Cisco ATA 186 Overview
This chapter provides an overview of the Cisco ATA 186 Analog Telephone
Adaptor and describes the system features.
About the Cisco ATA 186
The Cisco ATA 186:
•Is an Internet telephony appliance that converts any regular analog telephone
into an Internet telephone.
•Converts voice into IP data packets that are sent over a network.
•Is installed at the subscriber’s premises.
•Supports two voice ports with their own telephone numbers.
•Has one 10BaseT RJ-45 port and two RJ-11 FXS standard analog telephone
ports.
•Supports both low-complexity voice codecs, such as G.711 ,G.711A-law, and
high-complexity/CELP codecs, such as G.723.1 and G.729A.
•Can be configured to use either the H.323 or the SIP call signaling protocol.
•Operates with Cisco Voice Packet Gateways.
•Operates with H.323- or SIP-compliant Voice Packet Gateways.

•Dual RJ-11 Ports
– Supports two independent RJ-11 telephone ports that can connect to any
standard analog telephone device. Each port supports either voice calls
or FAX sessions, so that the user can talk on one port while sending a
FAX on the other.
– There are two RJ-11 FXS port terminating impedance options, 600 Ohms
resistive or 270 Ohms + 750 Ohms // 150 nF complex impedance. The
impedance of the Cisco ATA 186 depends on the option ordered and must
match the particular application. If you are not sure of the applicable
configuration, check the country or regional telephone impedance
requirements.
•Indicators
– Function Button
The Cisco ATA 186 function button is located in the top panel of the
device. The function button lights when you pick up the handset of a
telephone attached to the Cisco ATA 186. When the function button
blinks, the device is in configuration search or upgrade mode. You also
use the function button to access the interactive voice response (IVR)
configuration menu. To configure the Cisco ATA 186 by using the IVR
mode, see Chapter 3, “Configuring the Cisco ATA 186.”
– Activity LED
The green Activity LED located on the back panel flashes to indicate
network activity.
•5 Volt power adapter connector (adapter included)
•10Base-T Ethernet port
Additional Feature
Supports polarity reversal before and after caller-ID signal.
