The United Kingdom is changing its telephone numbers, again!
There's a quick summary below and a reference point for further details
Peter Radford
The main changes affect the fixed network telephone numbers in areas that
are running out of numbers; however the opportunity is being taken to
introduce other changes to make the numbering scheme more easily
understandable. These other changes affect mobile numbers and special rate
and premium rate services; of these, only the mobile number changes are
discussed below.
The fixed network changes affect numbers in Cardiff, Coventry, London (both
Inner and Outer London), Portsmouth, Southampton and the whole of Northern
Ireland. All these areas will have numbers that, from outside the UK, will
now begin +44 2X followed by an 8-digit local number. For example, London
numbers will now begin +44 20. Those (Inner London) numbers which were +44
171 XXX XXXX will become +44 20 7XXX XXXX, with 7XXX XXXX being the new
local number; similarly, those (Outer London) numbers which were +44 181 YYY
YYYY will become +44 20 8YYY YYYY. The different area codes for Inner and
Outer London disappear. Changes for the other areas are detailed in
www.numberchange.org. (Note that the Portsmouth and Southampton areas are
merged behind one area code, as are all the old Northern Ireland areas.)
The new local numbers take effect on 22nd April but you can use the full
numbers now, the old geographic area codes and numbers can be used until
later this summer.
The mobile number changes are part of the move to re-organise the numbering
scheme, so that +44 7 will denote what OFTEL, the UK Regulator, calls "Find
Me Anywhere numbers" (personal numbers, mobiles and pagers). Any existing
mobile or pager number that does not begin +44 7 is being changed. In a few
cases, an extra digit is inserted (so that +44 860 XXXXXX becomes +44 7860
XXXXXX). In other cases, the change is not quite as simple (for example, +44
370 XXXXXX becomes +44 7770 XXXXXX) and look up tables (see below) must be
used to determine the new numbers.
The new numbers can all be used now; the old mobile numbers will stop
working at the end of April next year.
If you need to find a new number, the www.numberchange.org web-site offers a
number conversion facility.

Dear colleagues,
ICCT 2000 is a TC6 event which is a part of the IFIP world congress.
The world congress consists of eight conferences, ICCT is the second
biggest of them. ICCT has already a tradition in China (the present event
will be number nine or so), it has been integrated into IFIP for the first
time.
The schedule of ICCT and the world congress is as follows:
Monday, 21 August 2000: Plenary sessions for whole IFIP (many greeting
addresses, panels with general topics), i.e.
not too much TC6 specific.
Tuesday, 22 Aug. ICCT conference; a huge (!) event with very many
- Thursday, 24. Aug.: papers: more than 300 papers in six parallel
sessions; acceptance rate was around 75 percent;
a somewhat smaller acceptance rate would have been
a matter of serious discussion but an accepted
manuscript delivers (at least) one paying (!)
participant - and the organisors need many
paying participants since the conference location
(the international convention center) is expensive.
By the way:
- Every participant (apart from the invited speakers) will have to pay
the registration fee of US dollar 530 (for early registration, USD 580
otherwise)!
- The organisors would appreciate it very much if some TC6 delegates
would be willing to chair a session; names of chairpersons must be fixed
by the end of May, thus we can discuss that in Paris.
I have already expressed my concern that the willingness for paying
the registration fee for the task of chairing a session (and to attend
the banquet on Monday evening) will probably be rather limited.
My proposal was that the registration fee is waived for TC6 delegates
who chair a session but the chairpersons would in that case also
not go to the banquet (forget about the banquet: there are so
many other alternatives for a good meal in Beijing which cost a tiny
fraction of the banquet's price). It appears that this registration
fee waiving might be accepted but we will have to clarify this.
- All the three days of ICCT 2000 have this huge number of six or even
seven parallel streams with one exception:
Wednesday morning (this might still be changed to Thursday morning)
is a plenary session consisting of 4 invited presentations:
One by Nokia, one by Lucent, one by a Chinese leading reasearcher
and one by Andre Danthine; 45 minutes per presentation.
The organisors will ask Augusto Casaca for chairing that session.
- TC6 delagates will depart by bus to the venue of TC6 meeting 2/2000
on Thursday afternoon.
The organisors will ask for an IFIP grant in order to facilitate the
arrangements for ICCT 2000. Indeed that is what I proposed to them.
They affirmed that they would follow the IFIP rules for such a grant.
The size of such a potential grant and for what such a grant should be
used will have to be discussed at meeting 1/2000 in Paris.
Best regards
Otto Spaniol
Dear colleagues,
last Thursday I had a meeting with Prof. Hu Dao-Yuan. We discussed the
conference ICCT 2000 which is part of the IFIP world congress
(a separate mail for that will follow) and the organisation of the
IFIP TC6 meeting immediately after ICCT 2000.
Prof Hu will not be able to attend meeting 1/2000 in Paris.
After our discussion last week I can give you the following proposal
and some more information about the meeting 2/2000.
Prof. Hu will need informations about attendance as early as possible
since the meeting location is highly booked due to its attactiveness.
It would be best if he gets your reponse until the end of June at the
latest in order to make the necessary room reservations.
The proposal is as follows:
- TC6 meeting 2/2000: Friday, 25 August + Saturday, 26 August
- Location: at the Great Wall, Mutianyu section; extremely beautiful
but less crowded than the other Great Wall locations such as
Badaling.
The venue is some 60 km in North-East direction of the centre of Beijing.
It is very convenient that the airport is also North-East of the
centre (23 km from the centre); thus participants who cannot use the bus
transportation for time reasons may take a taxi (which is rather cheap)
from/to the airport.
I got a flyer from the hotel and will bring it to meeting 1/2000 in
Paris. The hotel appears to be excellent. It has a lot of nice
facilities (large swimming hall, bowling area,...) and it is
comparatively very cheap (approx. US dollar 60 per night).
It would be possible to share rooms without problems since the
rooms are spacious. Thus you might try to find another delegate
for room sharing in order to save some cost if you want so.
- Transportation:
Thursday, 24 August in the afternoon at the end of ICCT 2000
by bus from the Beijing convention center.
Return by bus on Sunday, 27 August in the morning to the airport; many
flights (SAS, Malev, Swissair, Lufthansa, JAL,...) depart on Sunday in
the late morning; in particular cases a taxi would have to be used.
In the "standard case" you would then need three nights in the meeting
hotel; if you attend ICCT 2000 then you may select out of the hotels
in Beijing which have been recommended for IFIP with special rates.
- Meeting schedule:
Friday: full day for the meeting
Saturday morning: visit the Great Wall section at Mutianyu
(this is *** absolutely *** phantastic and not to be missed!!!!)
Saturday afternoon: continuation of the meeting.
To my opinion, this will be a perfect arrangement of the meeting.
I'll keep you informed. Please inform Prof. Hu (Email <hdy(a)tsinghua.edu.cn>)
as early as possible about your travel schedule. I can only recommend to
attend that meeting and, of course, the preceding conference ICCT 2000.
Best regards
Otto

Dear TC6 members,
As you remember a group was nominated in the last TC6 meeting to prepare
the restructuring of the Working Groups. Work went on by e-mail within
this group and although the work has not finalised yet, it is time to
open the proposals to the entire committee, in order that all of us are
able to discuss and conclude the WG restructuring in Paris.
In the proposal that follows, I think that, somehow, I interpret the
feeling of the majority of members in the group, but from the formal
point of view, please consider it only under my responsibility. The idea
is that for those of you, who wish to do so, comments, negative or
positive, can be done before the paris meeting, in order that we have
a better proposal.
Basically, I propose to keep the same Working Groups, although some of
them with a different name and scope.
In summary I propose:
WG 6.1: new name
WG 6.2: new name and scope
WG 6.3: no change
WG 6.4: new name and scope
WG 6.6: new name and scope
WG 6.7: no change
WG 6.8: new scope
WG 6.10: new scope
No change is proposed for the Task Groups.
In attach you will find two files. One contains the existing names,
aims and scope of the WGs. The other one contains in a simple form the
new names and items proposed for the WGs.
I would like ask to the WG chairmen involved in any type of change to
comment the respective proposal asap. In this case, I am referring to
Guy Leduc, Samir Tohme, Guy Pujolle, Wolfgang Zimmer, Jan Slavik and
Harmen van As.
After we reach an agreement we need to write the detailed aims and scope
for each of the WGs. I would leave this task to the respective WG
chairmen.
I wish you a nice weekend
Augusto Casaca
