  • Patent number: 6363074
    Abstract: An inter-machine trunk (IMT) is provisioned between two witches through an ATM network. The IMT includes a number of virtual connections (VCs) and cell slots within each VC for carrying telephone calls. The IMT is established by multiple repetitions of an inter-switch signaling process, each resulting in the creation of one VC. The number of VCs and cell slots for the IMT is selected based on provisioning information from a network operator. The IMT may be either a pre-established IMT (“PIMT”) or an on-demand IMT (“VIMT”). A PIMT is a quasi-permanent connection set up and torn down by an operator to provide some guaranteed data-carrying capacity on the IMT. A VIMT is created automatically upon receipt of a call when no connections are available on the IMT. An IMT can use both a PIMT and a VIMT. When a call request is received at a switch, a call processor determines whether the IMT is to carry the call.

  • Patent number: 4893316
    Abstract: A digital radio receiver is described. The digital receiver of the present invention contemplates a digital radio receiver which operates on a received analog signal which has been converted to a digital form after preselection at the output of the antenna. The digital receiver of the present invention comprises a preselector, a high-speed analog-to-digital (A/D) converter, a digitally implemented intermediate-frequency (IF) selectivity section having an output signal at substantially baseband frequencies, and digital signal processor (DSP) circuit performing demodulation and audio filtering. The radio architecture of the present invention is programmably adaptable to virtually every known modulation scheme and is particularly suitable for implementation on integrated circuits.
