Cisco · HMIs & Displays
Description The Cisco ATA186-I2-A is a 2-port analog telephone adapter that allows traditional telephones to connect to IP-based networks via a single 10BaseT Ethernet port. It supports complex impedance and provides independent voice communication through two analog ports. Technical Specifications Condition New/Never Used Surplus Brand Cisco Category VoIP & Telephony Part Number ATA186-I2-A Subcatecory Analog Telephone Adapters Analog Ports 2 x RJ-11 (independent numbers supported) Ethernet Port 1 x 10BaseT LAN (RJ-45) Data Link Protocol Ethernet Impedance 270Ω + 750Ω Compatible Networks Ethernet LAN, DSL, Cable Modem, Fixed Wireless Form Factor External Dimensions (H x W x D) 6 in x 13 in x 18 in Weight 20 lbs Information About ATA186-I2-A The ATA186-I2-A is designed to enable seamless voice communication over IP networks by connecting analog phones or fax machines to Ethernet LANs or broadband internet connections. Each of the two RJ-11 analog ports operates independently and can be assigned separate telephone numbers. The device supports complex impedance (270 ohms in series with 750 ohms and 150 nF in parallel), making it suitable for international telephony standards. It operates over Ethernet (10BaseT), making it compatible with DSL, cable modem, and fixed wireless broadband infrastructure. Key Features: Analog Ports: 2 RJ-11 ports supporting independent telephone numbers for analog voice or fax communication. Impedance Support: Complex impedance (270Ω + 750Ω || 150nF) ensures compliance with diverse analog standards. Network Connectivity: 1 x 10BaseT Ethernet port for LAN or broadband connection to VoIP services. Protocol Support: Uses Ethernet as the primary data link protocol for IP voice transmission. Deployment Flexibility: Works with DSL, cable modem, or fixed wireless broadband access. Form Factor: External, compact unit for convenient placement and integration. The ATA186-I2-A provides a cost-effective and reliable solution for bridging analog devices into VoIP networks using existing broadband and Ethernet infrastructure.
