Hello fellow NANOGers. Slightly offtopic, but I would greatly appreciate your suggestions. For my telecommunications engineering degree I am designing a TDM data analyzer, and I need suggestion, what you would like in an appliance like that.
Right now my idea is that it should be a transparent device that plugs in between two E1/T1/J1 devices and then connect to FastEthernet for data uplink. All data traveling between two devices is sent to central server that can accept data from one or more capture devices.
End user (i.e. NANOGer debugging a problem) has a program to connect to data acquisition server and can see decoded Q921/Q931 signaling data and to play-out what's happening in any one of voice channels. BERT tester and signal level indication with remote fault monitoring and logging would be included also. End user will have ability to record voice data with supplemental information too.
So my question to the community is what other features you would like to see in a device? And most of all - if you had a device like that would you find it useful?
All replies off list greatly appreciated. I would like to ask people to forward this email to colleagues that work with voice systems or to a voice operators group if you are a member of one.
Well, what do you presume to be entailed in "TDM?" ISDN is not necessarily implied. You could analyse E&M wink on D4 superframe. ;) Much simpler. -- Alex Balashov - Principal Evariste Systems Web : http://www.evaristesys.com/ Tel : (+1) (678) 954-0670 Direct : (+1) (678) 954-0671
