Abstract
ABSTRACT The invention relates to the configuration of Network Access Devices (NAD's) and more specifically, to the detection of the type of protocol encapsulation used on an xDSL line for an ATM VC. The steps occurring in the encapsulation autodetection scheme are as follows. First, the protocol settings are configured for the channel. Then, a packet is created according to the protocol and sent. Any replies received within a timeout delay are recorded. If some replies are received in time, then the autodetection for the particular protocol setting is successful and the autodetection scheme can either abort or continue with another protocol setting, if wanted. If no replies are received in time, the autodetection scheme is started over with other protocol settings.
