B—Phone 2 connector (RJ-11)
C—10Base-T Ethernet connector
D—12V power connector
Step 1 Place the Cisco ATA 186 near an electrical outlet. Connect the first telephone to
the PHONE 1 input port (A) on the rear panel of the Cisco ATA 186 by using a
telephone line cord with an RJ-11 connector. The PHONE 1 input port will be the
primary telephone line.
Caution Do not connect the Cisco ATA 186 PHONE input ports to the telephone wall
jack. To prevent damage to the device or building telephone wiring, connect
each Cisco ATA 186 PHONE port to a telephone only, never to a telephone
wall jack.
Step 2 You can connect a second telephone to the PHONE 2 input (B) by using a second
telephone line cord. The PHONE 2 input is the secondary telephone line.
Note If you are connecting only one telephone to the Cisco ATA 186, you must use
the PHONE 1 input; otherwise, the telephone cannot place calls.
Step 3 Connect one end of a 10-BaseT Ethernet cable (C) to a hub, switch, or broadband
modem (DSL, cable, and so on).
Step 4 Connect the other end of the Ethernet cable to the RJ-45 input port (C) on the rear
panel of the Cisco ATA 186.
Note Use a crossover Ethernet cable to connect the Cisco ATA 186 to another
Ethernet device (such as a router or PC) without using a hub. Otherwise, use a
straight through Ethernet cable.
Step 5 Plug the AC power adaptor into an electrical outlet. Insert the power cord into the
rear panel of the unit (D). Each connected telephone should ring once, indicating
that the Cisco ATA 186 is powered and ready to use. When the Cisco ATA 186 is
properly connected and powered up, the green activity LED flashes. The activity
LED, labeled ACT, indicates network activity.
