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), QPC841 (SDI), and NTSD12
(DDP).
Though the MSDL is designed to coexist with other cards, the number of ports supported by
a system equipped with MSDL cards is potentially four times greater than when using other
