The Intimate Communications Hub Interface (ICHIS) specification defines a common interface between Intimate Communications Hubs (ICH) and Smart Meters which will be deployed for the GB Smart Metering Implementation Programme.
The ICHIS defines the mandatory features required to ensure that an ICH can be used with any ICHIS compliant Host, as well as defining features reserved for future use or for specific implementations.
DCC will review the ICHIS as a minimum on an annual basis to ensure it remains fit for purpose and use. In Quarter 4 2018 the ICHIS was updated with:
- Temporary adjustments to noise limits for Wider Area Network (WAN) frequencies (423MHz and 900MHz); and
- Temporary adjustments to noise limits for 2.4GHz and 868MHz Home Area Network (HAN) frequency bands
It is anticipated the next review will take place in Quarter 1 2019.
Outside of the annual review, if you identify any changes or updates that are required, please email firstname.lastname@example.org detailing the proposed change and accompanying rationale for the change.
