Cisco ATA 191 Quick Start Guide

Cisco ATA 191 Hardware
The ATA 191 and ATA 192 are compact, easy to install devices.
The unit provides these connectors:
• 5V DC power connector.
• Two RJ-11 FXS (Foreign Exchange Station) ports—Your ATA has two RJ-11 ports that work with any
standard analog phone device. Each port supports either voice calls or fax sessions, and both ports can
be used simultaneously.
• One WAN network port—An RJ-45 10/100BASE-T data port to connect an Ethernet-capable device to
the network.
The ATA network port performs autonegotiation for duplex and speed. It supports speeds of 10/100 Mbps
and full-duplex.
