to ISDN switches, but my experience says that it is easier
to configure devices for the 5ess switch. 5ess switch generally
don't have spids. This removes one of the major issues of
configuration from any ISDN device.

number for both b channels instead of two, more tids (if the rboc
allows) so you can use more devices on the line, and is much easier to
set up equiptment on (IMHO).

assume you use Nynex since you're on cloud9) would rather have you on
5ESS since it's eiser for them to configure your curcit. Also make sure
to ask for 2 directory # and 2 SPIDs, so you have a phone # for both B
channels.

In Ameritech's dominion, they'll often tell you the line is on a 5ESS switch
when it's actually on a DMS. I've called 1-800-TEAM-DATA and asked them
"Are you sure Circuit #XXXX is on a 5ESS?" and later found them to be wrong-
I've yet to encounter a BRI off a 5ESS.
Now they're starting to claim that some of the switches are EWSD...

Neither one is better for all operations. The DMS-100 has several areas
in which they exceed the operation of the 5ESS switch. The previous answer
is non-sense. It is because it is. Well, I can say that about almost any thing.
If you're trying to do multi-ISDN calls, then maybe the 5E has some advantages.
But if you're doing a PRI rate adaption, maybe not.

The ESS#5 is better. Because it is. :)
I have heard reports over the past year from various
people around the Washington, D.C. area trying to
get ISDN installed.
Typically, the ones served by DMS100 switches had
more problems than those served by ESS#5 switches.
Further, the DMS has some annoying limitations
in its capabilities, such as 2 S.P.I.D.s per
B.R.I..

I always default to disbelief of anything I hear
from a Tephone Cumpny representative. Even checking
with others can confirm false information.
If I must know the switch type, I consult a friend
who has access to the BellCoRe NNACL listing (for $$$).
Otherwise, assume nothing. Caveat emptor. Carpe trunkem.
Etc.

land we call NYNEX, it has become evident that when employing the Motorola
Bitsurfr to make phone calls, in particular to numbers employing voicemail -
press 1 for x, press 2 for y on a DMS100 switch there is a sudden click and
then silence, contrarily on a 5ESS the call goes through as it should.
this is still under investigation

As a retire Bellcore employee I was involved with the first ISDN
field trial in Ameritech on the 5ESS in Oakbrook, IL. The
Oakbrook switch serves the McDonalds work HQ. There are
also 5ESS's in Naperville which serves AT&T (you wouldn't
think as a major customer of local dialtone (even ISDN type)
that an RBOC will install a switch made by the competing vendor to
serve a major facility of the other vendor would you :-)
Anyway, there are many 5ESS around the USA with ISDN BRI
lines.

If I were using both B channels as individual analog phone lines,
Would a call to on channel get transfered to the other if the first
was in use?

My local CO provides BRI's from a 5ESS - I have personally seen the switch
and am about to order my BRI.

Yes, this 2 SPID/BRI limit of the DMS-100 is a pain but so
is an RBOC's tariff that limits 2 SPIDS/BRI no matter
what switch you're on (including an AT&T 5ESS).
Ameritech is one RBOC has a 2 SPID/BRI limit in their
tariff. What other LEC's have this same limitation?

I believe so, depending on the line provisioning. You'd obviously need
circuit switched voice set to 2 and any. (Simply means both b channels
are voice capable.)
Beyond that there are a number of extended services like call waiting,
forwarding, voice messaging, etc, that are available depending on the
RBOC, but on the 5e I don't think you'd need them to accomplish this.
I believe you could also do this on a DMS100, with the equivalent options
AND call forwarding. (Not 100% sure though, haven't tried.)

It is my understanding that It is not possible to set CSV to 2! You
can only do this with CSD. To the best of my knowledge this is the
case for all switch flavors (including the 5E).
This is because it was not really even considered that people would be
able to do DOSBS, and few would want dualing analog (as this can
generally be handled more efficiently with EKTS type functionality).
As I mentioned earlier in this thread, this can be done with 2 SPIDs,
and the SPIDs can be put in a hunt group or call forwarding
arrangement..
Also, CSV and CSD are PER SPID (ie logical device) parameters, not
really specifying the capabilities of the B Channels. A setting of
CSD=2 on a SPID says that the associated device can make 2
simultaneous CSD calls. It is very possible to set one SPID to CSD=2,
the other to CSD=0 (or 1)and the associated devices would be so
restricted.. The only possible values for CSV are 1 or 0. A single
physical device could make 2 CSV calls (112K using DOSBS) if it were
assigned 2 SPIDs (I have done this with a Digi PCIMAC).
Though I have probably confused the issue a little, I hope I didn't.
But bottom line is I am 99.9999% sure that CSV=2 is not possible
currently.

This can be made a function of your CPE, ala the Pipeline 25.

I can tell you with 100% certainty that the BRI here in my office
IS connected to a 5Ess, since the switch is about <50 yards from here, and you
can if interested follow the wiring almost the entire way.

This question invokes a lot of heat, because the two major vendors, NTI and AT&T have so much
at stake.
Also, the regional Bell companies have tended to install more DMS-100 than 5ESS switching
platforms, because the DMS-100 is a fair amount cheaper measured by any bjective standard.
For anyone who has had lots of experiences with switch software routines, and complex vertical
services such as Centrex, the 5ESS is the *clear* winner.
For basic switching, the DMS-100 does just fine, so most folks will never see the difference.
But, get into a complex vertical features environment, such as a large Centrex platform, and
the knowledgable administrator of a company's telecommunications requirements will opt for 5ESS
every time, given a choice.
There is no reason to believe that NTI has suddenly gotten its act together by offering a
really robust ISDN platform. Sure, it works, but not as well as the 5ESS ISDN platform. Take
multiple terminal adapters on one BRI as a starter.
The AT&T network switching designers have "forgotten" more about switching requirements and
software routines than the folks at NTI have yet to figure out.
It's one thing to have a switch provide POTs (plain old telephone service) dial tone, and it is
entirely another thing to have complex feature interactions work faithfully and reliably in
heavy-traffic environment.
If you can get BRI on a 5ESS, consider yourself very fortunate.
The telephone company folks will dodge this argument like the plague, for obvious reasons. ;-)

In Chicago, Ameritech has quite a few 5ESS switches, but TMK, delivers all
ISDN BRI's as NT1 regardless of the switch. For example, here's a snippet of
the ISDN ORDER CONFIRMATION on my personal line:

Oh yes, AT&T is GOD to software. No one else any where understands how to
write software. The ISDN provided by the 5ESS is not the end all to peoples
problems. The fact that for most calls you won;t get a full 64k Clear Channel
connection from end-point to end-point is another minor problem. This has
nothing to do on which switch you are connected. Also, I have seen dozens of
features provided by Nortel, Siemens, Fujitsu switches that are implemented
much better than the same feature on the 5E.
But from the above, I would assume you work on the 5E, so no matter what is
said, you will continue in your blind accusations of other companies.
No, I don't work for any of the above either.
