Integrated ISDN Access with SINA

The IMACS is used to support both ISDN and non-ISDN services over the same T1/E1 circuit. This multiplexing of leased line and ISDN services is commonly referred to as Static Integrated Network Access (SINA).

As shown in Figure 26, several non-ISDN applications are used including analog voice and data applications, low speed SNA data, and non-ISDN PBXs. Several ISDN based applications are being used including video- conferencing, dial routers, and an ISDN PBX. The non-ISDN circuits are groomed onto the T1/E1 circuit for delivery to the network. ISDN applications are sent to the PRI Server card for concentration and are switched onto the same T1/E1 circuit in time slots appropriate for switched ISDN calls. Within the network, these circuits are groomed via a cross-connect to the appropriate services.
