Elastomeric fluoropolyether lubricant topcoats are formed on a protective overcoat of a magnetic recording medium. Cluster attributes identifying alternate bearer possibilities are exchanged between media gateways as part of capabilities negotiation which occurs during call setup conducted by an external call control element over a core network. The elongated member may include a valve near the proximal end and distal to the second retention structure. The treated fibers can be readily dispersed and uniformly distributed throughout a mixture without re-clustering or reclumping once the mechanical mixing action stops. Further, a reset controller resets the first node and the second node of the electric charge pumping means as the level of the negative voltage when the first and second pumping clock signals are inactivated. The bandwidth policy decisions are generated based on consideration of subscriber andor application service provider characteristics.
