Major errors in GB number plan 1.1.18, 2.1.18 and 3.1.18.

Originally posted:  2012-Sep-18.

About a year ago, I informed Cisco that various pieces of  documentation detailing the GB number plan were inaccurate, incomplete,  and out of date.

The majority of the published data seemed to be from some time  back between 2003 and 2006, but with a substantial number of additional errors and inaccuracies and certainly not up to date.

It has taken many months to get the documentation amended with the correct information, but  those changes do not appear to have made it back into the software.

I have recently seen a copy of the cisco GB number plan version 18 'dp-ffr.1-1-18.GB.exe', 'dp-ffr.1-1-18.GB.cop.sgn', 'dp-ffr.2-1-18.GB.cop.sgn' and 'dp-ffr.3-1-18.GB.cop.sgn', released only a few weeks ago, and that still has the same and many other errors included.

The faulty GB number plan file is as detailed at:

Visit the above pages, mouseover the details there, then look for the 'flat pattern file' link in the popup box, specifically:

http://www.cisco.com/web/software/282074292/51298/GBNP.txt

This file contains a large number of errors.

I enclose the original and a corrected version of the 'flat pattern file'. The corrected version has dozens of fixes detailed within.

Item 2

# 0+2[03489]+[2-9]XXXXXXX

P: 0                             NATIONAL-ACCESS

P: 2[03489]                      AREA-CODE

P: [2-9]XXXXXXX                  SUBSCRIBER

Although the 020, 023, 024, 028 and 029 area codes are valid, none of them use subscriber numbers in the whole of the [2-9]XXXXXXX range. Each area code uses only a very small part of the available range.

Each 02X area code has one hundred million possible numbers.

Allocations for London are announced in blocks of 10 million numbers e.g. (020) 3, released in blocks of one millon numbers e.g. (020) 33, and allocated 10 000 at a time to individual operators e.g. (020) 3344.

Elsewhere, numbers in other 02X area codes are anounced and released in blocks of one million e.g. (023) 82, (024) 75, (029) 22 etc and allocated in blocks of 10 000 at a time, e.g. (023) 8255, (024) 7588, (029) 2244.

In the various area codes, only (020) 3, (020) 7, (020) 8, (023) 8, (023) 9, (024) 7 and (029) 2 are designated, along with most of the range available in (028) area code (except for (028) 5 it seems).

This suggests that 0+2[03489]+[2-9]XXXXXXX is far too wide a pattern to use.

The 017683, 017684 and 017687 area codes have been identified as "special" in the above rule. These are five digit area codes with five digit local numbers, i.e. 5+5 format. These area codes share their first four digits of the area code with the separate 01768 area code which uses both 4+6 and 4+5 numbering. These are "mixed" areas.

There's another nine area codes like this:

All of the above are 5+5 format numbers. All of these five digit area codes also share their first four digits with a separate four digit area code. These are "mixed" areas.

The 016977 area code also contains some four digit numbers:

# 0+16977+[23]XXX

P: 0                             NATIONAL-ACCESS

P: 3[0347]                       AREA-CODE

P: [2-9]XXXXXXX                  SUBSCRIBER

The above rule misses 0300, 0301, 0330, 0331, 0370, 0371 and others.

Additionally, these numbers are 03XX + 7 digits, not 03X + 8 digits:

# 0+3[0347]X+XXXXXXX

P: 0                             NATIONAL-ACCESS

P: 3[0347]X                      AREA-CODE

P: XXXXXXX                       SUBSCRIBER 

These are non-geographic numbers that are charged the same as geographic rates and included in "inclusive" minutes.

There's another rule, further down the page that appears to be a duplicate for the 03XX ranges.

# 0+3XXXXXXXXX

P: 0                             NATIONAL-ACCESS

P: 3XXXXXXXXX                    03-NUMBER

It should probably be amended to this:

Nowadays there is a problem with the naming of the above tags. Numbers in the 084X ranges are no longer charged at a "local rate".

Numbers in the 0871 to 0873 ranges are regulated as premium rate services (as are 070 and 09XX numbers).

In the long term, it might be helpful to find new names for the various 084X and 087X number ranges.

There's a special NHS helpline on 0845 4647. This allocation is within the 0845 464 range which is allocated as 0+7 format, i.e. 0845 464X. No such short number allocations exist in the 0843 or 0844 area codes.

Nowadays there is a problem with the naming of this tag. Numbers in this range are no longer charged at a "local rate".

Correction to Item 12.

Corrected my typo in the  1768[347]+[2-9]xxxx  rule, in the post above and in the uploaded "corrected" files.

Changed from

1768[34]

to

1768[347]
