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I informed Cisco that various pieces of  documentation detailing the GB number plan were inaccurate, incomplete,  and out of date.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

http://www.cisco.com/cisco/software/release.html?mdfid=278719042&softwareid=282074292&release=3.1.18-GB-NZ&os=Linux

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.

This file contains a large number of errors.

Item 13

# 0+1697+7[23]XXX

P: 0                             NATIONAL-ACCESS

P: 1697                          AREA-CODE

P: 7[23]XXX                      SUBSCRIBER

U: Y

Ofcom's data incorrectly marked 0169772 and 0169773 as 4+4 for many years, i.e. 01697 72XX and 01697 73XX. Later these allocations were incorrectly marked as 4+5 for a while, i.e. 01697 72XXX and 01697 73XXX. Eventually in 2010 the data was corrected. These numbers are actually 5+4 format, i.e. 016977 2XXX and 016977 3XXX.

# 0+16977+[23]XXX

Correction to Item 13.

Corrected my typo in the  16977+[23]xxx  rule, in the post above and in the uploaded "corrected" files.

Changed from

Numbers beginning 01298 28 are also 4+5 format with only 9 digits. Amend the 2[2-7] pattern to 2[2-8] here:

# 0+1298+2[2-8]XXX

Item 15

01524 and 01827 were listed after 01364 and before 01384. This is not in numerical order.

As an obvious cut and paste error, they've been moved to the correct place in the new file.

This rule can be deleted:

# 0+1557+50XXX

P: 0                             NATIONAL-ACCESS

P: 1557                          AREA-CODE

P: 50XXX                         SUBSCRIBER

U: Y

According to Ofcom, this allocation changed from 4+5 to 4+6 before 2004 and can therefore be deleted from the file.

Add an addditional rule:

# 0+1768+88[234678]XX

P: 0                             NATIONAL-ACCESS

P: 1768                          AREA-CODE

P: 88[234678]XX                  SUBSCRIBER

U: Y

The 01768 area code is marked as 'Mixed 4+5/4+6' in Ofcom data. Only numbers beginning 882, 883, 884, 886, 887, 888 are 4+5 format.

This rule can be deleted:

P: 0                             NATIONAL-ACCESS

P: 8720                          AREA-CODE

P: XXXXXX                        SUBSCRIBER

U: Y

0872 0XX XXXX numbers are already included within another rule that covers 087[1-3] XXX XXXX numbers.

Additionally, these are premium rate (small 'p') numbers.

Ian, thanks for posting this.  Have you opened a TAC case over the issue?  I would suggest that if you have not already. I'd also lean on the account manager team to insure these issues get addressed.

I have no way to raise a TAC case.

We'll just have to see whether whoever compiles these files monitors the forums.

Item 20

There's other improvements that can be made in the premium rate services ranges beginning 09, but this would need at least one additional tag.

# 0+9[018]XXXXXXXX

P: 0                             NATIONAL-ACCESS

P: 9[018]XXXXXXXX                PREMIUM-RATE-NUMBER

T: N

This should be changed to something like this (this change is not mentioned in the .txt file linked at the top of page):

# 0+90[0-7]XXXXXXX

P: 0                             NATIONAL-ACCESS

P: 90[0-7]XXXXXXX                PREMIUM-RATE-NUMBER

T: N

# 0+90[89]XXXXXXX

P: 0                             NATIONAL-ACCESS

P: 90[89]XXXXXXX                 PREMIUM-RATE-ADULT-SERVICES

T: N

# 0+91XXXXXXXX

P: 0                             NATIONAL-ACCESS

P: 91XXXXXXXX                    PREMIUM-RATE-NUMBER

T: N

# 0+98XXXXXXXX

P: 0                             NATIONAL-ACCESS

P: 98XXXXXXXX                    PREMIUM-RATE-ADULT-SERVICES

T: N

This change is the only one NOT mentioned in the uploaded corrected file at:

Thanks Ian for posting this, I'll work on getting this information to the right group(s) so these changes can be made.

Thanks for helping out.

I'm quite happy to discuss, line by line if necessary, any of these changes when you have found the right people.

Ian, I wanted to let you know that I've reached out to the dial plan team to review your comments.  I'm waiting to hear their feedback about it.  I'll let you know if we need to talk with you about it.  Thanks again.

Noted. Most of the comments should be self-explanatory, but ask away about anything you want...

Please make sure they have the latest version of comments and edited corrected file as I did fix a couple of typos.
