Phone S0 is always fixed to connect ISDN phone. However, ISDN /Phone S0 is
configurable as NT or TE mode. When the user configures ISDN /Phone S0 as NT mode
in VoIP>> Phone Settings, the orange LED will light on to indicate ISDN-NT is
selected. And by using ISDN phone adapters (coming from the router package), the user
can connect several phones to Vigor2820VS for communication. Refer to the following
