• Analog telephony voice devices
• The ATA supports analog telephony voice devices, such as overhead paging adapters and answering
machines, that emulate a regular phone.
• Overhead paging systems
• Overhead paging systems provide alarms and public-address announcements in buildings.
• Fax machines
• Use a fax machine directly with an ATA. Don’t connect an extension to a fax machine, and don’t
use the fax machine with a splitter.
• To reduce fax failures, use overseas mode, if available; if not, set the fax machine transmission
speed to low.
• Data devices, such as facsimile machines and modems, may not function optimally. For the best
fax and modem performance, continue to use a dedicated PSTN line.
Cisco ATA 191 and ATA 192 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 192 includes an extra LAN Ethernet port—An RJ-45 10/100BASE-T data port to connect to
a device on your network, such as a computer, using an Ethernet cable.
The ATA network port performs autonegotiation for duplex and speed. It supports speeds of 10/100 Mbps
and full-duplex.
