End-to-End ACK, Full Duplex | Cabletron Systems 1800, FRX4000

BSC Interactive Conﬁguration

End-to-End ACK

This read-only parameter is set to No, and indicates that management of acknowledgments will be handled locally at each end, rather than end-to-end across the network.

Full Duplex

This read-only parameter is set to Yes, and speciÞes full-duplex transmission.

Physical Port Interface

The physical port interface is deÞned by the portÕs connector and cabling type, and must be conÞgured as follows:

¥For the FRX4000 and SmartSwitch 1800, port 0 and port 1 are always RS-232;

¥For the FRX4000, ports 2 and 3 are determined by the attached cables: RS-232, V.35, RS-449, or X.21;

¥For the SmartSwitch 1800, ports 2 and 3 are determined by the attached cables: RS-232, V.35, or RS-449;

¥For the FRX4000, ports 4-7 are determined by the expansion Line Interface Card (LIC) and attached I/O cables. Only the valid interfaces will be listed from the menu button. Possible interfaces are: RS-232, V.35, RS-449, and X.21. (RS-449, and X.21 interfaces require an RS-422 LIC.)

¥For the FRX6000, ports 0-7 on each RLP are determined by the Line Interface Card (LIC) and attached I/O cables. Only the valid interfaces will be listed from the menu button. Possible interfaces are: RS-232, V.35, RS-449, RS-530 and X.21. (RS-449, RS-530, and X.21 interfaces require an RS-422 LIC.)

Blocked Flag

This value will cause the port to be enabled (if No) or disabled (if Yes) when the device is powered up or re-booted.Whichever state is selected, the port will remain in that state until this value is changed or until an enable or disable action is performed. The default value for this parameter is No.

Generate Clock

This setting speciÞes whether the port will generate the clock, or timing, necessary to synchronize trafÞc over the link. If the port is a physical DCE (as determined by the portÕs I/O cable interface), specify Yes, since the physical DCE generates clock. If the port is a physical DTE, specify No. The default value for this parameter is Yes.

Receive Clock from DTE

This parameter is relevant only if Physical Port Interface (see above) is something other than RS-232, and Generate Clock (see above) is set to Yes. If this parameter is set to Yes, it allows the clock (timing) signal to be looped back from the DTE using the Terminal Timing (TT) signal, which can be helpful on high-speed lines.

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.
