BSSAP Tab

The BSSAP+ tab is used to define the radio and transport layers of the Gs interface between the MSC and a 3G-SGSN SUT. The Gs interface allows paging and station availability when it performs data transfer.

The settings for the appropriate protocols are displayed based on your Protocol selection.

In MSC Nodal/MSC Node testing Gs interface defines mapping and transport layers between the SGSN and MSC(VLR) Node.
