The market for DLC/MSAN (Digital Loop Carrier/ Multi-Service Access Node) equipment is on the rise, as shipments to telecom carriers will jump from 24 mln ports in 2004 to 36.9 mln ports in 2009, reports In-Stat. DLCs that provided remote termination of POTS lines in the access network have evolved to become MSANs that support POTS, DSL, and FTTP access lines. In-Stat expects worldwide DLC/MSAN POTS + DSL revenues to stay relatively flat for the next five years, due to heavy price competition among the vendors. Huawei continued to be the worldwide leader in overall DLC/MSAN port shipments in 2004, with about a 36% market share, and Alcatel was second, with a 21% market share. A number of vendors support VoIP media gateway functionality to enable replacement of Class 5 PSTN switches.
