To resolve any differences in addressing conventions, the backup path invokes a trans- lation of the called and calling addresses. The SmartSwitch 1800-compatible called and calling addresses are translated into PDN-compatible called and calling addresses. Node 2 has a translation template defined to intercept packets with the PDN-com- patible calling address for node 1. It translates these into the SmartSwitch 1800-com- patible calling address for node 2. (The backup routing is transparent.)

To display existing translation templates, press [A] at the X.25 Address Translation Templates Menu.

The data between lines is structured to match the headings at the top of the screen.

To add or change a translation template, press [B] at the X.25 Address Translation Templates Menu and enter:

●Port. (The default is 0.) Valid port numbers depend on the model of SmartSwitch

1800—see port locations on page 6-1.

●Direction, I (for incoming packets) or O (for outgoing packets). (The default is I.)

●Template ID, up to 31 characters (including the G and U separators described below), in the format:

aaaaaaaaaaaaaGbbbbbbbbbbbbbbUddddddddddddddd

where:

aaaaaaaaaaaaaais up to 15 digits of called address,

G is the letter "G," which precedes any calling address,

bbbbbbbbbbbbbbis up to 15 digits of calling address, U is the letter "U," which precedes any user data, and ddddddddddd is a user data field of up to 12 numeric characters.

1800 specifications

Cabletron Systems, a leading player in network management and telecommunications solutions during the late 20th century, introduced several innovative products that played a crucial role in shaping enterprise networking. Among these were the Cabletron FRX6000, FRX4000, and the FRX1800, which delivered advanced features aimed at enhancing network performance, security, and scalability.

The Cabletron FRX6000 was designed as a robust multi-layer switch, ideal for large-scale enterprise environments. It supported extensive routing capabilities, allowing organizations to manage traffic efficiently even under heavy loads. The FRX6000 boasted high throughput rates and low latency, making it suitable for demanding applications. With support for various network protocols, including IP, IPX, and AppleTalk, its adaptability made it a versatile choice for diverse networking needs. Moreover, security features like VLAN support and Access Control Lists (ACLs) provided enhanced protection against potential threats.

Moving to the FRX4000, this model offered a balance between performance and cost-effectiveness. The FRX4000 maintained many of the essential features of its larger counterpart while catering to medium-sized enterprises. It provided Layer 3 routing and could handle multiple simultaneous connections, ensuring seamless communication across departments. The modular design allowed for easy upgrades, enabling businesses to expand their network infrastructure without significant overhauls. This made the FRX4000 an attractive option for organizations looking to optimize their network investments.

Lastly, the FRX1800, designed for small to medium businesses, focused on simplicity and ease of use while still incorporating powerful network management capabilities. Its user-friendly interface made it accessible for organizations lacking extensive IT resources. The FRX1800 provided essential functionalities such as Integrated Layer 2 switching and routing, network monitoring, and basic security features, ensuring that even smaller companies could maintain efficient, reliable networking without overwhelming complexity.

All three models utilized advanced technologies, including a high bandwidth backbone and state-of-the-art switching architecture, to enable fast and reliable data transfer. They also supported Quality of Service (QoS) mechanisms, allowing businesses to prioritize critical applications and ensure consistent performance across the network.

In summary, the Cabletron FRX6000, FRX4000, and FRX1800 were pivotal in enhancing network capabilities, providing organizations with scalable, secure, and high-performance options tailored to their specific needs.
