21.3.1 ADD-ATCSM

In the first three calls, the control character sequences of the required device types are defined by default values. The type-specific data is then created. Prior to allocating a device, the AMO LCSM (line configuration service module) must be used to create the line-specific data. Since the device data is allocated to the index 2 (TYPENO = 2), the line data must also be assigned to the same index.
