
Two separate receivers (RX) and transmitters (TX) allow for the simultaneous monitoring and evaluation of a wide range of alarms and errors. Different test modes with clock preferences support all of the requirements for ITU-T G.703 frame analysis, BERT, ITU-T G.821, ITU-T G.826, and ITU-T M.2100. This enables operators to validate connectivity and QoS quickly and efficiently.
E1 Pulse Shape Option
Incorrect pulse shape, due to jitter or incorrectly terminated interfaces, causes poor network performance. The Pulse Shape software option quickly assists in identifying network problems during installation, commissioning, or troubleshooting by comparing the pulsewith the ITU-T G.703 pulse mask.The software averages the received E1 pulse and automatically displays the result against the ITU-T mask.
With the Frame Relay software option, technicians can verify that frame relay service is functioning properly by testing LMI activity, PVC/DLCI status, congestion, and lost framesto validate committed information rates(CIR).
The HST-3000 can monitor transmission passively in both directions to confirm physical layer and service level results on E1 Circuits.
