Configuring the Subscriber Table

About the Subscriber Table and Subscriber IDs; accessing the Subscriber Table window; adding or modifying a subscriber table entry; editing the Routing and Address tables

The Subscriber Table allows you to add or modify the entries your FRX or SmartSwitch 1800 will use to establish virtual connections to end-user devices in the network. These entries contain the assigned subscriber addresses, as well as information that links those addresses to a speciÞc FRX or SmartSwitch 1800 physical or logical port (or ports). Entries also contain additional information related to preferred delivery algorithms, alternate routing paths, and transmission priority.

The Subscriber Table applies to all serial ports, regardless of protocol; however, it is only

TIP available on devices running Þrmware version 3.3.0 or later.

About Subscriber IDs

Your FRX and SmartSwitch 1800 devices are designed to provide point-to-point dedicated connections among the devices communicating through their serial ports. There are two types of connections used to accomplish this: Permanent Virtual Circuits, or PVCs, which deÞne permanent point-to-point connections which are always available, even when they are not being used; and Switched Virtual Circuits, or SVCs, which are established and broken in response to speciÞc call requests.

Subscriber IDs are used to establish virtual connections between the FRX and end-user devices (or subscribers) in the network. A Subscriber ID is associated with at least one physical or logical port on your FRX or SmartSwitch 1800 device, and includes a number of parameters related to how call requests are routed to that subscriber. The Subscriber Table allows you to conÞgure this subscriber information.

1800, FRX4000, FRX6000 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.
