Panasonic 1200N User Manual

Network Element Function: A function within an ATM entity that supports the 
ATM based network transport services, (e.g., multiplexing, cross-connection). 

A node that is directly connected to a particular node via a logical link. 

Network Element Layer: An abstraction of functions related specifically to the 
technology, vendor, and the network resources or network elements that provide 
basic communications services. 

Near End Crosstalk: Equipment that must concurrently receive on one wire pair and 
transmit on another wire pair in the same cable bundle must accommodate NEXT 
interference. NEXT is the portion of the transmitted signal that leaks into the 
receive pair. Since at this point on the link the transmitted signal is at maximum and 
the receive signal has been attenuated, it may be difficult to maintain an acceptable 
ACR with the received signal if the cable media allows large amounts of crosstalk 
leakage to occur. Foiled or shielded cables generally have less crosstalk than 
unshielded varieties. 

Network Interface Card: The attachment that connects a device to a network. The 
NIC, usually a PC expansion board, executes the code needed by the connected 
device to share a cable or some other media with other stations.

Narrowband Integrated Services Digital Network: Services include basic rate 
interface (2B+D or BRI) and primary rate interface (23B+D or PRI). Supports 
narrowband speeds at/or below 1.5 Mbps. 

Network Management Entity: The body of software in a switching system that 
provides the ability to manage the PNNI protocol. NM interacts with the PNNI 
protocol through the MIB. 

An ABR service parameter, Nrm is the maximum number of cells a source may 
send for each forward RM-cell.
