Telephony Interface Type

Frame relay

is transmission of data in a format that combines level 2 and level 3 functionality, but provides connection information only for level 2.

FRX

is a Cabletron product line (FRX4000, FRX6000) that can connect to and interact with a SmartSwitch 1800. The full names for these products are Netlink FRX4000 and Netlink FRX6000.

FXO

is a voice configuration that interfaces with two-wire telco switching equipment; e.g., a central office or the station side of an analog PBX. The SmartSwitch 1800 can be

configured for FXO by setting the Voice port parameterto OPX.

FXS

is a voice configuration that interfaces with two-wire telco equipment such as tele- phones. The SmartSwitch 1800 can be configured for FXS by setting the Voice port parameter Telephony Interface Type to SLT.

G

Gateway

is a port that provides access to a “foreign” network (one that is not part of the local network).

H

HPAD

is an integral (to a SmartSwitch 1800) SNA or BSC PAD connected to a host.

Hunt group

is a designated group of ports that share incoming calls according to a pre-defined algorithm.

I

ICMP

stands for “internet control message protocol,” which handles IP error and control messages. Gateways and hosts use ICMP to report problems concerning datagrams back to the source.

Internet

is an interconnected group of packet-switching networks, joined by gateways sup- porting the TCP/IP protocol. The term also refers to the DARPA (Defense Advanced Projects Research Agency) Internet.

Internet Protocol

is the Internet standard protocol that defines the datagram as the basic unit of data transmitted across the internet.

IP

stands for “internet protocol.”

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.
