Abstract: In accordance with the method and system of the present invention, a first link protocol utilizing a set mode command is sent from one or more transmit terminals to establish a link with one or more receive terminals. The set mode command comprises a frame format including an identifying byte field in accordance with International Telecommunication Union's Q.921 Annex E protocol specification. The one or more transmit terminals wait a predetermined T200 time interval to receive a response from the one or more receive terminals to determine if the link is established. If a response is not received from the one or more receive terminals, the one or more transmit terminals resends the set mode command a predetermined N200 times. If the link is still not established within the predetermined N200 times, a second link protocol utilizing a set asynchronous balanced mode extended command having a different identifying byte field in accordance with International Telecommunication Union's Q.

Abstract: A cover is used to replace worn tread of a lawnmower tire without requiring replacement of the entire wheel and tire unit.
