Interoperability With MVIP-90

The AG Quad board is located in a PCI bus slot and connects to the H.100 telephony bus. MVIP-90 and H-MVIP boards connect to the MVIP-90 bus and are typically located in ISA bus slots.

The MVIP Bus Adapter is an adapter which connects the H.100 bus to the
MVIP-90 bus located in the same computer chassis as shown in Figure 29.

Figure 29. H.100 Bus Interoperability with MVIP-90 Bus

The MVIP Bus Adapter allows boards connected to the H.100 bus to access the MVIP-90 bus, and allows MVIP-90 boards to access the first 16 streams of the H.100 bus. When connecting H.100 boards to the adapter, configure the first 16 H.100 streams in MVIP-90 mode.

The H.100 streams running in MVIP-90 mode are clocked at 2 MHz. Each stream has 32 timeslots. By default, the AG Quad board is configured for MVIP-90 compatibility mode with the first 16 streams configured for 2 MHz.

Figure 30. MVIP Bus Adapter Streams

Connecting to the MVIP-90 Bus

The MVIP Bus Adapter is an adapter that connects the H.100 bus to the MVIP-90 bus. This allows boards connected to the H.100 bus to access the MVIP-90 bus, and allows MVIP-90 boards to access the first 16 streams of the H.100 bus. When connecting to the MVIP Bus Adapter, the first 16 streams of the H.100 bus must be configured to run in MVIP-90 mode (clocked at 2 MHz).

The MVIP Bus Adapter (shown in Figure 31) contains a connector to an H.100 board (such as the AG Quad) and the MVIP-90 bus.

Figure 31. MVIP Bus Adapter

If your system contains an AG Quad board and MVIP-90 boards, you must use the MVIP Bus Adapter. The MVIP Bus Adapter connects the MVIP-90 bus to the H.100 bus as shown in Figure 32. Only one MVIP Bus Adapter is required in a system.

Figure 32. Connecting to the MVIP-90 Bus

To connect the MVIP Bus Adapter, refer to Figure 33 and follow this procedure:

1. Connect the right angle connector (JP1) on the MVIP Bus Adapter to the connector (JP6) on the AG Quad board.

2. Support the MVIP Bus Adapter by connecting the threaded mounting piece to the MVIP Bus Adapter and the AG Quad board using two #4 screws.

3. If you have multiple H.100 boards, connect the H.100 bus cable to the AG Quad board and to each of the other H.100 boards.

4. Connect the MVIP-90 bus cable to the connector on the MVIP Bus Adapter.

Compliance and Regulatory Certification

Natural MicroSystems obtains board-level approvals certificates for supported countries. In addition to the approval obtained by NMS for the board and its associated software, some countries require a system level approval before connecting the system to the public network. To learn what approvals you require, contact the appropriate regulatory authority in the target country.
