Using the Reset Button

Use the

Reset

button, on the back of the Telephony Gateway, to reset the modem

and perform initialization as if you power cycled the unit. You may need to reset the

Telephony Gateway if you are having problems connecting to the Internet. Using

this button will be rare.

Use a pointed

non-metallic

object to press this button. The photo to the left shows

the location of the

Reset

button. The

Reset

button is recessed to prevent acci-

dental resets.

The diagram on the left shows the location of the reset button.

Resetting the Router to Factory Defaults

To reset the router to factory defaults, press and hold the

Reset

but ton on the back

of the Telephony Gateway for more than ﬁfteen seconds. This restores the wireless

setup conﬁguration and router conﬁguration parameters to the factory defaults. You

may need to do this if a misconﬁguration has locked out all access.

Booting from Battery

The TG1682 supports a “Boot from Battery” feature that allows the Telephony Gate-

way to provide voice service without AC power.

To start the TG1682 from its battery, follow these steps:

1

If a battery is already installed in the Telephony Gateway, remove it.

2

Re-insert the battery into the Telephony Gateway (see

Battery Installation

and Removal

for details).

3

Press the

Reset

button; the Power light should turn on immediately.

Troubleshooting

The Telephony Gateway is plugged in, but the Power light is off.

Check all power connections. Is the power cord plugged in ﬁrmly at both

ends?

If you plugged the power cord into a power strip, make sure the strip is

switched on.

Avoid using an outlet controlled by a wall switch, if possible.

Finally, check the fuse or circuit breaker panel.

I’m not getting on the Internet (all connections).

It may take over 30 minutes to establish a connection the ﬁrst time you

power up your Telephony Gateway, especially when many people are online.

Always leave your Telephony Gateway plugged into AC power and connected

to the cable system.

Check the front panel lights:

•

The

Power

and

Online

lights should be on.

•

If the

Power

light blinks for more than 30 minutes, call your cable

company for assistance.

Check your cable connections. Connectors should be tight. The

coax cable

should not be pinched, kinked, or bent sharply—any of these can cause a

break or short in the cable (you may have to replace the cable). If you have

one or more splitters between the Telephony Gateway and CATV outlet, re-

move the splitters and connect the Telephony Gateway directly to the out-

let.

Proceed to the Ethernet or wireless solutions (next page) if necessary.
