• Two RJ-11 FXS (Foreign Exchange Station) ports—The ATA 191 supports two independent RJ-11

or fax sessions, and both ports can be used simultaneously.

Ethernet-capable device, such as a computer, to the network. You connect to the network switch or a
computer running Cisco Unified Communications Manager using this port.
The ATA network port performs autonegotiation for duplex and speed. It supports speeds of 10/100 Mbps
