Configuration Examples

Most parameters can be specified and/or changed using the operations described throughout the configuration portion of this manual; others, such as port number, are defined by the hardware or specified during software installation.

Make sure the following are configured in each SmartSwitch 1800:

●Protocols (Chapter 5), to load the serial protocols.

●Physical Port (Chapter 6, plus Chapter 7 [Frame Relay], Chapter 8 [X.25], Chapter 9 [SNA], Chapter 10 [BSC Interactive], Chapter 11 [BSC Batch], Chapter 12 [Async], and Chapter 13 [Voice]).

●Logical Port (Chapter 8) on the physical frame relay port that connects to the network. (Note that logical ports are numbered 8–63, because 0–7 are the physical ports.)

●Voice interface (Chapter 13).

●SVC Subscriber (Chapter 7 [Frame Relay], Chapter 8 [X.25], Chapter 9 [SNA], Chapter 10 [BSC Interactive], Chapter 11 [BSC Batch], Chapter 12 [Async]), and Chapter 13 [Voice]), which assign static addresses used to route the call request packets of the physical access ports to the logical port and vice versa. Subscriber addresses are based on the X.121 Called Address field.

●Optional SVC subscriber records (static routes) for any attached X.25 DTEs. These are needed to identify the attached DTEs’ X.121 Calling Addresses. If an X.25 Call Request is received from the WAN link, the SmartSwitch 1800 needs to know where to route the call.

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.
