Need to migrate from X.25 to TCP/IP?
We supply a range of TCP to X.25 Gateway's that also support XOT (X.25 over TCP/IP) and TCP/IP to X.25 data format translation and connection routing.
The FarLinX Mini Gateway is the smallest member of the FarLinX Gateway range - it can handle your smaller scale single X.25 line to TCP/IP migration requirements. It offers many of the same features as in the larger FarLinX X25 Gateway range but at a lower price and in a more compact enclosure. The Gateway supports XOT to X.25 switching, X.25 to TCP data translation and connection routing, TCP to XOT, a Triple-X PAD, and a Host PAD. All this is easily managed from your browser. There are also daily activity logs with a selectable level of detail, automatically archived on a daily basis. The SNMP support provides alerts for a numerous different conditions including critical events such as line down and line up.
The more powerful FarLinX X25 Gateway range is more suitable where multiple and faster X.25 lines are used.
- TCP to X.25 data translation with a very wide variety of modes including: character streaming,
RFC1006, Cisco RBP, APACS, ISO 8583, header stripping and parity conversion and many more
- TCP ↔ X.25 and TCP ↔ XOT routing including: fixed routes, dynamic routing and PAD routing
- Call routing between XOT (X.25 over TCP/IP) and the X.25 line
- X.28 PAD option supporting Telnet and an async connection
- X.25 Host PAD emulation support
- LAN accessible X.25 line as a sharable remotely manageable resource
- Choice of X.25 network interface connections: RS232 (V.24), V.35, RS422, RS530, X.21
- 400 messages per second and up to 50 simultaneous connections (PVC, SVC)
- Line Monitor (local or remote) to view X.25 traffic for easy network problem diagnosis
- Optional support for TCP/IP authentication and data security using IPSEC
- IP and IPv6 support
- Browser graphical configuration, SNMP alerts for critical events and activity logging
- Real time display of current connections, line performance, errors, connections and much more

The FarLinX Mini Gateway provides a reliable means of routing connections between X.25 and XOT (X.25 over TCP/ IP). Connections can be routed between X.25/X.28 and XOT which is treated as another connection path. The connection routing module supports default routes, hunt groups, X.25 address translation, and routing commands with NUA wildcards for maximum flexibility.
Up to 50 SVC or PVC sessions can be handled simultaneously over XOT and the X.25 line.
The Gateway provides connection establishment and data packetization services to allow applications sending data over TCP/IP to interface to X.25 or XOT connected hosts. The Gateway provides routing facilities to select the appropriate Host from those available and maintains X.25 or XOT sessions to the Host as required.
Up to 50 SVC or PVC sessions can be handled simultaneously between TCP/IP and X.25 or XOT.
TCP to X.25 or XOT data translation functions
The Gateway supports a wide range of TCP to X.25 or XOT data translation and connection functions, these include:
- Character stream
- ETX terminated messages
- Special character terminated messages (customisable)
- Message header conversion - types available 2 or 4 byte ASCII or Binary length representation
- Custom message header conversion
- RFC1006 - ISO Transport Class 0 protocol data units, using the RFC-1006 encapsulation on the TCP connection
- Cisco RBP - Record Boundary Preservation
- X.25 Parity conversion - the Gateway performs any required parity adjustments and removal on the X.25 / XOT connection
- POS protocols APACS, ISO 8583, HGEPOS plus CTL (Card Tech Ltd) - Requires the POS Firmware Option
Connection Routing and Address Mapping
The FarLinX Mini Gateway can support routes to hundreds of different X.25 / XOT hosts. Similarly, when using the
called X.25 address as the routing key, incoming X.25 / XOT calls can be routed to hundreds of different TCP/IP
When making connections to the X.25 network or XOT, the Gateway has the capability of mapping the source IP address to a calling X.25 address, thus allowing the destination X.25 / XOT host to identify the connection source uniquely.
The Dynamic routing options allow the X.25 address (NUA) and call parameters to be set by the remote application at the time each X.25 / XOT connection is established. These modes allow X.25 packetisation information to be passed to the application. Linux and Windows sample applications provided.
The main modes supported include:
- Statically defined routing
- XDRPD (eXtended Dynamic Routing Packetized Data) and DRPD - these formats allow TCP connected applications to dynamically setup and control the X.25 or XOT connection
- X.25 Data Switching - allows X.25 devices to be interconnected via an IP network without the overheads associated with XOT
- PAD Routing - PAD or Dynamic routing may be employed to allow the TCP client application to specify the X.25 call parameters
X.28 Host Pad
The FarLinX Mini Gateway can be configured to act as an X.28 host PAD for remote terminals or applications connecting over X.25 and expecting a host that supports X.28. The host PAD sends X.28 PAD configuration commands over X.25 to the connecting terminals. The host PAD profile is configurable.
X.28 Triple-X PAD
Triple-X PAD (X.28, X.3 and X.29) support is included with the Gateway, and is accessible over TCP/IP via Telnet or using the single permanent async port. The connecting terminal is presented with a Triple-X PAD service and can be used to make X.25 connections over the physical X.25 line or via XOT connections to remote hosts. The initial PAD profiles for the async port and for the Telnet access are fully configurable.
Available as an option at the time of ordering, the FarLinX Mini Gateway can be supplied with an IPSEC capability that can provide communications security in IP networks. This can be especially important when public Internet connections are used for part of the communications path.
IPSEC operates between a pair of devices. Each must know details of the remote device in order to authenticate communications and successfully encrypt/decrypt data being sent and received. In the case of the FarLinX Mini Gateway, the details of multiple partner Gateways can be configured. The pre-shared key used to authenticate is unique for each remote partner. Once authentication has completed an exchange of encryption keys takes place under the pre-shared key. The session key is used only for a single session.
FarLinX Gateway models without IPSEC can be supplied to any country. Models with IPSEC capability can be exported without a special export licence to some countries. Where IPSEC is required and the destination country is not on the pre-approved list, FarSite will apply for an export license for that customer. See Order Information for more details.
The Gateway is configured from a Browser - IE, Firefox and Chrome are all supported. Access to the configuration is secured through a user name and password.
The Configuration Application allows all the features of the Gateway to be managed. The majority of configuration changes to the Gateway are made dynamically so continuous operation of the Gateway can be maintained.
See a sample screen of the X.25 configuration on the right.
Configurations can be saved for later use.
Upgrades to the firmware can be remotely and securely uploaded to the device to allow the latest revision firmware to be used. Rollback to a previous version is supported.
The gateway maintains a comprehensive set of statistics and activity counts. This information can be used to indicate the total loads on the Gateway and also to give early warning of line performance problems and even misconfigured systems elsewhere in the network.
All connections setup through the Gateway can be logged. The logs are automatically saved on a daily basis. Old logs can be displayed as required. Log events can also be routed to syslog to allow logging centrally.
The connection status of active connections / most recent connections / disconnections are displayed in a browser window.
The Gateway supports SNMP alerts with 3 configurable levels. Alerts can be issued for SVCs connecting and disconnecting, PVC errors, connection routing errors, line up and line down events and many more events.
The Gateway includes Line Monitor software installable from CD onto a Windows PC. This allows X.25 traffic to be recorded and displayed in real time. Multiple Gateways can be monitored simultaneously. Support to allow the popular Wireshark line monitor to record and display the X.25, TCP/IP and XOT line traffic is also included.
This very useful feature allows Network Managers and System Installers to locally or remotely analyse and rapidly diagnose problems that may occur on the X.25 lines without the need for expensive external line monitors.
The line traces can be saved and viewed later, for example in a customer support situation.
FarSite recognises that this product is frequently used as a key component in networked systems and as such a guaranteed response to unexpected problems is required. Maintenance contracts are available for the FarLinX Mini Gateway for fast hardware swap out, firmware upgrades, priority service and rapid problem resolution.
