The Cisco Analog Telephone Adaptor (ATA) products are standards-based communication devices that deliver true, next-generation voice-over-IP (VoIP) terminations to businesses and residences worldwide.
The Cisco ATA 180 series are mixed-environment adaptors that interface legacy analog telephones, fax machines, analog conference telephones and other analog devices to IP based telephony networks thereby allowing companies to protect their investments in analog phones, fax machines, and speakerphones, and migrate to IP at their own pace. These products address the needs of enterprises, small-office environments, and the emerging VoIP managed voice services and local services market by helping companies cost-effectively turn their analog devices into IP devices.
The Cisco ATA 180 series is installed at the subscriber's premises and supports two voice ports, each with its own independent telephone number. The Cisco ATA 186 supports a single 10/100BaseT Ethernet port. This adaptor can make use of existing Ethernet LANs, in addition to broadband pipes such as digital subscriber line (DSL), fixed wireless and cable modem deployments. In addition, the Cisco ATA 188 has an internal Ethernet switch which allows for a direct connection to a 10/100BASE-T Ethernet network via an RJ-45 interface, with single LAN connectivity for both the Cisco ATA 188 and a co-located PC or other Ethernet-based device.
