Protocol and interfaces
C.1.1.1
Introduction
The following sections describe the protocol and interface between
the SAILOR 900 VSAT ACU and an iDirect OpenAMIP VSAT modem.
OpenAMIP operation is normally used by service providers offering
global VSAT service as the protocol supports roaming between
satellites (Automatic Beam Switching).
OpenAMIP, an ASCII message based protocol invented and
Trademarked by iDirect is a specification for the interchange of
information between an antenna controller (ACU) and a VSAT
modem (VMU). This protocol allows the VSAT modem to command
the ACU to search and lock to a particular satellite as well as
allowing exchange of information necessary to permit the VSAT
modem to initiate and maintain communication via the antenna and
the satellite. In general, OpenAMIP is not intended for any purpose
except to permit a modem and the ACU to perform synchronized
automatic beam switching.
Thrane & Thrane A/S received OpenAMIP certification for SAILOR
900 VSAT from VT iDirect Inc on 22 September 2011.
