Cable Modem Start Up Sequence
The following table shows the start-up sequence for the cable modem portion of the
Telephony Modem. Indicator color is not important.
Using the Reset Button
Use the
Reset
button, on the back of the Telephony Modem, to reset the modem
as if you power cycled the unit. You may need to reset the Telephony Modem 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.
Booting from Battery
The TM822 supports a “Boot from Battery” feature that allows the Telephony Modem
to begin service without AC power.
To start the TM822 from its battery, follow these steps:
1
If a battery is already installed in the Telephony Modem, remove it.
2
Re-insert the battery into the Telephony Modem (see
Battery Installation
and Replacement (TM822G Only)
for details).
3
Press the
Reset
button; the Power light should turn on immediately.
