The Cisco® ATA 190 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 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 190:
Protects existing telephone investment: The Cisco ATA 190 supports two voice ports (RJ-11 phone ports), each with its own independent telephone number, and a single RJ-45 10/100 BASE-T Ethernet port. Each port supports either voice calls or fax sessions, and both ports can be used simultaneously. This adaptor can use existing Ethernet LAN deployments.
Is cost-effective: The Cisco ATA 190 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 enterprise networks, small-office environments, or the emerging VoIP managed voice services and local services market.
Enterprise customers can use the Cisco ATA 190 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 solutions.
Features:
Configuration as per Cisco endpoints devices
Autoprovisioning with Trivial File Tansfer Protocol
Automatic assignment of IP address, network routing IPand subnet mask using Dynamic Host Ponfiguration Protocol (DHCP)
Touch-tone telephone keypad configuration with voice prompt
Administration password to protect configuration and access
Remote upgrades through network
Voice Quality
Advanced preprocessing to optimize full-duplex voice compression
High-performance line-echo cancellation to eliminate noise and echo
Voice activity detection (VAD) and comfort noise generation (CNG) to save bandwidth by delivering voice, not silence; VAD is configurable, and the ATA 190 determines whether CNG should be turned on dynamically
Dynamic network monitoring to reduce jitter artifacts such as packet loss
Signaling Protocol
Session Initiation Protocol (SIP) on the Cisco line side
Security
Secure Real-Time Transfer Protocol (SRTP) and Transport Layer Security (TLS) over SIP
Fax Support
T38 fax support
