(LAN) or Wide Area Network (WAN). Refer to the OPTIONAL HARDWARE section

of the System Support Addendum (SSA 55.07.13-x) for detailson supported Ethernet,

Token Ring, and asynchronous DECnet configurations.

The PATHWORKS for DOS software can be installed directly on the PC's local hard

disk and used for peer-to-peer DECnet network communications. In this configuration,

server software is not required.

The functions available to the PATHWORKS for DOS user depend largely upon the

configuration of the rest of the network. Each DECnet product offers users its own

level of capability and set of features.

If asynchronous DECnet communication to another DECnet product is required, the

Software Product Description (SPD) for the DECnet product in question must be

consulted to determine if asynchronous operation is supported and to develop a

supportable routing node configuration. Connections over asynchronous terminal lines,

such as to a DECserver 200, are not supported.

PATHWORKS for DOS software is a DECnet Phase IV network product and is

warranted for use only with supported Phase IV products supplied by Digital.

DECnet Phase IV networks can contain a maximum of 1,023 nodes per network area

and up to 63 areas per network. Phase III nodes participating in Phase III/IV networks

are limited to the Phase III routing capability of 255 nodes. Phase IV end nodes not

directly connected to an Ethernet or Token Ring Local Area Network can connect to

only one node (for PATHWORKS for DOS, that node must be Phase IV). In order to

communicate with other nodes in the network, including Phase III nodes, that node

must be a Phase IV full-function (routing) node.

DECnet Phase IV Prime must be used in a Token Ring environment.

PATHWORKS for DOS supports ONE of the following connections on any given

personal computer:

o Direct connections to baseband or twisted pair (10baseT) Ethernet

local area networks via Ethernet controllers. Digital recommends

the use of the multi-buffered DEC EtherWORKS controllers in net-

works that carry heavy traffic.
