Introduction
This 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 downloaded to the MSDL controls functionality for
each port. Synchronous operation is permitted on all MSDL ports. Port 0
can be configured as an asynchronous Serial Data Interface (SDI).
An MSDL card occupies one network card slot in Large SystemNetworks,
or Core Network modules and communicates with the CPU over the CPU
bus and with I/O equipment over its serial ports. 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).
