between  MSC  and  SIWF Server

specified from  GSM Rel-96 to GSM Rel-98
Source:   GSM 03.02, Rel-98 

The link between the visited MSC and the SIWFS supports signalling functions and functions for the transport of traffic. In addition the link supports signalling functions to control the SIWFS i.e. IWU located in the selected SIWFS.

The traffic channel supports that a circuit will be used to send and receive data in the A interface format and will be called 'a' circuit. Another circuit will be used to send and receive data in the format of the fixednetwork and will be called 'n' circuit. The circuits 'a' and 'n' consist of one 64kbps channel each.

The signalling channel supports e. g. ISUP i.e. the signalling between the visited MSC and the SIWFS by using e. g. ISUP. The checking and the mapping of information element parameters of the GSM 04.08 signalling take place in the visited MSC in accordance with GSM 09.07.

The K interface is specified in GSM 03.54.
