California Microwave Announces SMPTE 310M Interface Option for the EFData SDM-2020 Satellite Modem.

SUNNYVALE, Calif.--(BUSINESS WIRE)--April 19, 1999--

California Microwave, Inc. (Nasdaq/NMS:CMIC) announced today a major expansion of its EFData SDM-2020 satellite modem product line to include the new SMPTE 310M interface.

Developed as a recognized standard by the Society of Motion Pictures and Television Engineers (SMPTE), the SMPTE 310M interface is a preferred electrical connection standard for delivering the Advanced Television Systems Committee (ATSC) digital video transport streams at 19.39 Mbps.

The EFData SDM-2020 modem has been adopted by two major US television broadcast networks for their new digital program delivery. With the addition of the SMPTE 310M interface, the EFData SDM-2020 Modulator and SDM-2020 Demodulator now will connect directly to industry standard ATSC encoders, multiplexers and switches as well as to fiber and microwave radio modulators and broadcast transmitters.

California Microwave is featuring the new EFData SDM-2020 at the Las Vegas Convention Center, Booth No. L21142, during the National Association of Broadcasters' Convention, April 19-22, 1999.

Interface Slides into Modem, No Disassembly Required

Like other connection options for the SDM-2020, the SMPTE 310M interface simply slides into the rear of the modem, eliminating chassis disassembly and removal of the modem from the rack. The SMPTE 310 Interface also operates with the SDM-2020 in either standard QPSK or optional 8PSK modes; both are ATSC and Digital Video Broadcast (DVB) compliant. The SMPTE 310M interface can be ordered initially with the SDM-2020, or later as a spare for field swap out.

California Microwave is taking orders for the SDM-2020 modulators and demodulators with typical deliveries 30 days after receipt of order.
