Proposer Sasha Townsend
Lead Analyst SEC Change
Date raised 18/08/2020
Implementation date ad-hoc Release (targeted January 2021)
Latest update The Change Board voted to approve this Modification on 20 January 2021. This Modification was implemented on 21 January 2021 as an Ad-Hoc release.

What is the issue?

There are three issues present.

The first issue relates to Communication Hub (CH) stock compliant to CHTS v1.0 and GBCS v1.0 and GBCS v1.1 being held in volume and unlikely to be installed before the IVP end date 31 January 2021.

The second issue relates to the requirement to upgrade or replace installed CHTS v1.1/ GBCS v2.0 Communications Hubs to CHTS v1.1/ GBCS v2.1 Communications Hubs by 28 February 2021, the GBCS v2.0 Applicability Period End Date.

The third issue focuses on the need to upgrade/ replace installed CHTS v1.1/ GBCS v2.1 Communications Hubs (to CHTS v1.3/ GBCS v3.2 Communications Hubs) by 31 May 2021, the CHTS v1.1 Maintenance Validity Period End Date.

What is the solution?

The DCC propose to amend the IVP and MVP dates by 12 months each, to mitigate risks presented by the current and imminent IVP and MVP dates.
