ARRIS is the undisputed leader in supplying global cable telephony equipment, with over 8 million lines deployed worldwide. The first trials of the ARRIS Cornerstone® Voice system began in late 1995 with commercial deployments during 1996. Since early 1999, ARRIS has blended its CBR expertise along with IP research and product development to become the world’s leading provider of VoIP with PacketCable Quality of Service.

ARRIS products reflect five 9’s (99.999%) carrier-grade reliability and offer service that meets or exceeds that available from incumbent local exchange carriers. ARRIS carrier-grade standards are exemplified in the DOCSIS® 3.0, Euro-DOCSIS 2.0 and PacketCable™ 1.0 qualified ARRIS C4® Cable Modem Termination System (CMTS) which provides operators the ability to provide both voice and tiered data services over converged IP networks. Today, cable telephony is the fastest growing revenue segment for U.S. MSOs. When combined with cable modem high-speed data service and digital video, it presents a compelling triple-play offering to compete with telcos.

ARRIS pioneered cable telephony in the 1990s, and today cable systems rely on the ARRIS C4 and C3™ CMTS solutions and Touchstone® Embedded Multimedia Terminal Adapters (E-MTAs) to deliver primary line carrier grade voice service for residential and business applications. Touchstone E-MTAs provide 1-, 2-, 4-, 8- and 12-voice line models, plus a high-speed data connection, for both residential and small-to-medium businesses. Additionally, Touchstone wireless residential gateways – WTM552 -- have two analog voice lines, a four port router and a wireless access point. ARRIS leadership in the delivery of reliable voice solutions is further demonstrated with the troubleshooting and diagnostic tools Touchstone Call Quality Metrics and Loop Diagnostic features.
