QTS

Description

QTS is a hardware/software solution which provides polled Uniscope devices with a cost effective way to be integrated into your TCP/IP network. Connect your existing Uniscopes to a TCP/IP network with our QTS terminal server. Features easy installation, automatic discovery of terminals, powerful local/ remote network management.

Sample QTS configuration

QTS connects to attached Uniscope terminals to the mainframe via HLCs or  DCPs using a single IP address.  QTS converts the Unisys TCP/IP INT1 messages to Uniscope line protocol messages.  In addition to basic polling services, QTS also provides a set of network management services similar in operation to the NMS facility provided by TELCON. These services can be accessed from both the polled terminals and a remote TCP/IP enabled terminal emulator (eg QTerm), giving you the ability to monitor and control QTS regardless of your location on the TCP/IP network.

Note that even though DCP and HLC are shown as host connectivity options, if you connect via a DCP no "terminal handling" is performed there - only transport level or network level routing.

The main objective of QTS is to enable you to connect legacy, polled Uniscope terminals via your newer TCP/IP network but many customers have also seen a performance improvement.  This is simply because the polled link becomes very short (between the QTS and the mux) and the primary network is running at LAN speeds.  Note that all polling is done on this short link so there is no "spoofing" of polls across the TCP/IP backbone network.

Installation and Setup

When purchased as a complete package, no additional hardware or software is required. The complete Plug-n-Play package includes: QTS software, operating system, TCP/IP stack and network interface products, all tested and ready to use.  Please contact Quickware for different packaging options.

Typically you will be installing a QTS to connect to existing wiring on the polled Uniscope side and to a network hub or similar LAN connection on the TCP/IP side.  When you power up the QTS, the software loads and, by default, begins polling the line(s) in automatic discovery mode.  This means that every terminal that responds to poll is automatically detected and built into the poll table.  You can then easily change the line mode and save the terminal configuration.  Then, using a polled terminal or remote TCP/IP terminal emulator, you configure the destination hosts and the legacy terminals can connect to the host.

Network Connectivity

QTS supports a variety of TCP/IP hardware interfaces including:

• Ethernet (Thick, Thin & 10 /100)
• SLIP/PPP
• Token Ring
• FDDI
• ISDN
• X.25

QTS can connect to the host directly via TCP/IP or can be configured to connect via the DCP transport level relay which terminates the TCP/IP connection and opens a DTP/DNS connection to the host.
