Method and apparatus for alleviating switch congestion caused by long hold times for on-line access calls. A protocol converting device is connected to the originating switch in a public network, usually an ISDN switch. We call the protocol converting device a &ldquo;smart connector&rdquo;. The smart connector is connected to the switch by a high speed LAN. The smart connector and the switch include computer program code and hardware which allow the smart connector to transparently re-direct on-line access calls away from the switch and the public network and to a service provider, usually an Internet service provider, through a dedicated data network connected to the provider's point-of-presence (POP). The smart connector provides protocol conversion functions.

Converting device for alleviating switch congestion caused by long hold times for on-line access calls

Method and apparatus for identifying on-line access calls in a network switch. The switch determines which calls are to an on-line service provider, usually an Internet service provider or ISP. The switch then determines if the service provider has enough ports available to handle the call, and if the connection to a dedicated data network has enough capacity. The call can then be handled as an on-line access call and routed accordingly. The initial determination as to whether the call is an on-line access call can be made by analyzing information received when the call is initiated such as the called party number digits or by a query initiated by an advanced intelligent network (AIN) trigger.
