Access: read-only

Description: Line type. lineTypeBRI(12) - If the physical type is BRI. lineTypeE1(10)/lineTypeT1(11) - For non BRI IF when there are other lines that are already configured to either E1 or T1. lineTypeUnknown(-1) - For non BRI IF when no lines are configured. AC INI-Param: N/A

What is acTrunkLineType?

Reports the detected physical trunk type: BRI (2-wire), E1 (30-channel), or T1 (24-channel), as read-only. Engineers use this to verify hardware configuration matches the logical trunk setup and identify mismatches. A value of 11 confirms the trunk is connected to a T1 circuit with 24 timeslots.
