Abstract: A method and system for configuring an EGM from a remote terminal thereby providing improvements in operational efficiency when configuring EGMs. For example, operational efficiencies are possible by providing direct access to configure an EGM without the technician traveling to the physical machine, which may be miles away. For local EGM's, there will be efficiencies obtained by the number of EGM's configured per hour/per technician. For extremely remote EGM's, there are additional efficiencies by the reduction of travel and lodging expenses for the technician. Additionally, remote configuration of an EGM reduces security overhead.

Abstract: A method for transmitting a packet from a transmitter to a receiver in a wireless communication system begins by building a packet by a transport format combination (TFC) selection process, and the packet is transmitted from the transmitter to the receiver. If the transmitter receives an indication that the packet was not successfully received at the receiver, the packet is retransmitted via a hybrid automatic repeat request (HARQ) procedure. If the HARQ procedure did not successfully transmit the packet, then the packet is retransmitted via a retransmission management (RM) procedure. If the RM  procedure did not successfully transmit the packet, then the packet is discarded by the transmitter.
