Hi AZeemeri,
Thanks for your reply. It turns out that the tap is missing also so I guess we'll have to try and get hold of one of those from somewhere as well.
As far as support goes, I think it is covered - the analyser belongs to Cable and Wireless who are a telco based in the UK and is one of several that the company own. Unfortunately this one seems to be the only HSSI Sniffer they have that I can find and is obviously unusable without the external bits.
Anyway - enough whining!! Thanks for you help & a Happy New Year.
