Overview
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 exciting IP telephony applications by connecting their analog devices to Cisco ATAs.
  • Configuration as per Cisco endpoints devices
  • Autoprovisioning with Trivial File Transfer Protocol (TFTP) for servers
  • Automatic assignment of IP address, network routing IP, and subnet mask using Dynamic Host Configuration Protocol (DHCP)
  • Touch-tone telephone keypad configuration with voice prompt
  • Administration password to protect configuration and access
  • Remote upgrades through network
  • 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
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.
