MSS
Mass storage system
MSSNET
Mass storage/network control
MT
Management terminal
MTDM
Modular trunk data module
MTP
Maintenance tape processor
MTT
Multitasking terminal
multiappearance voice terminal
A terminal equipped with several call-appearance buttons for the same extension, allowing the user to
handle more than one call on that same extension at the same time.
Multicarrier cabinet
A structure that holds one to five carriers. See also
single-carrier cabinet
.
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.
N x DS0
N x DS0, equivalently referred to as N x 64 kbps, is an emerging standard for wideband calls separate
from H0, H11, and H12 ISDN channels. The emerging N x DS0 ISDN multirate circuit mode bearer
service will provide circuit-switched calls with data-rate multiples of 64 kbps up to 1536 kbps on a T1
facility or up to 1920 kbps on an E1 facility. In the switch, N x DS0 channels will range up to 1984
kbps using NFAS E1 interfaces.
