There is a recessed push button located next to the SYSTEM LED.  This button 
allows you to reset the TVP-221H or force the TVP-221H to enter firmware 
upgrade mode.  

To reset the gateway, push a small, stiff object into the hole until the SYSTEM 
LED stops blinking, then release the button. 

Powering on the gateway while pressing down the button for 5 seconds forces the 
TVP-221H to enter download mode 

The rear panel of the TVP-221H has four analog telephony ports, two FXO and 
two FXS ports offering flexible telephony interface usage.  The FXS telephony 
interface ports may be connected to Subscriber Equipment, such as Telephones, 
Fax Machines, Cordless Phones, and Modems. FXO ports can be connected to 
PBX and local phone company Central Office (CO) lines. In addition to analog 
telephony interface ports, there is a power jack for power adapter connection on 
the rear panel.
