Glossary and Abbreviations 
GL-23  
Multifrequency Compelled (MFC) Release 2 (R2) signaling
A signal consisting of two frequency components, such that when a signal is transmitted from a 
switch, another signal acknowledging the transmitted signal is received by the switch. R2 
designates signaling used in the United States and in countries outside the United States.
multiplexer
A device used to combine a number of individual channels into a single common bit stream for 
transmission.
multiplexing
A process whereby a transmission facility is divided into two or more channels, either by splitting 
the frequency band into a number of narrower bands or by dividing the transmission channel into 
successive time slots. See also time-division multiplexing (TDM)
.
multirate
The new N x DS0 service (see N x DS0).
MWL
Message-waiting lamp
N
N+1
Method of determining redundant backup requirements. Example: if four rectifier modules are 
required for a DC-powered single-carrier cabinet, a fifth rectifier module is installed for backup.
NANP
North American Numbering Plan
narrowband
A circuit-switched call at a data rate up to and including 64 kbps.
native telephone support
A predefined telephone type exists in switch software, eliminating the need to alias the telephone 
(that is, manually map call appearances and feature buttons onto some other natively supported 
telephone type).
NAU
Network access unit
NCA/TSC
Noncall-associated/temporary-signaling connection
NCOSS
Network Control Operations Support Center
NEMA
National Electrical Manufacturer’s Association
NETCON
Network-control circuit pack
network-specific facility (NSF)
An information element in an ISDN-PRI message that specifies which public-network service is 
used. NSF applies only when Call-by-Call Service Selection is used to access a public-network 
service.

NID

NM
Network management
node
A switching or control point for a network. Nodes are either tandem (they receive signals and pass 
them on) or terminal (they originate or terminate a transmission path).
Nonfacility-associated signaling (NFAS)
A method that allows multiple T1 and/or E1 facilities to share a single D-channel to form an 
ISDN-PRI. If D-channel backup is not used, one facility is configured with a D-channel, and the 
other facilities that share the D-channel are configured without D-channels. If D-channel backup is 
used, two facilities are configured to have D-channels (one D-channel on each facility), and the 
other facilities that share the D-channels are configured without D-channels.

packet
A group of bits (including a message element, which is the data, and a control information element 
(IE), which is the header) used in packet switching and transmitted as a discrete unit. In each 
packet, the message element and control IE are arranged in a specified format. See also packet 
bus and packet switching.
packet bus
A wide-bandwidth bus that transmits packets.
packet switching
A data-transmission technique whereby user information is segmented and routed in discrete data 
envelopes called packets, each with its own appended control information, for routing, sequencing, 
and error checking. Packet switching allows a channel to be occupied only during the transmission 
of a packet. On completion of the transmission, the channel is made available for the transfer of 
other packets. See also BX.25
 and packet.
paging trunk
A telecommunications channel used to access an amplifier for loudspeaker paging.
party/extension active on call
A party is on the call if he or she is actually connected to the call (in active talk or in held state). An 
originator of a call is always a party on the call. Alerting parties, busy parties, and tones are not 
parties on the call.

the logical point where signaling is passed between two peer entities in a private network. QSIG 
signaling can provide feature transparency in a single-vendor or multi-vendor environment.
