Such information is provided for Vigor2930 S models (e.g., Vigor2930VS).
ISDN S0 1 is always fixed to connect ISDN phone. However, ISDN S0 2 is configurable
as NT (ISDN S0 intern) or TE (ISDN S0 extern) mode. When the user configures ISDN
S0 2 as NT mode in VoIP>> Phone Settings, the orange LED will light on to indicate
ISDN2-S0 is selected. And by using ISDN phone adapters (coming from the router
package), the user can connect several phones to Vigor2930VS for communication.
Refer to the following figure for reference.
Yet, if the user configures ISDN S0 2 as TE Mode in VoIP>> Phone Settings, the green
LED will light on to indicate ISDN2-TE is selected. Then, the port is specified for ISDN
line only. Refer to the following figure for reference.
