SPCS
Stored Program Controlled Switch. A digital switch that supports call control, routing, and supplementary services provision under software control. All ISDN switches are SPCSs.
spoofing
Spoofing reduces the required bandwidth by having devices, such as bridges or routers, answer for the remote devices. This causes the remote LAN to ap- pear as if it is still connected to the LAN device even though it is not. The spoofing saves the WAN bandwidth, because no packet is ever sent out on the WAN.
synchronous
(1)The condition occurring when two events happen in a specific time rela- tionship with each other, both under control of a master clock; (2) A method of data transmission requiring the transmission of timing pulses to keep the sender and receiver synchronized in their communication used to send blocks of information. Synchronous data transmission is used in high speed data cir- cuits because there is less overhead than asynchronous transmission of char- acters which contain two extra bits per character to effect timing.
