Systems and methods for routing communications to a platform service are provided. The VDAC card includes an array of digital signal processors which may be programmed to perform desired protocol conversions between circuit-based protocols, such as T1, E1 or J1, and packet-based protocols, such as IP. The presence of the cavity minimises the overall weight of the steering wheel. The stopper is arranged to cooperate with the spout to prevent the nozzle from falling about from the nozzle boot arrangement by rotation of the nozzle about said supporting means. The \u201chard\u201d axis is that plated perpendicular to the applied magnetic filed and saturates later, at a higher current level.
