If since system startup there has been no call on this interface, this object has a value of unknown(1).

What is isdnBearerInfoType?

Read-only ISDN bearer capability of the current or last call, such as speech(2) for a voice call, unrestrictedDigital(3)/unrestrictedDigital56(4) for data, or video(8); unknown(1) if there's been no call on this channel since startup - useful for confirming a data line isn't accidentally negotiating as voice.
