Hi,

I took the risk of buying a Siemens SX353 ISDN phone from Germany in the 
hope it would work on ISDN2e, but it seems not - and there was me 
thinking the 'e' in ISDN2e was for a European standard!? Ages ago I 
bought a Euracom P4 ISDN phone and that *did* work!

Are the UK/German ISDN standards totally incompatible. I have spoken to 
Siemens and they think it won't work, but you are all very clever round 
here so I thought I'd ask before I go to plan B!

Thanks

The most likely reason for it not working is BT's Loose Interpretation of 
English and Standards (or LIES for short).

ISDN is supposed to be integrated, but BT doesn't integrate the services and 
charges for them a la carte (e.g. CLIPS, COLP etc.).

On BT [business] Highway and possibly other ISDN products there is no S-bus 
power (also non standard (BT argued it was optional)) so unpowered phones 
etc. won't work.  This meant my Swedish Ericsion ISDN phone would not work 
without a power adapter, which Siemens very kindly provided FoC.  In fact 
the power went into one port on the Highway box and came out of the other, 
so one adapter powered all my ISDN devices.

Other telco's vary.  Some provide all the facilities, but very little 
power - or non if on fibre, others just resell BT.

Is the line Point-to-Point or Point-to-Multipoint? ICBW, but I think this 
has a bearing on what type of device you can connect to the line [ie 
terminals or PBXes].

Hmm - how could I tell?

The ISDN currently goes into a Siemens Hipath but since the rental 
company want £4.5K for the next 5 years and the site only has 2 lines 
and 4 extensions I told them to come collect it as it's seriously 
over-specced.

If the 2e not in the right 'mode' can it be changed at the exchange or 
via a BT bod hitting a button on a screen?

Thanks for the other feedback.

If you currently have a block DDIs, it's set to point-to-point

The SP should be able to tell you.

It certainly requires a change order to be raised. Not sure of the 
standard lead time.

Looks like things have changed in the 10 years since I was involved.
If you knew the right number to call, you could get parameters changed
almost instantly,  PP/PMP, CLIP, MSM significant digits, etc etc
DASS2 circuits would park themselves if you as much as looked
at them IIRC, you needed a means of getting them reset PDQ

There used to be an 0800 number, but last time I 
called, it re-directed me to a web-site.
