Latest update The Change Board voted to approve this modification under Self-Governance on Wednesday 24 March 2021.

What is the issue?

GB Companion Specification (GBCS) Table 28c ‘WAN Alert and Power Event Log settings to be configured prior to installation of Devices’ is now recognised as a duplicate of normative information already existing in GBCS Table 16.2 ‘Event and Alert Codes’. This creates an inefficient use of the GBCS and could also lead to maintenance issues in the future with the same information appearing in two separate places. Additionally, GBCS Table 16.2 ‘Event and Alert Codes’ provides the full context for Event and Alert Codes, whereas Table 28c only provides a subset of this information.

GBCS Table 28a ‘Data items and values to be configured prior to installation of Devices’ contains inconsistencies with other GBCS Table with its use of “NA” in the notes column. All other tables in the GBCS contain blank cells rather than “NA”.

What is the solution?

The Proposed Solution is to remove Table 28c from the GBCS. No information will be lost as all of the information contained in Table 28c can already be found in Table 16.2. All instances of “NA” in Table 28a will also be deleted in place of blank cells to align it with the other GBCS Tables.
