Network Parameter Control: Network Parameter Control is defined as the set of 
actions taken by the network to monitor and control traffic from the NNI. Its main 
purpose is to protect network resources from malicious as well as unintentional

NRZ
Non-Return to Zero: A binary encoding scheme in which ones and zeroes are 
represented by opposite and alternating high and low voltages and where there is 
no return to a zero (reference) voltage between encoded bits.NRZ is now used as 
an encryption scheme for getting data onto and off hard disk fast.It eliminates the 
need for clock pulses and yields up to 18.5 kilobytes per track and high read/write 
speeds.
NSAP 
Network Service Access Point: OSI generic standard for a network address
