To communicate with a mainframe or host computer using a CQ terminal
emulation connectivity solution, the PC or notebook computer running the CQ
software product must be equipped with the proper hardware. In most cases,
the host site almost always determines the connection option for communications
between remote or local workstations and the mainframe computer. For
example, the host site might help to determine the speed (baud rate) of the
connection as the host site ultimately controls this option. Other
factors, such as port availability, type of port, and other factors, are
controlled by the workstation that is connecting with the mainframe.
- Enterprise Extender -
CQ-3770EE® and CQ-3270EE® provide SNA connectivity over
IP connections through the Enterprise Extender (EE) technology. EE
allows for the use of SNA transport protocols (namely APPN and HPR) over an IP
network by the leveraging of IP based infrastructure network components for
use in delivering SNA traffic. Best of all, EE solutions are not
dependent on specific hardware configurations like other SNA connectivity
solutions.
-
Hayes™
OPTIMA™ Modem (with AutoSync™ 2).
These modems support the unique and patented AutoSync 2 feature. This
feature automatically performs the sync/async conversion that is necessary for
synchronous host communications over analog dial-up lines at speeds up to 33.6
Kbps. This feature is unique in that users do not need to open the PC
and install an additional internal synchronous adapter card.
- CQ-Sync100™ PCI Adapter
Card.
This internal 32-bit synchronous adapter card allows PC users to connect
remotely to host computers over analog dial-up or dedicated leased lines at
speeds up to 33.6 Kbps. The card uses an RS-232 cable to connect to an
external synchronous modem.
- CQ-Sync200™ PCI and
CQ-Sync300™ PCI High-Speed Adapter
Cards.
These internal 32-bit high-speed synchronous adapter cards allow PC users to
connect remotely to host computers through two different hardware
configurations. The first configuration uses the adapter cards to
communicate over analog dial-up lines, dedicated leased lines, ISDN lines,
T1/Fractional T1 leased lines, or other connection lines at speeds between
2400 bps and 128 Kbps. The CQ-Sync PCI card is installed
at the remote workstation and is then connected to an
external synchronous modem or
high-speed device. The second configuration uses the adapter cards
and high-speed devices to communicate through a local router over routed
networks.
The CQ-Sync200 PCI adapter card uses an RS-232 cable to
connect to an external synchronous modem or high-speed device (CSU/DSU,
Router, etc.). The CQ-Sync300 PCI adapter card uses a V.35
cable.
- Ethernet NIC or Token Ring Adapter Card
(DLC Interface).
These connections function through internal Network Interface Cards (NICs)
installed in a PC that is part of an Ethernet or Token Ring network. The
solution communicates to the host through a local router over a routed network
(Frame Relay, etc.). This connection option is only available for SNA
products (CQ-3770 and CQ-3270).
- Microsoft Host Integration Server.
This connection allows remote or local host connectivity over TCP/IP, IPX/SPX,
and other network connections. With this connection, the CQ software
operates with Microsoft’s Windows Server Systems™ such as Host Integration
Server 2004 and Host Integration Server 2000. The CQ software can reside
on either the network server PC or a Local Area Network (LAN) network
workstation. This connection option is only available for SNA products (CQ-3770
and CQ-3270).
