1. A method, comprising:
- obtaining information for transmission of a data packet;
transmitting the data packet over at least one time slot from a transmission site;
calculating a value from an initial value and the information, the initial value being a function of a number of time slots of the data packet transmission;
transmitting the calculated value and the information from the transmission site;
receiving the calculated value and the information at a receiving site;
recalculating the calculated value from the received information; and
determining the number of time slots of the data packet transmission from the calculated and recalculated values.

Abstract
Systems and techniques for communications wherein a data packet is transmitted over at least one time slot from a transmission site, a value is computed from an initial value and information, the initial value being a function of the number of time slots of the data packet transmission, the value and the information is transmitted from the transmission site, the transmitted value and the information is received at a receiving site, the value from the received information is recalculated, and the number of time slots of the data packet transmission is determined from the calculated and recalculated values.
