IntroductionThis document describes the Multi-purpose Serial Data Link (MSDL) card.
This card provides multiple interface types with four full-duplex serial
I/O ports that can be independently configured for various operations.
Peripheral software downloadedto the MSDL controls functionality for each
port. Synchronous operation is permitted on all MSDL por ts. Port 0 can be
configured as an asynchronous Serial Data Interface (SDI).
An MSDL card occupies one network card slot in Large System Networks,
or Core Network modules and communicates with the CPU overthe CPU
bus and with I/O equipment overits serial por ts. It can coexist with other
cards that support the same functions. For example, cards supported with
the MSDL (NT6D80) are QPC757 (DCHI), QPC513 (ESDI), QPC841 (SDI)
and NTSD12 (DDP).
