Figure 2-10. The Pin Status Window

Each cable pin is represented by a colored rectangle labeled with the pin name; the color-coding tells you whether the pin is active (green; has voltage), inactive (red; has no voltage), unused (tan, or no color), or its electrical status is unknown (yellow). Each serial port provides information about the following pins:

TD (transmit data)

Pin will be active when the connection is operational.

RD (receive data)

Pin will be active when the connection is operational.

RTS (request to send)

For some protocols, the pin will become active when the

 

device wishes to send some data, and become inactive

 

once the data is sent; for a point-to-point protocol,

 

however, the pin will always be active.

CTS (clear to send)

The receiving device has responded to a request to send.

DSR (data set ready)

When active, indicates that the remote data

 

communications equipment (DCE) has signalled that is it

 

ready.

CD (carrier detect)

When active, indicates that the connected line is

 

operational (that is, a dial tone or similar indication is

 

present).

TC (transmit clocking)

When active, indicates that clocking is occurring on the

 

link.

RC (receive clocking)

When active, indicates that clocking is occurring on the

 

link.

DTR (data terminal

When active, indicates that the data terminal equipment

ready)

(DTE) is ready.

TTA (transmit timing)

When active, indicates that timing frames are being

 

transmitted.

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.
