Figure 4 Cabling the Cisco ATA 186
Figure 5 Cabling the Cisco ATA 188
Refer to the appropriate illustration and follow these steps to install your ATA:
Procedure
Step 1 Place the Cisco ATA near an electrical power outlet.
Step 2 Connect one end of a telephone line cord to the Phone 1 input on the rear panel of the Cisco ATA. Connect the other end to an analog telephone set.
If you are connecting a telephone set that was previously connected to an active telephone line, unplug the telephone line cord from the wall jack and plug it into the Phone 1 input.
Warning To reduce the risk of fire, use only No. 26 AWG or larger telecommunication line cord.
Caution Do not connect the Phone input ports to a telephone wall jack. To avoid damaging the Cisco ATA or telephone wiring in the building, do not connect the Cisco ATA to the telecommunications network. Connect the Phone port to a telephone only, never to a telephone wall jack.
Note The telephone must be switched to tone setting (not pulse) for the Cisco ATA to operate properly.
Step 3 (Optional) Connect the telephone line cord of a second telephone to the Phone 2 input port.
Note If you are connecting only one telephone to the Cisco ATA, you must use the Phone 1 input port.
Step 4 Connect an Ethernet cable to the uplink RJ-45 connector on the Cisco ATA. For the Cisco ATA 186, this is the 10BASE-T connector; for the Cisco ATA 188, this is the 10/100UPLINK connector.
Step 5 (Cisco ATA 188 only—optional) Connect a straight-through Ethernet cable from your PC to the 10/100 PC RJ-45 connector on the Cisco ATA.
Step 6 Connect the socket end of the power cord to the 5V DC power adaptor.
Step 7 Insert the power adaptor cable into the power connector on the Cisco ATA.
Warning This product relies on the building's installation for short-circuit (overcurrent) protection. Ensure that a fuse or circuit breaker no larger than 120 VAC, 15A U.S. (240VAC, 10A international) is used on the phase conductors (all current-carrying conductors).
Step 8 Connect the plug end of the 5V DC power adaptor cord into an electrical power outlet.
When the Cisco ATA is properly connected and powered up, the green activity LED flashes to indicate network activity. This LED is labeled ACT on the rear panel of the Cisco ATA 186 and is labeled LINK on the rear panel of the Cisco ATA 188.
Caution Do not cover or block the air vents on either the top or the bottom surface of the Cisco ATA. Overheating can cause permanent damage to the unit.
Power-Down Procedure
Caution If you need to power down Cisco ATA 186 or Cisco 188 at any time, use the following power-down procedure to prevent damage to the unit.
Procedure
Step 1 Unplug the RJ45 Ethernet cable
Step 2 Wait for 20 seconds.
Step 3 Unplug the power cable.
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 6).
Figure 6 Cisco ATA Function Button
The function button lights when you pick up the handset of a telephone attached to the Cisco ATA. The button blinks quickly when the Cisco ATA is upgrading its configuration.
Note If the function button blinks slowly, the Cisco ATA cannot find the DHCP server. Check your Ethernet connections and make sure the DHCP server is available.
Pressing the function button allows you to access to the voice configuration menu. For additional information about the voice configuration menu, see the information about the voice configuration menu in your administrator's guide.
Caution Never press the function button during an upgrade process. Doing so may interfere with the process and may permanently disable the Cisco ATA.
3 Configuration
For complete configuration information, see the administrator's guide for the signaling image protocol you are using (SCCP, MGCP, H.323 or SIP). The Cisco ATA administrator's guides are located at the following URL:
http://www.cisco.com/univercd/cc/td/doc/product/voice/ata/ataadmn/index.htm
Making a Call
Lift the telephone handset. Make a call as you normally do. You will hear ringing if the called party is available. When the called party answers, speak normally and hang up when finished. You can cancel or discontinue your call at any time by hanging up the handset. You can make a separate, simultaneous telephone call by using the second handset connected to the ATA.
Note Your service provider or system administrator might offer a different dial plan. If you cannot place calls using the preceding instructions, contact your service provider or system administrator for assistance.
Troubleshooting Tips
The suggestions in this section are general troubleshooting tips.
•Make sure that the DHCP server is operating correctly. Note that the function button blinks slowly when the Cisco ATA attempts to acquire the DHCP configuration.
•If the green activity LED is not flashing after you connect the Ethernet cable, make sure that both the power cord and the Ethernet connection are secure.
•If there is no dial tone, make sure that the telephone line cord from the telephone is plugged into the appropriate port on the Cisco ATA. Make sure that your Cisco ATA is properly registered on your Call Control system. Test another phone; if this phone does not work either, there may be a problem with the current configuration or with the Cisco ATA.
•A busy tone indicates that the party you called is not available. Try your call again later. A fast-busy tone indicates that you dialed an invalid number.
•After power up, if the function button continues to blink slowly, the Cisco ATA cannot locate the DHCP server. Check the Ethernet connection and the availability of the DHCP server.
•The DHCP server should show an incoming request from the MAC address listed on the product label or given by the voice prompt.
Note Customers who obtained their equipment through service providers, independent dealers and other third parties must contact their equipment provider for technical assistance.
