Configuring Async PAD Profiles

An async PAD profile is a specific set of X.3 parameters whose values define the oper- ation of the device connected to an async PAD port on a SmartSwitch 1800. Different profiles contain the same parameters, but with difference(s) in the values.

To display a list of existing PAD profile names and descriptions, press [A] at the Async PAD Configuration Menu (or [A], [A], [F], [A] from the Main Menu). Note that the database contains one profile, 90, which is a CCITT profile used for connecting ter- minals to the PAD.

Changing a value in a profile in effect creates a new profile. Unless you want to affect every device assigned that profile, create a new profile instead of changing an existing one. Do not change profile 90, since this is a CCITT standard.

To add or change a profile, press [B] at the Async PAD Configuration Menu and enter the desired profile name (1–10 uppercase characters) to display the first of two screens of parameters, listed in Table 12-1. Press [PgDn] at the first screen to display the second screen. Press [PgUp] at the second screen to return to the first screen, or [F3] to return to the Node Configuration Menu.

When creating a new profile, be careful that you are not creating a duplicate of an existing profile. When assigning a profile to a port, the software scans the parameters of the specified profile and all other existing profiles, and if there are duplicates, it loads the profile that was created first.

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.
