1If the Committed Information Rate is set to 0 and the Excess Burst Size is set to a value greater than 0, the DE (Discard Eligibility) bit will be turned on in all received (In) and/ or transmitted (Out) frames.

2CIR = Committed Information Rate. (See first parameter in table.)

3Set Outgoing DLCI Priority to 4 for all Voice DLCIs (DLCIs over which Voice packets will be sent).

4Applicable only on the initiating node. (See explanation.) If configuring a DLCI that will be backed up, you must leave this value at 0 until you have configured a backup group. Then re-enter Port Configuration on this RLP/port/DLCI and specify the desired group. A value of 0 means that the DLCI will not be backed up; therefore, set the Group to 0 if the DLCI will be a backup.

5Specify N for the initiating backup DLCI and Y for the remote backup DLCI.

6Displayed only if Backup Group Number is a value other than 0.

7Valid only if the remote node is an FRX6000 or FRM.

8If set to 65535, switchback will not occur unless the backup fails.

Port Type

specifies the protocol the port will support. Selecting this parameter will display a list of all serial protocols loaded in the SmartSwitch.

Physical Port Interface

must be configured as follows. For reference, port locations are shown on page 6-1.

●Port 0 is always RS-232.

●Port 1 is RS-232or DSU, depending on whether the optional CSU/DSU card is installed.

●Ports 2 and 3 are determined by the attached cables: RS-232 ,V.35, or RS-449.

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.
