​​ISPC Notification Form

Assignment or withdrawal of International Signalling Point Codes (ISPC) for Signalling System No. 7 (According to ITU-T Recommendation Q.708 (03/99))

• Notification form for assignment or withdrawal of International Signalling Point Codes (ISPC) for Signalling System No. 7 (According to ITU-T Recommendation Q.708 (03/99))

Note by the TSB

• Recommendation Q.708 states that the assignment of signalling area/network codes (SANC) is to be administered by TSB. The assignment of international signalling point codes (ISPC) will be made by each country who will then notify TSB.
• In order to keep the list up to date, Administrations are, therefore, requested to notify TSB, by using the notification form, as soon as an ISPC assignment or withdrawal is made.
• This List will be updated by numbered series of amendments published in the ITU Operational Bulletin. Furthermore, the information contained in this Annex is also available on the ITU home page http://www.itu.int/itu-t/bulletin/, and can be consulted by subscribers by remote access.
