NETWORK INTERFACE MODULE (NetNIM)
SECTION 6 NETWORK INTERFACE MODULE (NetNIM)The NetNIM interfaces the Call Processor to the internal communication of the Switch. The NetNIM passes data communication via a 19200 baud full duplex channel on the
The Master Clock and Master Sync for the PCM busses are redundant in the NetNIM. A detection circuit monitors the two different sets and if Master
The Switch is allowed a Master and Slave NetNIM, enabled or disabled from operation on the data communication path. The master tells the slave when both of its clocks are off frequency and the slave clock is distributed, if the slave clocks are on frequency.
6.2 OPERATIONThe NetNIM may be redundant using a master and slave module. The master is placed in a card slot with the least significant bit equal to zero. The slave is placed in a card slot with the least significant bit equal to one. The NetNIM Master/Slave LED is ON for master and OFF for slave.
The card slot(s) used for the NetNIM has the backplane wired for this operation. Refer to Section 23 for further details.
