•Ethernet ports
–
The Cisco ATA 186 has one RJ-45 10BASE-T uplink Ethernet port to connect the
Cisco ATA186 to a 10/100BASE-T hub or another Ethernet d evice.
–
The Cisco ATA 188 has two Ethernet ports: an RJ-45 10/100BASE-T uplink port to connect the
Cisco ATA188 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 Figure1-7).
Figure1-7 Function Button
The function button lights when you pick up the handset of a te lephone 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 “Voice Configuration Menu” section on
page 3-15.
Caution Never press the function button during an upgrade process. Doing so may interfere with the process and
may permanently disable the Cisco ATA.
