Abstract

Slot assignment of RF channels in a TDMA sys- tem is simple if only one time-slot is involved in a service call, this is typically the case with wireless POTS service. In the Hybrid Fibre Coaxial (HFC) RF environment, where services such as two-line POTS, multi-line POTS, Basic Rate ISDN and multi-rate ISDN can be integrated in a subscriber unit, time-slots assignment becomes more challeng- ing since the requested bandwidth and scheme from calls can be varying, and that is further complicated by the presence of cable ingress noise. Inadequate channel management will result in inefficient use of cable RF resource, and consequently, quality of ser- vice can be affected and call blocking probability will increase.
