Abstract
A method of telecommunication network switch port polling enables very highly channelized ports to be polled. A polling engine reads information from at least one of a plurality of poll registers, and each of the plurality of poll registers is associated with a unique identifier. Depending on the information read from the at least one poll register, the polling engine reads a channel number representing the channel to be polled from a location in channel memory. The polling engine determines the location from the unique identifier associated with the at least one poll register from which the information is read. The polling engine polls channel represented by the read channel number.
