Lucent's MMCX Server now supports PC endpoints and the latest ITU standards.

Michelle Campanale

The latest release of Lucent's MMCX (Multimedia Communications Exchange) Server extends multiparty conferencing to mixed-media sessions on PCs, Unix workstations, or any standards-compliant device connected to a LAN or WAN. The MMCX Server can link with a PBX (i.e., a circuit-switched telephony network) for TCP/IP internetworking with phones and multimedia PCs.

Available since July, the second release of the server and client software now supports Intel-compatible PC endpoints running either Windows 95 or NT. Although it's a pricey package (starter kits begin at $36,650), MMCX Server now offers support for any kind of mixed media and handles mixed-media sessions the same way it handles conference calls. Also new to this version is support for H.323, the Internet/LAN ITU standard for voice and video data over IP. In addition, the MMCX Server now supports T.120-based data sharing (for shared applications and whiteboarding) and mobility, so users can access any MMCX endpoint by using a single log-in name.

By year's end, Lucent plans to add support for MASI (which allows the Definity PBX to act like a features server sitting on a LAN); H.320, an early ISDN standard that's circuit-switch-based for voice and video over 128-Kbps lines; and H.263 video capabilities.

I tested an early version of Lucent's newest MMCX Server release. After linking to a Definity PBX and a 24-B-channel ISDN Primary Rate Interface (PRI), I plugged the server into three Windows 95 machines. These three clients each contained 32 MB of memory, a Windows-compliant video-capture card, and a full-duplex sound card, in accordance with Lucent's specifications.

I initiated a conference call among the three client PCs on the LAN as well as a phone that was plugged into our PBX. Then, using Lucent's client-side user interface, it was easy to initiate the system's H.261-compression-based videoconferencing, share whiteboard and Word documents, and transfer and forward calls.

Based on a 166-MHz Pentium processor, MMCX Server comes with 48 MB of DRAM, a 2-GB SCSI-2 hard drive, a 1.44-MB floppy drive, and a WILDcard (WAN to LAN device card) that provides interfacing among LAN, Ethernet, and ATM network interface cards (NICs) and E1/T1 circuit-switched networks. IS managers who have an immediate need for a multimedia conferencing package should take a look at Lucent's MMCX Server. With no direct competition, it represents a robust solution that's easily integrated into existing PCLANs.

My approach to software engineering is far more pragmatic than it is theoretical--and no language better exemplifies this than C++.
