GL Communications is rather gushing about its LightSpeed 1000 product and claims it can do a lot of things.

The hardware platform (PCIe Card and USB Pod) is capable of OC-3/12 and STM-1/4 wire-speed processing on quad optical ports for functions such as wire-speed recording and wire-speed playback of unchannelised and channelised ATM, PoS, and RAW Traffic.
Two of its four ports are designed for SONET/SDH unchannelised and unframed data.
The other two ports are meant for SONET/SDH channelized data of carrying many independent unframed/framed T1, E1, T3 and E3 streams.
It also comes with software for overall monitoring, BERT, emulation and protocol analysis and GL says its price tag “compares very favourably” with similar test instruments at three times the price.
Its main advantage, GL says, is that any of the T1/E1 or DS0 test requirements can be met without resorting to electrical access. www.gl.com
