Asynchronous Wide Area Network (AWAN) Server
Connections
The SWAN 2 concentrator is a next-generation SWAN concentrator. The SWAN 2
concentrator is based on a faster processor.
Asynchronous Wide Area Network (AWAN) Server Connections
AWAN servers are optional products that provide local and remote asynchronous
access to an HP NonStop S-Series server or K-series server, and other LAN-based
resources. An AWAN server establishes a TN6530 session for 6530 applications or a
standard TELNET session for OSS applications on behalf of the asynchronous
terminal. The HP NonStop TCP/IP subsystem and Telserv software are required for
such sessions. AWAN servers also support serial printers using HP FASTPTCP
Spooler print process software. Serial printers are connected using RS-232 direct
connections.
There are two families of AWAN servers that are available:
•
AWAN Access Servers (3883, 3884, 3885)—are local area network (LAN)-based
communications devices that provide asynchronous connections to HP 6530
terminals, 6530-compatible terminals, VT-series terminals, serial printers, and
workstation-based 6530 and VT-series terminal emulators for NonStop S-Series
and K-series servers. These servers supports multiple protocols, enabling users to
connect to the AWAN access server simultaneously using different types of
protocols.
For more information about these servers, see the AWAN 3883/4/5 Access Server
Configuration and Management Manual and the AWAN 3883/4/5 Access Server
Installation and Support Guide.
•
3886 AWAN Servers (3886-08, 3886-16, 3886-32)—are similar in function to the
AWAN Access Servers; the 3886 AWAN Servers are a local area network
(LAN)-based communications devices that provide asynchronous connections to
terminals, serial printers, and workstation-based 6530 and VT-series terminal
emulator for NonStop S-Series and K-series servers. A 16-port current loop
module for AWAN 3886-16 and 3886-32 servers is also available. AWAN support is
enabled by inserting a 3886-6530 flash RAM card.
For more information on AWAN 3886 servers, see the AWAN 3886 Server
Installation and Configuration Guide.
Both families of AWAN servers support:
•
The HP Tandem Transparent Protocol (TTAP)
•
Non-TTAP printers
•
NonStop K-series and NonStop S-Series systems
•
Current loop
All AWAN servers also support HP ATP6100 if GAP, a third-party product, is used.
GAP was developed by Gemini Communications (http://www.geminic.com).
