Description

The DSS1 protocol is not a symmetrical protocol i.e. the interface is divided into two sides, one network side and one user side.

The implementation of the network side in MX-ONE Service Node gives the possibility to connect other equipment supporting the DSS1 T-interface user side to the MX-ONE Service Node, i.e video servers other PBX etc.

Figure 1. Transit Scenario between Public ISDN and PBX

This figure describes a transit scenario where MX-ONE Service Node is acting user side towards the public PSTN and network side towards a PBX.
