Description
Input/Output (I/O) Cards connect the Functional Modules
to external systems and networks. The I/O Cards are hot
swappable cards that are housed behind the Backplane,
opposite the Functional Modules. The I/O Cards are small
and simple and are installed at the rear panel of the MGC.
In the MGC-50 up to eight I/O Cards can be installed in
slots 1 through 8. In the MGC-100 up to 16 I/O Cards can
be installed in slots 1 through 16.
The following I/O cards may be installed in the MCU:
•
The NET IO 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.
•
The IO-4 card connects four PRI/Leased connections
from the MGC rear panel to a Net-4 ISDN/T1-CAS
Network Interface Module.
• The IO-8 card connects eight PRI/Leased connections
from the MGC rear panel to a Net-8 ISDN/T1-CAS
Network Interface Module.
•
The IO-25 Card connects one ATM connection from
the MGC rear panel to an ATM-25 Network Interface
Module.
•
The IO-155 Card connects one ATM connection from
the MGC rear panel to an ATM-155 Network Interface
Module.
•
The LAN-IO Card connects one H.323 connection
from the MGC rear panel to an H.323 Network
Interface Module.
• The Music-IO Card is available on all endpoints and
enables importing audio music from an external
source such as a CD player, tape, radio, etc. It
includes a Line-in jack and headphone output.
