    Theory of Operation The MERLIN II system architecture provides a digital SYSTEM network that supports voice and data communications. ARCHITECTURE The modular nature of the system makes the base configuration efficient and easy to expand. The control unit contains the memory for the system’s features, Input/Output (I/O) functions, and interface requirements.

  • Page 41 The Power Supply Module Power Supply Module. converts 117 VAC line voltage to the following outputs: +5 VDC, -5 VDC, and -48 VDC (tip/ring). The central processor complex Processor Module. consists of a main board and the Feature Module. The main board contains the 68000 microprocessor, RAM, a real-time clock, interrupt circuitry, and port interface to the modules through the I/O bus.
  • Page 42 If you use a 008 module in this slot, you must provide for outside lines using another module. The 408 module has a port processor to handle real- time intensive tasks such as ATL line protocol and central office rotary outpulsing. The port processor receives instructions from the main processor over the I/O bus.

    processor. The port processor directs Touch-Tone circuitry to output tones. The tones are placed on the TDM bus by the DSE through buffer circuitry. After a tip condition occurs at the remote end, a conversation may occur. The MERLIN II system receives analog signals from the ANALOG TO DIGITAL central office lines and analog modules.
  • Page 44 PCM uses PAM as its starting point but goes further. PCM digitizes the information and sends the 8-bit code via PAM. PCM digitizes the PAM information by comparing each PAM sample to a point on a chart. Each point has a distinct 8-digit binary code.

  • Page 46 Each module has a DSE to interface codecs or digital transceivers to the TDM bus. The actual digital switching occurs when the DSE is programmed by the system I/O bus to place (transmit) data or retrieve (receive) data on the TDM bus in specific time slots. This process also involves time slot interchanging so that an available slot in the TDM cycle can be filled with a talk (transmit) or listen (receive) slot.
