1.1 About the MC1 Board
- The MC1 board is an MVIP multi-chassis interconnect card which conforms to the MC1 specification and contains an MVIP switch.
- MC1 boards resident in different PCs are connected by an MC1 bus cable. The MC1 board switches data between the MVIP-90 bus and the MC1 bus allowing MVIP boards in one PC to communicate with MVIP boards in another PC.
Figure 1. An Example MC1 System
- The MC1 board resides in an ISA standard bus slot and connects to the MVIP-90 bus using a 40-conductor ribbon cable (MVIP-90 bus cable). MC1 boards are connected together with a SCSI-3 type cable. The two ends of the MC1 bus are terminated with a SCSI-3 terminator.
- The maximum length of the MC1 cable is 15 meters. Each MC1 node must be at least 0.3 meters apart. The MC1 board has been tested in systems with up to 15 nodes.
1.1.1 MC1 Board Components
Figure 2. MC1 Board Components
- The main components of the MC1 board are:
Each MC1 board is designed to reside in a single 16-bit ISA bus slot.
- MVIP-90 Bus Connectivity
The MC1 board provides full support of the MVIP-90 bus specification. The MVIP-90 bus allows boards to share data with other boards on the MVIP bus.
- MC1 Bus Connectivity
The MC1 board provides full support for the MC1 bus specification. The MC1 bus allows MVIP boards to share data with other MVIP boards in other PC chassis on the MC1 bus.
- Telephony Bus Switching
The switching for the MC1 board is implemented using two FMIC (Flexible MVIP Integrated Circuit) chips. The FMIC is a single chip that offers full support for the MVIP-90 bus and provides access to all 512 slots on the
MVIP-90 bus. On the MC1 bus, switch connections are allowed for up to 256 full-duplex connections.
1.2 Application Development Software Packages
- MC1 applications may be built using CT Access or AG Access. MC1 board configuration and MC1 clock configuration is supported by sending commands to the MC1 driver or by using the MC1 utility, mc1mon.
1.2.1 About CT Access
- CT Access is a complete development environment for telephony applications. It provides a standard set of telephony functions grouped into logical services. Each service has a standard programming interface. CT Access services include call control, DTMF generation and detection, and voice playing and recording.
- CT Access includes a Switching service which controls switching on MVIP compliant devices. This service is used to make or break connections, to send patterns, and to sample data. The Switching service supports both MVIP-90 and MVIP-95 specifications. For more information on CT Access, see the CT Access Developer's Reference Manual.

1.2.2 About AG Access
- AG Access is a library of functions for controlling telephony operations on AG boards. AG Access provides functions for call control, DTMF generation and detection, and voice playing and recording.
- To control switching in AG Access applications, you can use the SwitchPath library of switching functions, or the SW Utility. SwitchPath and the SW Utility support only MVIP-90 specifications. Using SwitchPath, the MC1 driver commands can be sent to configure the MC1 board and configure the MC1 clocking.
- For more information on AG Access, see the AG Access Developer's Manual.
