SSP
scaleable signal processor
station message desk interface (SMDI)
See simplified message desk interface (SMDI).
station message detail recording
See call detail recording (CDR).
subscriber
A Lucent INTUITY user who has been assigned the ability to access the INTUITY AUDIX Voice Mes-
saging system.
surge
A sudden rise and fall of voltage in an electrical circuit.
surge protector
A device that plugs into the telephone system and the commercial AC power outlet to protect the
telephone system from damaging high-voltage surges.
SW
Switch integration application identifer. See application identifer.
switch
An automatic telephone exchange that allows the transmission of calls to and from the public tele-
phone network. See also private branch exchange (PBX).
switched access
A connection made from one endpoint to another through switch port cards. This allows the end-
point (such as a terminal) to be used for several applications.
switch hook
The device at the top of most telephones that is depressed when the handset is resting in the cra-
dle (that is, when the telephone is
on hook ). This device is raised when the handset is picked up
(that is, when the telephone is
off hook ).
switch-hook flash
A signaling technique in which the signal is originated by momentarily depressing the switch
hook.
switch integration
Sharing of information between a messaging system and a switch to provide a seamless interface
to callers and system users. A fully integrated INTUITY AUDIX system, for example, answers each
incoming telephone call with information taken directly from the switch. Such information includes
the number being called and the circumstances under which the call was sent to it, for example,
covered from a busy or unanswered extension.
switch integration device (SID)
A combination of hardware and software that passes information from the switch to the Lucent
I
NTUITY system thus allowing it to share information with non-Lucent switches. The operation of a
SID is unique to the particular switch with which it interfaces.
switch network
Two or more interconnected switching systems.
synchronized mailbox
A mailbox that is paired with a corresponding mailbox in another domain and linked via software
that keeps track of changes to either mailbox. When the contents of one mailbox change, the soft-
ware replicates that change in the other mailbox.
