Input/Output Cards
Input/Output (I/O) Cards connect the Functional Modules to external systems
and networks. The I/O Cards are housed behind the Backplane, opposite the
Functional Modules.
The I/O Cards, which are small and simple, are installed via the rear panel of
the MGC. A connector at the rear of each I/O card connects the card to the
Backplane. 0
The following I/O cards may be installed in the MCU:
• The NETIO card connects two PRI/Leased connections from the MGC
rear panel to a Net-E1/Net-T1 ISDN Network Interface Module.
• The IO-2 card connects two PRI/Leased connections from the MGC rear
panel to a Net-2 ISDN/T1-CAS Network Interface Module.
