Attaching Adjunct Equipment

If you are installing a speakerphone (Lucent Technologies models S101A, S201A, or QUORUM® CS201A), a headset adapter (Lucent Technologies model 500A1), or other adjunct that may be offered, follow these steps to connect the adjunct equipment to your voice terminal.

The adjunct requires auxiliary power from either a local, individual power supply or a closet supply serving multiple phones. Refer to the adjunct's installation documentation for its power requirements.

1.Place the voice terminal face down on a flat surface.

2.Snap the adjunct cord into the Adjunct jack until you hear a click. (This jack is

labeled , except on the 8411, where it is labeled “ADJUNCT.”) See Figure 1 for the location of the Adjunct jack on the 8403, 8405, and 8410 voice terminals. See Figure 2 for the location of the Adjunct jack on the 8411 voice terminal. See Figure 4 for the location of the jack on the 8434DX voice terminals.

3.Refer to the “Desktop Installation” section for instructions on routing the adjunct cord through the channel.

4.Connect the free end of the adjunct cord to your speakerphone, headset adapter, or other adjunct.

5.Then, do one of the following:

—If auxiliary adjunct power is provided by a bulk closet supply, connect the line cord from the voice terminal to the wall jack.

—If a local, individual auxiliary power supply is being used, refer to Figure 9 for information about how to connect the telephone to the wall jack.

NOTE: If the voice terminal is being used with the 4-wire

7400B Plus or 2-wire 8400B Plus data module, the telephone line cord connects to the Phone jack on the 7400B Plus or 8400B Plus instead of to the wall jack. The Line connector on the 7400B Plus or 8400B Plus is then connected to the wall jack. Refer to the 7400B Plus Data Module User’s Guide or 8400B Plus Data Module User’s Guide for further information on using either of these data modules.

NOTE: The 7400B Plus or 8400B Plus data module cannot be used with the 8411 when the voice terminal is optioned for a second telephone number for the Analog Adjunct jack. Refer to the 7400B Plus Data Module User’s Guide or 8400B Plus Data Module User’s Guide for further information on using either of these data modules.

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.
