Abstract:
A proxy computer of a network can receive incoming telephony messages from one or more computers outside of the network and proxy them to computers within the network. Similarly, the proxy computer can receive outgoing telephony messages from within the network and proxy them to computers outside of the network. To set up inbound calls, a proxy program on the proxy computer looks for the presence of an alias in the call signaling messages, references a data structure to determine which computer on the network is associated with the alias, and proxies the call signaling and control messages between the callee computer and the calling computer based on the association, thereby creating a logical connection between the calling computer and the callee computer.

Abstract:
A method and circuit for detecting boron at an interface between a p-type polysilicon gate and silicon dioxide gate dielectric is provided. A V.sub.t fluence test using about -6.67 mA/cm.sup.2 is used to detect boron at the interface. A p-channel metal oxide semiconductor ("PMOS") device having a source, drain, substrate, gate and silicon dioxide layer are connected to ground and a current source in order to detect the boron. An about -6.67 mA/cm.sup.2 current is applied to the PMOS gate while the source, substrate and drain are grounded. Various changes in threshold voltages are observed over different stress times. The boron concentration at the polysilicon/gate dielectric interface has been detected by the shift in threshold voltage. The concentration of boron at the interface has been found to degrade oxide quality as evidenced by charge-to-breakdown ("Q.sub.BD ") test of the oxide.
