Lucent Technologies 8403 manual

access these features by pressing Feature and then an entry number (1 through 9, 0, or the * or

#key). The directory has a surface that you can write or type on so that you can write or type the features assigned to each Feature Directory position (F1 through F9, F*, F0, or F#).

group list One of the four types of Abbreviated Dialing lists; programmable by the controller of the list or the system manager. Contains telephone numbers useful to members of a specific group, and stores each of those numbers as a 2-digit list item.

handset The handheld part of the voice terminal which you pick up, talk into, and listen from. Also known as the receiver.

off-hookWhen the handset is removed from the cradle (for example, when you lift the handset to place or answer a call) or when the speakerphone is turned on.

on-hookWhen the handset is left on the cradle or when the speakerphone is turned off.

party A person who places or answers a call.

personal list One of the four types of Abbreviated Dialing lists; programmable by the system manager or by you, the user. Contains telephone numbers of your choice, and stores each of them as a single-digit list item.

personal list item One of the 10 available slots on an Abbreviated Dialing personal list. The first nine personal list items are given digits 1 to 9, with 0 for the tenth item.

pickup group A group of up to 25 voice terminal users who can answer calls for each other through the Call Pickup feature. Group members are determined by the system manager and are usually located in the same work area or perform similar job functions.

priority call An important or urgent call which sends a special 3-burst ring.

program/reprogram To use your dial pad to assign a telephone number to an AD entry on y our Feature Directory or to a personal list item for Abbreviated Dialing.

retrieve To collect telephone messages with the Message or Voice Message Retrieval features. (Also, with Call Park, to resume a call from an extension other than the one where the call was first placed or received.)

ringer The device that produces the electronic ringing sound in your voice terminal.

stored number A telephone number which has been programmed and stored as a

1-, 2-, or 3-digit list item for use with Abbreviated Dialing. It can be a complete or partial telephone number, an extension number, or a feature or trunk code. Once programmed, a number can be accessed by first dialing the list, then the list item digit(s) under which it is stored. (Alternatively, if Abbreviated Dialing is on your Feature Directory, a number can be accessed by simply pressing Feature , and then dialing the appropriate entry number.)

8403 specifications

Lucent Technologies 8403 is a significant telecommunications switch that was primarily utilized in the late 1990s and early 2000s. It played a crucial role in the evolution of telecommunication systems, reflecting the rapid advancements in technology during that period. The 8403, part of the Lucent 8400 series, was known for integrating various features and capabilities that were vital for modern telecommunication networks.

One of the standout features of the Lucent 8403 was its advanced switching technology. Utilizing time division switching and digital signal processing, the device was capable of handling a large volume of calls simultaneously while maintaining high-quality voice transmission. This technology enabled efficient routing of calls and minimized the risk of dropped connections, which was a concern in earlier analog systems.

Another significant characteristic of the Lucent 8403 was its support for a wide range of telecommunications protocols. The switch was designed to facilitate both traditional telephone services and emerging digital services, including ISDN and Frame Relay. By accommodating both circuit-switched and packet-switched networks, the 8403 provided flexibility that major telecommunication providers demanded during that transition period.

The 8403 also featured enhanced signaling options, such as Common Channel Signaling System No. 7 (CCSS7), which allowed for improved call setup, control, and management. This feature significantly reduced the time it took to establish a call, thereby improving overall network efficiency.

Scalability was another key characteristic of the Lucent 8403. As telecommunication needs grew, service providers could expand their systems by integrating additional hardware and modules without requiring a complete overhaul of the existing infrastructure. This adaptability was crucial as demand for services fluctuated and as new technologies emerged.

Moreover, the switch was designed with reliability and redundancy features in mind. Its architecture included failover mechanisms that ensured continued operation even in the event of hardware failures. This reliability was essential for operators that required uninterrupted service delivery.

Lastly, the user-friendly interface of the Lucent 8403 provided simplified management and monitoring capabilities. System administrators could easily access performance metrics, troubleshoot issues, and manage configurations, facilitating more efficient maintenance and operations.

In conclusion, the Lucent Technologies 8403 played a transformative role in telecommunications infrastructure during its era. Its blend of advanced switching technology, protocol support, scalability, reliability, and user-friendly management tools made it a foundational component in the evolution of modern telecom networks. As a result, it served as a significant stepping stone toward the complex, integrated systems we see today.
