[57] ABSTRACT
A communication network having a master and a plurality of remotes, these remotes supporting a plurality of co-services, in which access to inbound frequencies among the remotes is shared. When a need by a remote for an extraordinary amount of bandwidth is detected, a reserved spillover frequency from a set of frequencies is reserved for that remote. This bandwidth is reallocated when the need for extraordinary bandwidth for that remote has ended.
