ABSTRACT:
Virtual dedicated access of telecommunication subscribers (12, 14 and 16) to an inter-exchange carrier (IXC) (20) is provided by way of an intelligent local End Office switch (180) that routes calls either to the IXC or to a local End Office switch (18). The intelligent local End Office switch (180) advantageously serves to perform inter-exchange processing of calls, as required, for calls that originate with, or terminate at, a customer rather than automatically route calls to the IXC for such inter-exchange processing, as was previously required.
