Nothing to do with Logica's SMS stuff. At a trivial level, SS7 is the
control protocol (and associated connectivity) used to interconnect
telco switches with other telco switches and other important bits of a
telco network (eg a Home Location Register in a mobile network) and to
set up and clear down telephone calls. It also does a whole lot more
but that'll do for now; if you need more there's a Wikipedia article
(plus see below).

The DEC SS7 product provided a set of high level APIs to this kind of
thing, and there was also associated rather special comms hardware. At
various times it was available on VMS, OSF and NT. There wouldn't be
many DEC SS7 customers but in the past they'd likely be well known
players in the industry and be likely to have corporate account
managers in DEC.

I have the vaguest of vague recollections that the product was at one
time renamed IN7 (for Intelligent Network 7). An IN7 SPD from 2001
exists at http://h18006.www1.hp.com/info/SP3419/SP3419PF.PDF

HP had a (competing?) SS7 product, their OpenCall SS7 Platform. The HP
equivalent of the DTJ has an article on the subject:

If there's still an HP corporate business unit focusing on the telco
sector (or if the DEC folks in sunny Sofia Antipolis still exist) they
should have definitive answers.
