Re-accreditation requirements

Message re-accreditation will be required as follows:

• When system providers modify their software in a way that may affect or directly impact either, connectivity to CHESS Replacement or the generation of message constructs;

• To accommodate a new CHESS release, where message constructs are introduced or upgraded;

• During extended periods of absence when the software is not connected to CHESS;

• Upon specific request from the ASX; and

• In addition, re-accreditation may also be required to align to ISO 20022 version standardisation, the details of which are currently being worked through by ASX and will be communicated at a later date.

ASX will request system providers to keep ASX up to date of their current software versions, regardless of whether re-accreditation is required.
