CLI and ADSL

(x-posted to uk.telecom)

Hi guys,
I have BT's Caller Display service, but have problems with my ADSL
connection.

Whenever I power up my PC and the ADSL modem synchs with the local exchange,
I lose the use of Caller Display/CLI. No information at all is displayed.

What can I do to make it work when my PC is on (nearly all the time)? BT are
no help (as usual).

Thanks in advance,

Simon

This is odd. Caller display uses an in-band signal before the fist ring, and
AFAIC, it's below the threshold of the splitter so this shouldn't be
mangling the signal.

You could try it without the splitter in the first instance, assuming you
have one inline.

if you haven't got a splitter and are relying on the phone to filter out the
high frequency stuff, that would almost certainly mangle caller display.

Regards
Andrew

This is where I am confused - I have a splitter and have no interference on
the phone line when the PC is online......

FWIW, this is pretty much what I was posting about yesterday ('BT Caller
Display + C&W phone + ADSL issue').

AIUI, BT have to do something to the ADSL filters at their end to make
this work. (this is according to Cable & Wireless, the makers of my
phone - they had a bunch of people about a year ago with the same
problem).

I think the next step is to get pushy with BT.... <sigh>

OK - so you hear no interference - perhaps your phone does. Change
the splitter for another type.

I have a number of caller display units, Easicom 200s, BT CD-50s, a
Betacom Preview 2, Telcom 630, some Telcom phone with display built in,
and have used both cheap (1.25 from ebuyer) and more expensive filters,
with each filter supporting upwards of 3 phones on long extensions etc,
etc, but caller display works through all of them, with one exception
(where a call sign switch is in place, it seemed to screen out caller
display on a very old CD-50). I think C+W are barking up the wrong
tree, but not having one of their phones, may be wrong.

As for BT, I don't know of anything they would change, except perhaps
some sort of reset of the card handling caller ID (when my first ADSL
was enabled at the exchange, there was some glitch and incoming calls
failed with a half ring and then a msg saying "there is a fault". I
was getting dial tone and knew nowt about the problem initially...
took over a week before they reset the caller display handling and
my incoming calls resumed) Peter M

I thought CLI/CD was incompatable with the ADSL service, and that if you had
CLI/CD, BT wouldn't ADSL enable the line for this very reason. In order for
BT to ADSL enable the line, they had to remove CLI/CD first.

try a Fujistsu filter. I had problems with "cheap" filters; when an old
analogue cordless phone was connected, I'd lose ADSL when the 'phone rang.
Changing the filter solved the problem.

I have two lines at home, both had CLI/CD, both were ADSL enabled and
never had a problem with either service.

We had same problem here too since getting ADSL, so went and bought new CLI
phone (BT Decor 310), plugged it in and now both old and new phones work,
take decor away, no CLI on old phone (Bt relate 350), no idea why, other
problems, digibox ( & solwise filter) wont dial out, and can't use PC's
modem either (with or without filter), oh and if router on, BT decor phone
won't recognise that answer phone message left (should check 1571 and should
illuminate small red LED), nevertheless can live with these small problems

Probably not much help but can you borrow another phone or get one under
argos 16 day money back to check if phone or not.
