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

Form Factor

• Fits in most environments

Physical Specifications

Power

• Power supply: Universal AC power supply 100 and 240V
• DC input voltage: 5 VDC at 2.0A maximum power consumption: 5W

Physical Dimensions

• (H x W x D) and weight 3.98 x 3.98 x 1.10 in. (101 x 101 x 28 mm)
• Unit weight: 5.40 oz (153g)

Software Specifications

Configurable tones: Configurable for two sets of frequencies and single set of on/off cadence
Dual-tone multi-frequency: (DTMF) DTMF tone detection and generation

Fax

• Fax pass-through and T.38 fax relay mode
• Enhanced fax pass-through is supported on the Cisco ATA. Fax transmission rate is up to 14 kbps in T38 mode and 34 kbps in fax pass-through mode. The rate is not configurable, and the Cisco ATA 190 autonegotiates and chooses the maximum rate.

Line-Echo Cancellation

• Echo canceller for each port
• Double-talk detection

Out-of-band DTMF

• RFC 2833
• Note: You cannot transmit RFC 2833 and in-band signaling simultaneously.

Configuration

• DHCP (RFC 2131)
• Web configuration through built-in web server
• Touch-tone phone keypad configuration with voice prompt
• Basic boot configuration (RFC 1350 TFTP Profiling) by touch-tone phone keypad or built-in web server
• Dial-plan configuration through Cisco UCM
• Cisco Discovery Protocol through Cisco UCM

Security

• Encrypted TFTP configuration files

Voice Coders-Decoders (Codecs)

• G.729A and G.729AB
• G.711 a-law
• G.711 mu-law
