6.3 Compatibility with other MSI boards

The MSI board feature set is based on the Dialogic MSI-C board and its hardware design enables the MSI to take advantage of the Board Locator Technology (BLT) circuit, programmable interrupts, and shared RAM interface.

Using the MSI, developers can build large call center configurations without the need for DMX boards or crossover cables. Other significant differences between the MSI and the MSI-C board include:

• Relay interlock for loop and ring voltages (Only on the MSI/SC-R boards)
• Ability to ring 2500-type telephones
• On-board ring voltage generator (Only on the MSI/SC-R boards)
• Ringing SLICs (Subscriber Line Interface Circuits) (MSI/SC-Global and MSI/PCI-Global boards)
• Use of the 1024 time slots available on the SCbus

Conference-specific differences between the MSI boards and the MSI-C board include:

• Pupil/coach feature
• Hidden training
• Extended connections
