RFL NCM RFL Electronics Inc. November 6, 2007 21 (973) 334-3100 SYSTEM OVERVIEW The Network Communications Module (NCM) is an Asynchronous Data Module designed for RFL IMUX 2000 T1 and E1 Multiplexers. The NCM provides one DCE Half/Full-Duplex channel between an unlimited number of locations using a single 64 kbps DS0 tim e slot.
RFL NCM RFL Electronics Inc. November 6, 2007 22 (973) 334-3100 NCM BACKPLANE AND POWER CONNECTIONS The NCM occupies a single slot in the multiplexer chassis and conforms to the RFL IMUX 2000 back plane signal format. All T1 and E1 signals, and control signals passing through the back plane, interface with the cross point Lattice device (U6).
RFL NCM RFL Electronics Inc. November 6, 2007 23 (973) 334-3100 1. SCB MODULE The SCB circuit is used to generate the read, write, and address data necessary to transfer control and status data to and from the SCB bus. The SCB a ddress is configured externally via SW1 and is selectable between 1 and 36.
RFL NCM RFL Electronics Inc. November 6, 2007 24 (973) 334-3100 In the Broadcast Mode of operation, all nodes receive the same data regardless of who is transmitting. The broadcasting applies to both ports of a two-port I/O. The Master Mode of operation designates a particular NCM at a node, as the master.
RFL NCM RFL Electronics Inc. November 6, 2007 25 (973) 334-3100 UART TRANSMIT SECTION The UART transmitters are programm ed for the appropriate baud, number of data bits, and whether or not parity is to be enabled for the output data to be transmitted.
RFL NCM RFL Electronics Inc. November 6, 2007 26 (973) 334-3100 6. T1 RECEIVE MODULE The T1 receive module clocks in the receive data at the proper time slot on the negative edge of the T1 clock, and latches it one clock following the time slot. The data is decoded as being either data or idle/address frame, and as being low or high frame.
RFL NCM RFL Electronics Inc. November 6, 2007 27 (973) 334-3100 TESTING After the NCM module has been configured and installed, it should be tested for proper operation before it is put into service. At present, the only test necessary to verify NCM performance is the loop test in NMS mode.
