The purpose of the HD migration program is to increase the capacity of the DSLAM (Digital Subscriber Line Access Multiplexer) in order to service more homes with superfast broadband. The small DSLAM capacity is increased from 128 ports to 256 ports. Whereas the Large DSLAM is increased from 288 ports to 384 ports.
