Jitter

specifies the amount of jitter delay, which is used to compensate for the variable arrival time of frames. Inconsistent arrival can result in a choppy voice quality. Increasing the jitter buffer size will increase the end-to-end delay, but will insure smoother voice quality.

Call Timer

is the amount of time the SmartSwitch 1800 will wait for a response to a Call Connect or Call Clear request. When the SmartSwitch issues the Call Connect or Call Clear request, it will set a timer to the value configured here. If that timer expires with no response from the destination, the SmartSwitch will generate a busy tone.

Long Dial Prefix

is a character that will be required preceding calls using the long-call format (i .e., when a speed-dial number is not used). When the user at an attached device (e.g., tele- phone or Fax machine) dials a long-form number, s/he must precede the number by the Long Dial Prefix.

Selecting this parameter will display a table of the following values. Specify a value by entering the corresponding letter from that table:

A = 0

D = 3

G =6

J = 9

B = 1

E = 4

H = 7

K = * (asterisk)

C = 2

F = 5

I = 8

L = #

Suppression

is a level of suppression of background noise. For most calls, low suppression (2) should be sufficient. The higher the suppression level, the greater the possibility that low-volume voice will be lost; therefore, suppression levels higher than 2 should be used only if it can be certain that background noise will be low or all of the voice trans- mitted will be sufficiently louder than the background noise.

1

= no suppression

2

= low suppression

3 = medium suppression

4

= high suppression

5

= very high suppression.

 

A larger suppression level saves composite bandwidth, allowing more data channels to operate simultaneously with voice channels.

Auto Dial Parameters

Auto Dial

Enables or disables the auto-dial feature of the SmartSwitch 1800. If auto-dialing is enabled, the SmartSwitch 1800 will dial configured Auto Dial Number when the handset attached to this Voice port is taken off-hook.

Enabling this parameter will disable the variable length dialing feature for this channel, regardless of the Dial Timer setting.

Auto Dial Number

is a number to which the SmartSwitch 1800 will attempt to connect when the handset (or its equivalent) attached to this port is taken off-hook, if Auto Dial is set to Y.

The SmartSwitch will automatically dial the long-form number defined in the speed- dial map table configuration that is associated with the speed dial number specified here.

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.
