The GBST ebms interface provides the same capability as the GBST SuperStream Gateway but is deployed and used internally within a superannuation fund (ie within the fund’s firewall) for Fund-to-Gateway messaging. This option provides the fund with EBMS 3.0 / AS4 capability for creating and processing EBMS messages, and sending and receiving EBMS messages between the fund and the fund’s gateway.

SuperStream specific rules for ebMS 3.0 / AS4 are enforced and routing of XBRL documents to product specific message queues is also available.

iqMH is the envelope for messages. iqMH provides
a messaging service for iqXBRL payloads, using the ebMS V3/AS4 Profile
standards. iqMH also acts as a compliant gateway to send and receive
ebMS packaged SBR/XBRL payloads for the industry. It packs and unpacks
ebMS3/AS4 messages, manages multiple messages, handles authentication
and transport on a 24/7 basis without relying on record keeping systems
being available 24/7
