Implementation date Not yet determined
Latest update This modification will be discussed at the SEC Working Group on 7 October 2020 to assess Alternative Solutions.

What is the issue?

When a User sends Service Request 12.1 ‘Request WAN Matrix’ to receive Smart Metering Wide Area Network (SM WAN) Coverage, in most cases they will receive an Availability Date and WAN Variant. However, in an exception case, the Communications Service Provider (CSP) for the South and Central regions may respond to a SM WAN Coverage request (CSPM-S1 or CSPM-S2) with an Availability Date for coverage but without being able to confirm the WAN Variant that will need to be used. This results in “ “ (Space) being returned as WAN variant, which has been identified by a customer as potentially confusing. Therefore, a change in the wording has been requested.

What is the solution?

The proposed solution is to change the wording from “ “ (Space) to "Unknown". This provides a more meaningful response and removes potential confusion.

What SEC documents are affected?

SEC Appendix I 'Communications Hub Installation and Maintenance Support Materials'
