MCPC Digital Audio Receiver

ICP's new DCR-981 DigiCeiver® is the only Single Channel Per Carrier (SCPC) audio receiver that can also be utilized in a Multi Channel Per Carrier (MCPC) mode. Specifically designed for expanding existing SCPC networks, the DCR-981 is compatible with other manufacturers' networks. Its unique capability for MCPC mode, makes meeting future network demands for MCPC operation possible without changing receivers.

Introduction
The Model DCR-981 DigiCeiver® is an economical, all digital audio receiver intended for use in satellite based broadcast systems. Its many applications include radio program distribution to network affiliates and music distribution for corporate and retail applications. It is intended for use in many existing SCPC audio networks for network expansion and for new SCPC audio networks. It can also be used to expand ICP MCPC audio networks operating with or without our store and forward capability or expand SCPC networks to MCPC operation without changing receivers. The Model DCR-981 utilizes state-of-the-art digital technology, which allows a wide degree of flexibility to the user through the in-band network configuration and control capability.
The DCR-981 is an Single Channel Per Carrier (SCPC) receiver with a ISOMPEG Layer 2 decoder providing two audio outputs, four relay closures, and one ancillary data stream up to 19.2 kbps. The MPEG decoder is capable of delivering either one stereo or two mono outputs from a non-multiplexed digital source. It provides BPSK or QPSK operation at data rates of 64 kilobits per second (kbps) up to 384 kbps. Network control and configuration commands are multiplexed into the ancillary data channel along with relay closure information and user data, as part of the transmitted signal. This allows convenient control of all network receivers from the head-end.
A high performance sequential Forward Error Correction (FEC) decoder provides outstanding bit error rate (BER) performance. A Viterbi FEC decoder is also available. The DCR-981 is fully compatible with existing BPSK and QPSK, rate 12 coded digital signals currently transmitted by many service providers. Open network standards are followed for differential encoding, scrambling, forward error correction and signal spectral shaping to allow use in many existing open networks.
The ICP Network Control System (NCS) provides a greater degree of flexibility for network configuration but is not required for SCPC operation. When used, the NCS can configure Center Frequency, Carrier ID, Mode of Operation, Data Rate, Sweep Limit, and Error Rate Test Length from the head end or through the rear panel Remote connector on the receiver. They can also be entered locally through the front panel controls and display.
The DCR-981 is available in a desk top chassis design or with an optional rack mount. The desktop chassis measures 12"W x 8"L x 3"H and weighs less than 5.5 lbs (2.5 Kg)
An internal, universal input, switching power supply provides operation from 90 VAC to 260 VAC, 47 Hz to 63 Hz.
