Alcatel-Lucent 3EH76027AEJC – OmniPCX Enterprise IP Communication Server

The Alcatel-Lucent 3EH76027AEJC is a powerful call processing and communication server within the OmniPCX Enterprise product family, designed to serve medium to large enterprises with advanced voice, video, and collaboration capabilities. This server is the core component of the IP-PBX system, providing call control, signaling, media processing, and interworking with legacy telephony networks. It is built on a high-availability architecture with redundant processors, power supplies, and hot-swappable components, ensuring 99.999% availability. The 3EH76027AEJC supports up to 30,000 users in a distributed configuration and can be clustered with other servers for geographic resilience.

Hardware specifications include an Intel Xeon multi-core processor with 16 GB RAM and 500 GB storage, running a hardened Linux operating system. The server provides 4 Ethernet ports (10/100/1000) for LAN and WAN connectivity, and multiple expansion slots for TDM interfaces (E1/T1, BRI, PRI) via gateway modules. It supports up to 2,000 concurrent VoIP calls using G.711, G.729, and wideband codecs, with advanced DSP resources for conference bridges, transcoding, and DTMF detection. The server includes integrated Session Border Controller (SBC) functionality for secure SIP trunking and NAT traversal. Power consumption is 300 W typical, with optional redundant hot-swap power supplies.

The OmniPCX Enterprise software suite provides comprehensive unified communications features, including presence, instant messaging, audio/video conferencing, and mobility (fixed-mobile convergence). It supports open standards SIP, H.323, and MGCP, enabling interoperability with third-party endpoints and cloud services. The system includes a rich API for integration with CRM and ERP applications, and a web-based administration console for easy management. The server also includes built-in voice mail, auto-attendant, and call recording capabilities, with storage options via NFS or SAN.

Installation of the 3EH76027AEJC involves mounting the server in a standard 19-inch rack (2U height), connecting network and power cables, and configuring the IP addresses. The initial setup is performed via a serial console or web wizard, where the administrator defines the system parameters, user directories, and trunk configurations. The server supports automatic provisioning of IP phones using DHCP and TFTP, simplifying large deployments. Integration with legacy PBX systems is achieved through the gateway modules, with configuration of signaling protocols (ISDN, SS7, CAS).

Maintenance of the OmniPCX server includes regular software updates, monitoring of system logs, and health checks using the integrated diagnostics suite. The server provides SNMP traps and syslog forwarding to external management systems. Critical components such as the hard drives are configured in RAID 1 for redundancy. The internal battery for the real-time clock should be replaced every 5 years. Backups of the configuration database should be performed regularly and stored offsite. In case of hardware failure, the server can be replaced, and the configuration can be restored from backup, minimizing downtime.

Typical applications of the Alcatel-Lucent OmniPCX Enterprise include corporate headquarters, multi-site enterprises, call centers, and government institutions. Its scalability and feature richness make it a preferred choice for organizations with complex communication needs. The server's reliability and support for hybrid telephony (TDM/IP) allow gradual migration to all-IP solutions. The 3EH76027AEJC continues to be a cornerstone of Alcatel-Lucent's enterprise portfolio, providing the communication backbone for thousands of businesses worldwide, enabling efficient collaboration and superior customer service.
