Cisco ATA 186 Analog Telephone Adaptor

Cisco ATA 186
Product Overview

The Cisco ATA186 Analog Telephone Adaptor is a handset-to-Ethernet adaptor that interfaces regular analog phones with IP-based telephony networks. The Cisco ATA 186 is installed at the subscriber`s premises and supports two voice ports, each with its own independent phone number. This adaptor takes advantage of broadband pipes being deployed through digital subscriber line (xDSL), fixed wireless, cable modems, and other Ethernet connections.

The Cisco ATA 186 is the ideal solution for service providers deploying IP telephony services in the residential market while taking advantage of the installed base of handsets. By deploying IP-based telephones as a second-line, service providers can now offer additional revenue-generating services for emerging telephony applications in their residential services portfolio. Service providers can also realize a rapid return on investment (ROI) by utilizing their existing networks and move to converged network architectures. Thus, saving capital costs along with operational and administrative costs.
