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.
