Cisco ATA-186-I1 Analog Adapter (Refurbished)
Supported Protocols: SCCP, SIP, MGCP, H.323
Installed Protocols: SCCP
Includes Free Power Supply (ATA186-PWR-CUBE)
Product Description
The Cisco ATA 186 Analog Telephone Adaptor 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.
Features
- Two voice ports support legacy (analog) touch tone telephones
- RJ 45 connection to 10BaseT Ethernet hub or switch
- Auto-provisioning with Trivial File Transfer Protocol (TFTP) provisioning servers
- Automatic assignment of IP address, network route IP, and subnet mask via Dynamic Host Configuration Protocol (DHCP)
- Web configuration through built-in Web server
- Touch-tone telephone keypad configuration with voice prompt
- Administration password to protect configuration and access
- Remote upgrades through network
- Advanced pre-processing to optimize full-duplex voice compression
- High performance line-echo cancellation eliminates noise and echo
- Voice activity detection (VAD) and comfort noise generation (CNG) save bandwidth by delivering voice, not silence
- Dynamic network monitoring to reduce jitter artifacts such a packet loss
- Session Initiation Protocol (SIP)
- Skinny Client Control Protocol (SCCP)-Cisco CallManager technology
Voice Codecs
- G.729, G.729A, G.729AB2
- G.723.1
- G.711a-law
- G.711�-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
- FC 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.
