we need a document describing the INS1500 ISDN PRI standard in Japan
(used by NTT). Especially the Q931 portion of it. We have the ISDN
that describes Lucent 5ESS and ATT 4ESS switches and need to
differentiate the INS1500 by NTT from these switches. |

Hello spedia:
Thanks for the challenging question.
I've been able to find three promising documents that might be a start
to what you're looking for. However, I'm unfamiliar with this
technology, so I'm not sure whether any of them are on the right
track. If you would please have a look at the three and tell me if any
of them are worth pursuing further, that would be a lot of help.
1. Cause and Location Codes

Quote: "INS1500: NTT's INS1500 is an ISDN Primary Rate Interface
(PRI). It consists of 23 B channels (Bearer channels) for data
transmission and one D channel (Delta or Data channel). Unlike INS64,
INS1500 requires a fiber optic connection between the customer and
NTT. INS1500 can be boosted up to 24 B channels by using a separate
INS64 line for the D channel. The 23 B channels can be multiplexed
together for a maximum data rate of 1.5 Mbps."
I look forward to your reply.

The provided answers are just generic material (mainly cisco tech
support documentation that has already been researched and does not
contain the information required).
We need the actual RFC or other technical document (ITU, TTC or other
Telco organization document that describes the SIGNALING used for
Q.931 INS1500). Generic mesages in proprietory products (such as
Cisco) are not of interest to us.

Hi spedia:
Thanks for the clarification. I was unable to find anything that fits
your description on the Web. Perhaps another one of our researchers
will have better luck.

Hello Spedia,
I marvel at people like yourself who actually understand the technical
nuts and bolts of modern telecommunications. I don't! And while I
think I've found the document you need, I hesitate to post it because
my understanding in this area is razor thin.
However...it sounds like you're looking for the signaling specs for a
Telco Switch with a PRI ISDN Q.931 Interface. If that's the case,
then I can send you directly to the link on the web where you can buy
the 344-page document that specifies the ISDN user to network Q931
interface for call control. The document itself costs about $100,
beyond anything you'll spend here at Google Answers.
An important caveat though, is this. I haven't looked at the document
myself to verify that it is, in fact, the standard for the INS1500
used by NTT (and even if I *did* have a chance to look at it, I'm
still not sure I could glean the answer). However, from what you
describe, this seems to be the Q931 piece of what you're looking for.
I'm sorry to leave things so iffy. If you would like me to post the
link as an answer, let me know. Or if you have an alternative
suggestion, let me know that as well.

OK. The purposes of the whole procedure is not to issue a generic
search via web (we have gone through this process already with no
luck). Nothing that a search engine can return as a result in the top
30 lists will be capable of answering this question.
The problem comes from the fact that the INS1500 ISDN/PRI standard is
Japanese and it lacks English documentation. Our efforts could not
produce a single good reference URL, that will help us allow our ISDN
router to interface to INS1500 equipment.
If you are referring to these web sites:
http://www.ttc.or.jp
http://www.itu.int/home/index.html
we have been all over them already. I need a document that will
describe the Q.931 specs of INS1500 ISDN/PRI equipment used by NTT
(Japanese Telco). I do not need a generic Q.931 reference because the
chances are we already have it.

Hello again. Like I said, I'm still on the job.
I have found something, but the question is, do you have this already,
or is it something new (and if new, is it something of interest?).
There are some documents that describe technical standards in Japan
that are written in English. They are prepared by a group called the
TTC, and from what I can tell, the full standards are in Japanese,
while more often than not, only comrehensive summaries are in English
(there are exceptions though, and some full standards appear to be
available in English as well). These follow a coding/numbering
convention similar to the ITU so that the standard JT-Q931 is the
Japanese corollary to Q931 as established by ITU.
A piece of the JT-Q931 standard is below.
"JT-Q931 ISDN User-Network Interface Layer 3 Specification for
@@@@Basic Call Control
1. Relations with international standards
This Standard is based on the ITU-T Recommendation Q.931 approved in
the SG11
meeting( March 1993) and the changes approved in the SG11 meeting(May
1998).
2. Summary of differences from the international recommendations
(1) Of the optional items in ITU-T Recommendation Q.931, the following
have been selected as the TTC standards. (Corresponding Chapter and
Section numbers are shown in parentheses).
(A) Because the support of 2 octets is always essential as the length
of a Call Reference, a 2-octet Call Reference is regarded as the
unified standard. A 1- or 2-octet Call Reference for the primary-rate
interface, however, is specified to be sent as a network option.
(B) As the sending procedure of the Called Party Number from the
calling party, en bloc sending is considered as a standard and the
overlap sending is non-standard.
Because the en bloc sending procedure as the basic procedure shares
the functions of the overlap sending procedure, the two procedures are
unified into one; namely, the en bloc sending procedure.
(5.1.3)
(C) As the incoming call procedure to the called party, the en bloc
procedure is considered as a standard, while the overlap procedure is
non-standard.
The en bloc incoming call procedure is viable in Japan, since the
fixed numbering plan is employed there. In addition, the en bloc
incoming call procedure as the basic procedure shares all the
functions of the overlap procedure. Therefore, the en bloc incoming
call procedure is considered as a standard.
(D)The incoming call procedure over a data link with SAPI=16 on the
D-channel for packet-mode is regarded as non-standard.(6.2.2.3) only
the procedures making use of the SAPI=0 data link are regarded as
standard, while those making use of the SAPI=16 link are considered to
be provisional and their necessity can not be identified. As
information, it is specified in the ITU-T
Recommendation Q.931 that terminals implemented with the procedures
with the SAPI=16 must be implemented with also the procedures with the
SAPI=0 to guarantee terminal portability .
(2) TTC has analyzed the optional items in ITU-T Recommendation Q.931
and they are summarized, except for (1) above, in Table 1 of this
Summary."
And so on. The full document is 3-pages, and downloadable.
There are many other English-language standards documents available
from TTC. They are organized in the following categories:
Inter-network Transmission
ISDN Inter-network Signalling
Packet / Frame Relay
Mobile Communications
ISDN User-Network Interface
B-ISDN
PBX
LAN
MHS / OSI
Telematics
Infrared Communications
Network Management
Voice Coding
Video Coding / AV Communications
I am simply not competent to tell you which ones are most relevant to
your needs.
Is this on the right track? Let me know, so I can investigate more
fully.
Thanks.

As I already mentioned the TTC site is already explored. Look several
passages above. We have this already. I do not know how this whole
Google process work. I am not that interested in finding someone to
search the web for us, as I am interested in finding someone with
experience in the industry who can provide is with the appropriate
document or its source.

The process works like this. A large number of researchers with a
whole host of different experiences and backgrounds see your question.
Anyone can try to respond by (1) making use of their own knowledge
(2) searching for information, or (3) finding the right people to get
an answer.
I can't do (1), I've tried (2) with no success yet, and am now looking
into (3).
If no one comes up with an answer, then you've paid only a fifty cents
listing fee -- not a bad investment, if you ask me.

Hello Spedia,
No, I haven't forgotten about you. I have received some information
in regard to my many inquiries about INS1500 standards, and I have a
link to detailed technical specs, in English.
The specs reference INS-Net1500 from NTT, which *I believe* to be one
and the same as INS1500, but I have been unable yet to confirm this.
The intro to the document says this:
"This technical reference document explains about the INS Net and the
interface to the telecommunication machinery connected with the INS
Net and offers technical information that would be a reference in
designing telecommunication machinery.
Nippon Telegraph and Telephone Corpration (NTT) does not guarantee the
telecommunication quality by the contents of this document.
Conditions that terminal equipment should provide are established in
the
regulation about technical condition of a terminal connection on
general
telecommunication service, and this document includes a part of
contents.
INS Net offers “INS Net 64„ (basic interface) service that can use two
64kbit/s
information channels and a 16kbit/s signaling channel, and, besides,
it also offers “INS Net 1500„ (primary rate interface) service that
can use higher bitrate channels such as 384kbit/s and 1536kbit/s. Both
of them may be available the circuit-mode and packetmode services."

that will become available at some future date:

I've included detailed table of contents for Vol. 3 below, so you can
see what it looks like. If this looks like a possibility to you, do
you want me to post it now as an answer, or wait until I can confirm
that INS1500 and INS Net1500 are one and the same?
Let me know.

Hi:
This looks like something that we may need. However, we need the
actual documentation not just a URL link to explore. Can you provide
the actual documentation (not just the index).

Hello Spedia,
Thanks for getting back to me, but I didn't fully understand your
comment that you "need the actual documentation, not just a link..."
The link I mentioned HAS all the documentation...it includes several
hundred pages of technical docouments in three volumes and dozens of
appendices, with additional volumes "under construction" that should
appear in the future.
Do you want me to provide the link as an answer so you can download
the documents directly? Or did you want me to download them myself
and pass them along to you (this is possible, but not as simple or
fast as a direct download yourself). I just need to know how you wold
like to proceed, and I'm happy to oblige.

Hello again,
Given the positive nature of your comment and arimathea-ga's very
helpful (and much appreciated) acknowledgement that INS1500 is in fact
the same thing as INS Net-1500, I will post the link to the full
technical documentation tomorrow. This will give you time to sort
through the information I've provided thus far to confirm that it is,
indeed, the information you were seeking.
