Methods and systems for reconfigurable soft-output bit demapping, reconfigurable for different modes of operation and for different modulation schemes are provided. The main case has first and second sidewalls and a peripheral wall extending between the sidewalls which help jointly define an internal chamber therewithin for housing the coilable tape blade. The vanes are generally formed of a graphite fiber and an aramid fiber braided preform that is laminated with an epoxy matrix resin or other high temperature matrix resin. For lowering the boom, the above steps basically have to be carried out in reversed order. According to the aforesaid structure, a wire is winded and stored in the large and small wire storage wheels, respectively, and are distinguished as at least two A and B wires and at least two C and D wires being stored in the large and small wire storage grooves, thereby selectively and independently releasing at least two wires with predetermined lengths. More particularly, a novel network arrangement and method for avoiding \u201cghost calls\u201d in IP based communications networks for achieving higher session completion rates is provided.
