THE SPECIFICATIONS AND INFORMATION REGARDING THE PRODUCTS IN THIS MANUAL ARE SUBJECT TO CHANGE WITHOUT NOTICE. ALL
STATEMENTS, INFORMATION, AND RECOMMENDATIONS IN THIS MANUAL ARE BELIEVED TO BE ACCURATE BUT ARE PRESENTED WITHOUT
WARRANTY OF ANY KIND, EXPRESS OR IMPLIED. USERS MUST TAKE FULL RESPONSIBILITY FOR THEIR APPLICATION OF ANY PRODUCTS.

THE SOFTWARE LICENSE AND LIMITED WARRANTY FOR THE ACCOMPANYING PRODUCT ARE SET FORTH IN THE INFORMATION PACKET THAT
SHIPPED WITH THE PRODUCT AND ARE INCORPORATED HEREIN BY THIS REFERENCE. IF YOU ARE UNABLE TO LOCATE THE SOFTWARE LICENSE
OR LIMITED WARRANTY, CONTACT YOUR CISCO REPRESENTATIVE FOR A COPY.

The following information is for FCC compliance of Class A devices: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant
to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial
environment. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed and used in accordance with the instruction manual, may cause
harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case users will be required
to correct the interference at their own expense.

The following information is for FCC compliance of Class B devices: The equipment described in this manual generates and may radiate radio-frequency energy. If it is not
installed in accordance with Cisco’s installation instructions, it may cause interference with radio and television reception. This equipment has been tested and found to
comply with the limits for a Class B digital device in accordance with the specifications in part 15 of the FCC rules. These specifications are designed to provide reasonable
protection against such interference in a residential installation. However, there is no guarantee that interference will not occur in a particular installation.

Modifying the equipment without Cisco’s written authorization may result in the equipment no longer complying with FCC requirements for Class A or Class B digital
devices. In that event, your right to use the equipment may be limited by FCC regulations, and you may be required to correct any interference to radio or television
communications at your own expense.

You can determine whether your equipment is causing interference by turning it off. If the interference stops, it was probably caused by the Cisco equipment or one of its
peripheral devices. If the equipment causes interference to radio or television reception, try to correct the interference by using one or more of the following measures:

• Turn the television or radio antenna until the interference stops.

• Move the equipment to one side or the other of the television or radio.

• Move the equipment farther away from the television or radio.

• Plug the equipment into an outlet that is on a different circuit from the television or radio. (That is, make certain the equipment and the television or radio are on circuits
controlled by different circuit breakers or fuses.)

Modifications to this product not authorized by Cisco Systems, Inc. could void the FCC approval and negate your authority to operate the product.

NOTWITHSTANDING ANY OTHER WARRANTY HEREIN, ALL DOCUMENT FILES AND SOFTWARE OF THESE SUPPLIERS ARE PROVIDED “AS IS” WITH
ALL FAULTS. CISCO AND THE ABOVE-NAMED SUPPLIERS DISCLAIM ALL WARRANTIES, EXPRESSED OR
LIMITATION, THOSE OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT OR ARISING FROM A COURSE OF
DEALING, USAGE, OR TRADE PRACTICE.

IN NO EVENT SHALL CISCO OR ITS SUPPLIERS BE LIABLE FOR ANY INDIRECT, SPECIAL, CONSEQUENTIAL, OR INCIDENTAL DAMAGES, INCLUDING,
WITHOUT LIMITATION, LOST PROFITS OR LOSS OR DAMAGE TO DATA ARISING OUT OF THE USE OR INABILITY TO USE THIS MANUAL, EVEN IF CISCO
OR ITS SUPPLIERS HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

starting point for all technical assistance. Customers and partners can obtain online documentation,
troubleshooting tips, and sample configurations from the Cisco TAC website. Cisco.com registered
users have complete access to the technical support resources on the Cisco TAC website, including TAC
tools and utilities.

Cisco.com

Cisco.com offers a suite of interactive, networked services that let you access Cisco information,
networking solutions, services, programs, and resources at any time, from anywhere in the world.

Cisco.com provides a broad range of features and services to help you with these tasks:

• Streamline business processes and improve productivity

Preface

• Register for online skill assessment, training, and certification programs

To obtain customized information and service, you can self-register on Cisco.com at this URL:

http://www.cisco.com

Technical Assistance Center

The Cisco TAC is available to all customers who need technical assistance with a Cisco product,
technology, or solution. Two levels of support are available: the Cisco TAC website and the Cisco TAC
Escalation Center. The avenue of support that you choose depends on the priority of the problem and the
conditions stated in service contracts, when applicable.

We categorize Cisco TAC inquiries according to urgency:

• Priority level 4 (P4)—You need information or assistance concerning Cisco product capabilities,

product installation, or basic product configuration.

• Priority level 3 (P3)—Your network performance is degraded. Network functionality is noticeably

impaired, but most business operations continue.

• Priority level 2 (P2)—Your production network is severely degraded, affecting significant aspects

of business operations. No workaround is available.

• Priority level 1 (P1)—Your production network is down, and a critical impact to business operations

will occur if service is not restored quickly. No workaround is available.

Cisco TAC Website

You can use the Cisco TAC website to resolve P3 and P4 issues yourself, saving both cost and time. The
site provides around-the-clock access to online tools, knowledge bases, and software. To access the
Cisco TAC website, go to this URL:

Preface

All customers, partners, and resellers who have a valid Cisco service contract have complete access to
the technical support resources on the Cisco TAC website. Some services on the Cisco TAC website
require a Cisco.com login ID and password. If you have a valid service contract but do not have a login
ID or password, go to this URL to register:

http://tools.cisco.com/RPF/register/register.do

If you are a Cisco.com registered user, and you cannot resolve your technical issues by using the Cisco
TAC website, you can open a case online at this URL:

http://www.cisco.com/en/US/support/index.html

If you have Internet access, we recommend that you open P3 and P4 cases through the Cisco TAC
website so that you can describe the situation in your own words and attach any necessary files.

Cisco TAC Escalation Center

The Cisco TAC Escalation Center addresses priority level 1 or priority level 2 issues. These
classifications are assigned when severe network degradation significantly impacts business operations.
When you contact the TAC Escalation Center with a P1 or P2 problem, a Cisco TAC engineer
automatically opens a case.

1-2

The Skinny Client Control Protocol (SCCP) is the Cisco standard for real-time calls and conferencing
over Internet Protocol (IP). With SCCP, Cisco IP Phones can co-exist in an H.323 environment. When
a Cisco

CallManager is coupled with an H.323 Gatekeeper or an MGCP Call Agent, a Cisco ATA
running SCCP interoperates with H.323 terminals on the far end to establish, control and clear audio
calls.

Figure 1-4 illustrates the architecture of an SCCP network.

button

Chapter 1 Cisco Analog Telephone Adaptor Overview

The unit provides the following connectors and indicators:

• 5V power connector.

• Two RJ-11 FXS (Foreign Exchange Station) ports—The Cisco ATA 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, and both ports can be used simultaneously.

Note The Cisco ATA186-I1 and Cisco ATA188-I1 provide 600-ohm resistive impedance. The Cisco

ATA186-I2 and Cisco ATA188-I2 provide 270 ohm + 750 ohm // 150-nF complex impedance.
The impedance option is requested when you place your order and should match your specific
application. If you are not sure of the applicable configuration, check your country or regional
telephone impedance requirements.

• Ethernet ports

–

The Cisco ATA 186 has one RJ-45 10BASE-T uplink Ethernet port to connect the
Cisco

ATA 186 to a 10/100BASE-T hub or another Ethernet device.

–

The Cisco ATA 188 has two Ethernet ports: an RJ-45 10/100BASE-T uplink port to connect the
Cisco

ATA 188 to a 10/100BASE-T hub or another Ethernet device and an RJ-45
10/100BASE-T data port to connect an Ethernet-capable device, such as a computer, to the
network.

Note The Cisco ATA 188 performs auto-negotiation for duplexity and speed and is capable of 10/100

Mbps, full-duplex operation. The Cisco ATA 186 is fixed at 10 Mbps, half-duplex operation.

• The Cisco ATA 188 RJ-45 LED shows network link and activity. The LED blinks twice when the

Cisco

ATA is first powered on, then turns off if there is no link or activity. The LED blinks to show

network activity and is solid when there is a link.

• The Cisco ATA 186 RJ-45 LED is solid when the Cisco ATA is powered on and blinks to show

network activity.

• Function button—The function button is located on the top panel of the unit (see Figure 1-7).
