ABSTRACT:
A method, apparatus and article of manufacture are described. In particular two network interface devices that are connected over apath that includes a digital trunk using robbed-bit signaling use a technique to identify the presence of robbed-bit signaling. The network interface devices synchronize to bytes that are subject to robbed-bit signaling. The network interface devices must synchronize to the robbed-bit signaling to avoid transmitting information or receiving information in these signaling positions. The network interface devices then take advantage of the least significant bit positions of frames that are not used for robbed-bit signaling. This results in an increase in data carrying capacity from 56 kps to 62.7 kps.
