The measured period from the moment a call or dial-up session is successfully established to the moment it is disconnected. In legacy telephony and dial-up internet, this metric directly determined billing charges. System administrators still track it to monitor resource utilization on remote access servers.
The billing server shows a connect time of 45 minutes for that ISDN call, which explains the high toll charge.
High connect times on a trunk group can indicate stuck channels or users failing to hang up properly.
