How many boards and channels can be supported by a single-computer system?
A single computer can accommodate more than 10 boards (can be of different models). A single computer with all analog boards gives up to ‘number of boards×16’ channels, one with all digital PCI boards gives up to ‘number of boards×240’ channels (for boards with 8 E1) and one with all digital cPCI boards gives up to ‘number of boards×480’ channels (for boards with 16 E1).
