6.1 Configuring Links on the Ater InterfaceThis topic describes how to configure links on the Ater interface for the signaling transmissionbetween the GMPS or the GEPS and the GTCS. The links on the Ater interface are the Aterconnection path, Ater OML, and Ater signaling link.

1. 6.1.1 Configuring the Ater Connection PathThis topic describes how to configure the connection path between the GMPS and the GTCSas well as between the GEPS and the GTCS on the Ater interface.

2. 6.1.2 Adding an Ater OMLWhen the GTCS is configured on the MSC side, you have to add an Ater OML betweenthe GMPS and the main GTCS. The Ater OML transmits the OM information to the GTCS.
