INSTALLING YOUR VOICE TERMINAL

IMPORTANT: For a fuller description of installing the 8400-Series voice terminals and procedures on administering these sets and programming such options as enabling/disabling the speakerphone or one-way speaker, enabling/disabling the Mute function, selecting ringing preference, or selecting handset and speaker volume control, see the 8400-Series Voice Terminals Instructions for Installation, Switch Administration, and Programming the Options, 555-015-725. (This document can be ordered from the Lucent Technologies BCS Publications Center at 1 800 457-1235.)

Distance Limitations

In 4-wire operation, the voice terminal must be within 5,000 feet of the PBX using 22-gauge or 24-gauge wire, and within 4,000 feet of the PBX using

26-gauge wire.

In 2-wire operation, the voice terminal must be within 5,500 feet of the PBX using 22-gauge wire, within 3,500 feet of the PBX using 24-gauge wire, and within 2,200 feet of the PBX using 26-gauge wire.

Auxiliary Power

In both a 4-wire or 2-wire configuration, most 8400-Series voice terminals are phantom powered from the PBX. However, you will need auxiliary power in the following instances:

If you are using an 8411 or 8434DX voice terminal (These sets require auxiliary power.)

If you have an 801A Expansion Module (used ONLY with the 8434DX voice terminal connected to a DEFINITY® Communications System G3V3.3 or later switch)

If there is an attached adjunct equipment, such as an S201A Speakerphone

The following power supplies can be used with the 8400-Series voice terminals:

Stand-alone 1151A1 Power Supply (PEC: 2404-010;

Comcode: 107785693) and 1151A2 Power Supply with Battery Holdover

(PEC: 2404-012; Comcode: 107785339)

Stand-alone MSP-1 (PEC: 2404-010; Comcode: 406743419)

1145A Bulk Power Supply (PEC: 2404-011;

Comcode: 106448939)

Battery for the 1145A (2.5 amp per hour battery) (Comcode: 106448921)

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.
