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.
