Abstract
The extended messaging scheme adds additional packet formats to the prior art 6-byte Lucent Access Interface Unit (AIU) Message Format of Table 1. The extended messaging scheme supports multi-packet messaging over telecommunication system configurations not supported by the prior art AIU Message Format. In one implementation, the extended messaging scheme includes (1) a “first-of-many” packet format for the initial data packets of messages requiring more than one 6-byte data packet, (2) a “continuation” packet format for the one or more subsequent data packets corresponding to such multi-packet messages, and (3) a “first-and-only” packet format for messages requiring only a single data packet. The extended messaging scheme enables telecommunication systems to be configured with one or more (possibly non-co-located) client terminals in addition to a main remote terminal to provide telecommunication services to a large number of widely distributed customers.
