SLT Timeout, Jitter, Sample Delay | Cabletron Systems FRX6000, 1800

SmartSwitch 1800 Voice Conﬁguration

SLT Timeout

This is the time (in seconds) the local voice port will wait before an actual fax transmission begins. If there is no fax tone when this timer expires, the connection will be terminated. The default value for this parameter is 30.

Jitter

This Þeld speciÞes the amount of jitter delay (in 5-millisecond increments), 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.

Sample Delay

This Þeld speciÞes the amount of sample delay.

Level In

This speciÞes the local voice level into the voice port. This parameter adjusts the sensitivity of the local voice channel to the signal from the attached device. The purpose of this parameter is to match the voice channel dB level to the input signal. A more negative setting produces a higher input gain (i.e., 7 produces the least input gain and -22 produces the highest input gain). If the In level is reduced (made more negative), the voice channel will be more sensitive to the input; this will cause the voice output at the remote device to sound louder.

The default value for this parameter is 0.

Level Out

This parameter speciÞes the local voice level out of the voice port. A more positive setting produces a higher volume (i.e., 7 produces the highest volume, -22 the lowest). The default value for this parameter is -4.

Long Dial Preﬁx

This parameter speciÞes a character or number 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., telephone or fax machine) dials a long-form number, the number must be preceded by the Long Dial PreÞx. Valid values are the digits 0-9 and the characters * (asterisk) and # (pound sign). The default value for this parameter is * (asterisk).

Num Digits Delete

This speciÞes the number of leading dial digits that will be deleted before a dial string is forwarded. This parameter is primarily used to delete leading digits that may be inserted by an attached PBX. For example, assume the user of attached equipment dials 1234 and the attached PBX inserts the number 9 as a preÞx to the dial string. If Num Digits Delete is set to 1, the SmartSwitch 1800 will remove the 9 before forwarding the dialed digits 1234. The default value for this parameter is 0.

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.
