He added, “When traditional T1 E1 circuits from telco are not available, or too expensive, operators may resort to satellite or microwave transmission. Ethernet backhaul may also be considered. Each technology has differing delays, error performance, and reliability characteristics. A network operator must be equipped with proper tools to monitor, troubleshoot, and assess various types of backhaul options:
* Assessing performance of legacy transmission (T1 E1) or Ethernet backhaul requires test tools that can measure clock accuracy, clock jitter, bit error rate, packet jitter, packet loss, round trip delay and throughput. All of these functions in a single test set is preferable
* If the same tool can also be used for installation, maintenance, and performance monitoring, so much the better.
Mr. Kulkarni further added, “GL provides various testing solutions to monitor and test backhaul networks. Our test gear helps test backhaul no matter what the media; are portable, hand-held, or PC based, and is used successfully by customers world-wide to monitor and troubleshoot deployed networks”.
