TEI

[Dave Liquorice]

How do you edit tei assignment?

I don't think you can. The TEI (Terminal Equipment Identifier) is
negociated between the exchange and the terminal adapter(s) to
uniquely identify each bit of kit.

I constantly get a tei error and I have to restart to solve the
problem.

Suggests to me a fault or iffy kit somewhere (yours, NTE, line or
exchnage card). More details required about the type of ISDN you have,
how far from the exchnage you are, what kit you have, how it's
connected to the NTE, are voice calls clean and free of any line
noises etc etc.

Voice calls free and clean. BT home highway terminal adaptor connected by
USB or RJ45 to Hayes ISDN modem. Both ways same fault. Less than a mile to
exchange. 2.8GHz processor 1gig ram Windows XP, USB 2.0. Most recent BIOS
and all available updates.

So not a very noisy line then giving the digits a headache, it has to
be very noisy before ISDN gets seriously upset though.

I don't understand that statement.

What is a "BT home highway terminal adaptor"? If it's a Terminal
Adaptor why do you need to connect via another box, the the "Hayes
ISDN modem" and then presumably to your computer? A TA should produce
a signals suitable for direct connection to your PC via ethernet,
RS232 or USB.

What is a "Hayes ISDN modem" why bother going back to analogue and
thus limiting the connection speed, when you have an ISDN connection
available?

The New BT Home highway boxes have a USB connection, doesn't do
compression though you have to do it in software (Win98) 2000 doesn't do
STAC in software. I have a Zyxel which I believe is the same as the
Hayes T/A very good only problem is this will easily overrun a standard
serial port (16550 based) and needs a 16750 based one as it will DTE at
upto 430K. Can't say i've ever seen these errors and I've seen a few
with ISDN. I wonder if BT have set the HH settings properly, I've known
them to bugger them up and get all the numbers assigned to the wrong
ports for one thing. So they MAY have set something incorrectly. Trouble
I had was getting anyone on the line who actually knew what I was
talking about. Luckily this one was actually Business Highway so I just
stamped my feet for long enough (Claimed that the downtime on the FAX
number was hurting business and there could be a claim for compensation
etc. etc.) and they sent out an engineer who I could actually explain it
to and he had contact numbers for the people who could actually FIX the
configuration while he was on-site.

Be careful though, if it IS your configuration expect a bill!!!!

Good Luck.

The New BT Home highway boxes have a USB connection,

I know, but that is the Network Terminating Equipment (NTE) bolted to
the wall not a Terminal Adapter (TA).

An NTE converts (in the case of Highway) the 144kbps data stream on
the line to two analogue ports and a two digital interfaces, one USB
one standard ISDN S0 bus.

A Terminal Adapter converts the S0 bus into what ever the "terminal"
can understand, ethernet, USB, RS232, WHY.
