The Cisco ATA 186 Analog Telephone Adapter is a handset-to-Ethernet adaptor that turns traditional telephone devices into IP devices. Customers can take advantage of the many new and exciting IP telephony applications by connecting their analog devices to Cisco ATAs.
The Cisco Analog Telephone Adaptor products are standards-based communication devices that deliver true, next generation voice-over-IP (VoIP) terminations to businesses and residences worldwide.
PROTECTS LEGACY TELEPHONE INVESTMENT
The Cisco ATA 186 supports two voice ports, each with its own independent telephone number, and a single 10BaseT 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.
COST EFFECTIVE
The Cisco ATA 186 helps customers turn their analog phone devices into IP devices cost-effectively and is the preferred solution to address the needs of customers who connect to either enterprise networks, small-office environments, or the emerging VoIP managed voice services and local services market.
Enterprise customers are using the Cisco ATA 186 to connect analog phones and FAX machines to their VoIP network. Service providers are taking advantage of emerging telephony applications and the ease of deploying second-line services using the Cisco ATA 186.
Cisco ATA 186-Endpoint for an End-to-End Broadband System. The Cisco ATA 186 allows you to connect analog telephones and faxes to an IP telephony network.
SOFTWARE SPECIFICATIONS
Voice-over-IP (VoIP) Protocols
Voice Codecs*
• G.729, G.729A, G.729AB2
• G.723.1
• G.711a-law
• G.711µ-law
* In simultaneous dual-port operation, the second port is limited to G.711 when using G.729.
Provisioning and Configuration
• DHCP (RFC 2131)
• Web configuration via built-in Web server
• Touch-tone telephone keypad configuration with voice prompt
• Basic boot provisioning (RFC 1350 TFTP Profiling)
• Dial plan provisioning
• Cisco Discovery Protocol for SCCP
Security
• RC4 encryption for TFTP configuration profiles
Dual-Tone Multi-Frequency (DTMF)
• DTMF tone detection and generation
Out-of-Band DTMF
• RFC 2833 AVT tones for SIP, MGCP, SCCP
Call Progress Tones
• Configurable for two sets of frequencies and single set of on/off cadence
Line-Echo Cancellation
• Echo canceller for each port
• 8 ms echo length
• Nonlinear echo suppression (ERL greater than 28 dB for f = 300 to 3400 Hz)
• Convergence time = 250 ms
• ERLE = 10 to 20 dB
• Double-talk detection
Voice Features
• Voice activity detection (VAD)
• Comfort noise generation (CNG)
• Dynamic jitter buffer (adaptive)
Fax**
• G.711 fax pass-through
• G.711 fax mode
** Success of fax transmissions up to 14.4 kbps depends on network conditions and fax modem/fax machine tolerance to those conditions. Network must have reasonably low network jitter, network delay, and packet loss rate.
