DCS Compact II General Description C h a p t e r 1 . S y s t e m O v e r v i e w1-51.3 TechnologySwitchingSystem switching is accomplished by means of a custom IC "engine" thatprovides 256 switchable digital channels. The engine is controlled by its own16–bit Motorola MC 68000 microprocessor and switching control program.Each of the 256 digital channels is automatically assigned to carry voice or dataas required by system operation in a PCM format.In addition to the 256 channels mentioned above, the systems also utilize DigitalSignal Processors (DSPs). Each DSP may be configured by the switching controlprogram as a DTMF sender, a DTMF receiver or as a C.O. tone detector on aper–call basis. Each engine chip contains 4 DSP channels.Four additional DSPs are added when a MISC card is installed. This means thatthe system contains a total of 8 DSP channels when fully expanded. The DSPchannels are fully shared throughout the system as a common resource.MemoryThe systems operate using stored program control. This program is stored inEPROM chips. All specific customer data is stored in random access memory(RAM) which is protected against the loss of AC power to the system by an on–board battery backup system.MicroprocessorsDCS Compact II uses distributed processing. The primary processor of thesystem is a 16–bit Motorola MC68000 operating at a clock speed of 16 MHz.Secondary processing is in the some special cards like as BRI and also done inthe keysets. The digital keyset uses a Hitachi H8 processor for datacommunication within the DCS Compact II.
