Multi-Floor Voice Communication System Upgrade

Products Used：

PCM voice multiplexer (supports 4/8/16 voice channels)

Project Background:

To improve communication efficiency and modernization, a comprehensive hospital in Shandong launched a system-wide upgrade of its voice communication infrastructure across multiple aging buildings. The legacy analog wiring was outdated, unreliable, and prone to interference, resulting in delayed response times and maintenance difficulties.

Solution:

The hospital deployed compact PCM voice multiplexers, capable of aggregating 4/8/16 voice channels, and used a single-core optical fiber to transmit all voice data from multiple buildings to a centralized control room in the newly built medical technology complex. This streamlined the hospital's communication network and improved dispatch efficiency.

Application Scenarios:

Intercom and dispatch communication between medical staff

Voice link between nurse stations and central command

Emergency alert and fast-response ward communication system

Project Outcome:

The upgrade unified the hospital’s multi-floor voice communication structure, cutting cabling costs by approximately 40 percent. With stable transmission and millisecond-level response times, the system established a near-zero delay communication mechanism among staff, greatly enhancing operational efficiency and patient care.
