Latest update This modification was implemented on 27 January 2022 (ad-hoc SEC Release).

What is the issue?

An issue has been identified relating to Communications Hub stock compliant to SEC Schedule 10 ‘Communications Hub Technical Specifications’ (CHTS) v1.0 and v1.1 and SEC Schedule 8 ‘GB Companion Specification’ (GBCS) v1.1 and v2.1 being held by Parties in volume. Parties are unlikely to be able to install them before the current Installation Validity Period (IVP) dates which are 31 January 2022 and 30 April 2022 respectively.

The current Maintenance Validity Period (MVP) end date for CHTS v1.0 and v1.1 and GBCS v1.1 and v2.1 means there is a risk that there will a period where Communications Hubs will be non-compliant with a version of CHTS/GBCS with valid maintenance end dates.

Furthermore, if the current IVP end dates remain, there is a high risk that Suppliers will have stock that they can no longer install and will need to be scrapped.

What is the solution?

The Proposed Solution is to extend the IVP and MVP end dates for CHTS v1.0 by 12 months. These dates would be changed to 31 January 2023 and 28 February 2023 respectively.

For CHTS v1.1 the IVP and MVP end dates will be extended by two years to 30 April 2024 and 31 May 2024 respectively.
