A Cable AML wireless network carrying digitized television and Internet backbone data now provides several smaller California communities with the same level of service available in larger communities served by metropolitan fiber.

The system transports fourteen NTSC television off-air channels and 100Base T data. The signals are MPEG-2 encoded, multiplexed, and modulated using Cable AML’s DHM-4001 digital headend mod-ules. The QPSK-modulated video is multiplexed with the Ethernet data and transported 26 miles (42 km) to a bidirectional repeater site and then on to two communities, one 35 miles (56 km) away and the other 16 miles (25 km) away.

By adding Internet backbone capacity to a digitized video backbone transport link, Adelphia can offer much higher data rates to its DOCSIS cable customers at a low incremental capital cost and without paying monthly transport fees to the common carrier.
