Well, actually this is the work product of the "TF34" work group in
ATIS/ESIF. It defines basically two protocols, ESMI and EISI. ESMI is used
when you have what they call "mediated" access to services by a PSAP, i.e.
the PSAP desires a middle man to mediate access to various IP based services
the PSAP may have available to it. ESMI is the interface between the
mediation (RG = Response Gateway) and the PSAP.
The EISI is the other side, Service to RG, although it may be useful to
connect directly from a service to the PSAP.
I personally think ESMI is a mess. Go read it. EISI is basically a profile
of web services, and may be more useful. That's a personal opinion, and
doesn't represent the views of .
Now, in answer to the original question, yes docs are available, but because
this is ATIS, you have to buy them. There are drafts around if you look on

Good question. I noted that their effort has focused purely on NGN. While
I've heard that word thrown around, I've never actually head a good
explanation of what it is. The nearest I can tell, NGN is a walled-garden,
non-global Internet, US-centric network. It is good that they have done this
for NGN, but I doubt those standards will apply to the global Internet.
