RCS20 M:N Redundancy Switch Appendix A
TM056 – Rev. 2.3 A-1
Appendix A – Remote RLLP
When new features are added to Radyne ComStream, Inc. equipment, the
control parameters are appended to the end of the Non-Volatile Section of
the Remote Communications Specification, and status of the features, if
any, are added at the end of the Volatile Section. If a remote M&C queries
two pieces of Radyne ComStream, Inc. equipment with different revision
software, they could respond with two different sized packets. The remote
M&C MUST make use of the non-volatile count value to index to the start of
the Volatile Section. If the remote M&C is not aware of the newly added
features to the product, it should disregard the parameters at the end of the
Non-Volatile Section and index to the start of the Volatile Section.
Before creating any software based on the information contained in this
document, contact the Radyne ComStream, Inc. Customer Service
Department (602-437-9620) to find out if the software revision for that piece
of equipment is current and that no new features have been added since
the release of this document.
