In a data communication system capable of variable rate transmission, high rate packet data transmission improves utilization of the forward link and decreases the transmission delay. An engaging portion with a rear end surface is provided in the annular member. Length-adjustable tie-rods are coupled to the spindles and adjustable in order that a laser beam emitted from one toe gauge impinges on the target of the other toe gauge when the toe-in is within a prescribed range for resulting in steering and tire wear characteristics. 5 to about 7 m, and a cleaning ratio of from about 0. According to the embodiments, counting of UEs using an MBMS can be performed by using a predetermined sequence. on to a cable drum, orderly and layered, such that the moments of force experienced by the device according to the present invention is minimized thereby providing a simpler design that is cheaper to manufacture and maintain.
