So if my understanding is correct, Energy Saving mode exists in P2P BRI lines. How do you monitor these lines ? By monitoring, I mean "getting an SNMP trap when the line is going down", for instance. Maybe I should just convince myself that I should not check anymore line status looking a flag updated in real time, but simply trying to send an outgoing call as I would with analog lines. > P2MP does have an energy saving mode which depends on the PSTN and on the > TE device.
