Figure 25—IMACS in Video Broadcast Applications
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.
