Feature Summary

In addition to the new features added to the current release, Solstice X.25 offers the following features:

• A user-friendly GUI based on Motif.

• HTML-based on-line help that provides x25tool specific information.

• A PAD Printer which makes it possible to print locally while logged in to a remote terminal.

• A Call Filtering module filters incoming calls based on specific criteria which are then stored in a configuration file. The criteria you can specify include X.121 address, time of day, call user data.

• The software allows for a total up to 32,763 virtual circuits distributed over any number of links (with a maximum of 4096 virtual circuits on any one line). Machine resources and the configuration of your X.25 network may constrain you to a smaller number.

• Maximum data rates of:

  • 2.048 Mbits per second on one HSI port

  • 1.544 Mbits per second on two HSI ports

  • 19.2 Kbits per second on SPARCstation CPU ports

• X.29 packet-mode host (PAD daemon) and X.3/X.28 virtual terminal (PAD) support.

• Encapsulation of IP packets in X.25 packets, as defined in RFC 1356.

• Address Extension Facility (AEF) for running OSI over X.25.

• Standard configuration file templates for major PSDNs.

• Domain Manager agent (formerly known as SunNet Manager agent).

• Security mechanism (through full or partial address specification) for incoming calls to PAD daemon.

• APIs: STREAMS-based Network Layer Interface and sockets module for backward compatibility with SunNet X.25 7.0.

• The X.25 Packet Layer includes:

  • Extended packet sequence numbering.

  • Large flow control windows (up to 127 packets) and large packet sizes: up to 1024 bytes over 1980-compliant X.25 networks, and up to 4096 bytes over 1984 and 1988 X.25 networks.

• Basic and extended frame sequence numbering for LAPB (1984 and 1988).

• ISO 8208 for DTE-to-DTE operation.

• LLC2 for running X.25 over a LAN (802.x or FDDI)

• Reverse charging, RPOA selection, flow control parameter negotiation, CUG selection, throughput class negotiation, and fast select on a per-call basis.

• Multiple physical links per system. You can have as many connections as serial ports and other resources allow.

• MultiLink Procedure enables more than one physical interface to be used to connect a DTE and a DCE. This allows load sharing and link failure recovery.

• The Data Link Provider Interface (DLPI) is a standard way of writing application programs directly above the datalink layer.

• A client-only implementation of X.32, which provides authentication and is most useful for dial-up calls.

• V.25bis allows Solstice X.25 to be used in dial-up configurations.

• Routing (automatic link selection) among multiple links.

• Configuration files. You can also configure Solstice X.25 9.2 by editing the configuration files delivered with the product. This allows users who do not have access to a Graphical User Interface such as the OpenWindows or Motif environments to carry out a full configuration of the X.25 software.

• The ability to connect to the Defense Data Network via X.25 Standard and Basic Service.
