Migration From DS/3000 to NS 3000/iX Network Services
Differences Between DS/3000 and NS 3000/iX
Differences Between DS/3000 and
NS 3000/iX
DS is an acronym for Distributed Systems.
NS is an acronym for Network Services. An NS 3000/iX link product is
required in addition to the NS 3000/iX Network Services.
A DS installation can consist of 1) hardwired point-to-point links, 2)
point-to-point modem links on either dial-up or leased telephone lines,
3) X.25 network links, and 4) satellite network links. The maximum
data rate over a DS link is 56 kilobits per second.
An NS installation, on the other hand, may be an internetwork
consisting of a LAN with a 10 megabit-per-second signalling rate
connected to other LANs by way of a wide-area, point-to-point network
link. NS 3000/iX cannot directly access a DS link. However, an
NS 3000/V node can be used as an intermediary to connect from an
NS 3000/iX node to a DS link.
New Features
NS 3000/iX provides the user and programmer with many features that
are not available in DS/3000. These new features are summarized here:
• Direct access to any node on the network or internetwork.
• Direct access to remote files, devices, or databases.
• Configurable remote prompts.
• Redirection of node names coded into programs or job streams.
• Programmatic access of remote terminals by using Reverse VT.
• Network File Transfers (NFT) from any node on the network or
internetwork to any other node on the network or internetwork.
• Temporary remote logons for NFT transfers.
• DSCOPY options to move, replace, or overwrite files and to copy
privileged files.
• New and existing (DS) syntax is supported.
