Product Features
Technical Overview
The Cisco ATA191-K9 operates as a dedicated VoIP gateway with Fast Ethernet connectivity supporting 10/100Base-T network standards. The device features one RJ-45 network port for connection to your local area network and two RJ-11 FXS ports for analog telephone equipment. This configuration provides direct conversion of analog voice signals to digital packets for transmission over IP networks.
The adapter does not include Power over Ethernet capability, requiring separate power provisioning through its included adapter. It also lacks USB connectivity, management ports, wireless LAN support, and SIM card expansion, maintaining a focused design for basic analog-to-VoIP conversion without unnecessary complexity.
Relevant factors for this section include PoE (RJ-45) Port, USB, Management Port, SIM Card Supported. When those points are considered together, they give buyers a clearer picture of how the product is equipped, how it fits into deployment, and what kind of day-to-day role it is meant to support.

FAQ
How many analog phones can I connect to the Cisco ATA191-K9?
The Cisco ATA191-K9 supports two separate analog telephone devices simultaneously through its dual FXS ports. Each FXS port provides a standard RJ-11 connection for traditional analog phones, fax machines, or other telephony equipment. This allows you to connect two distinct devices or create two separate extensions using a single adapter, making it efficient for small office setups or supporting multiple legacy devices during VoIP migration.
Does this adapter support Power over Ethernet (PoE)?
No, the Cisco ATA191-K9 does not include Power over Ethernet capability. The device requires separate power provisioning through its included power adapter. This means you'll need both a network connection to your switch or router and a standard electrical outlet to power the device. The absence of PoE simplifies the design for basic analog-to-VoIP conversion while maintaining reliable operation through traditional power sources.
What network speed does the Cisco ATA191-K9 support?
The Cisco ATA191-K9 supports Fast Ethernet connectivity with 10/100Base-T network standards. This provides sufficient bandwidth for clear voice communication and basic data transmission associated with analog telephone conversion. The device automatically negotiates connection speed with your network switch or router, ensuring compatibility with most modern networking equipment while delivering reliable performance for VoIP applications.
Can I mount the Cisco ATA191-K9 on a wall?
Yes, the Cisco ATA191-K9 is designed for both wall mounting and desktop placement. The compact form factor includes mounting provisions for secure wall installation, allowing you to save desk space and position the device conveniently near network connections. The lightweight construction at 4.70 ounces makes wall mounting straightforward without requiring specialized hardware, while the desktop option provides flexibility for temporary setups or easy access.
What is the warranty coverage for this product?
Cisco provides a 1-year limited warranty for the ATA191-K9 analog telephone adapter. This warranty covers manufacturing defects and ensures product reliability for business deployment. The warranty terms are standard for Cisco networking products and provide assurance of quality construction and performance. For specific warranty details and support procedures, consult Cisco's official documentation or contact their support channels directly.
What types of devices can I connect to the FXS ports?
The FXS ports on the Cisco ATA191-K9 support standard analog telephone equipment including traditional desk phones, cordless phone bases, fax machines, modems, and alarm system dialers. These ports provide the necessary voltage and signaling to power and communicate with analog devices, converting their signals for transmission over IP networks. The adapter is compatible with most analog telephony equipment that uses standard RJ-11 connections and operates within typical telephone line specifications.
