STP
See "signaling transfer point" (p. GL-25)
straight-tip connector (ST)
Fiber optic connector that uses a bayonet-style coupling rather than a screw-on coupling.
STS, STS-n
See "synchronous transport signal-n" (p. GL-28)
Sub-Network Connection Protocol (SNCP)
An SDH version of UPSR. See SDH and UPSR.
SW generic
See "software generic" (p. GL-26)
Synchronous Digital Hierarchy (SDH)
A family of digital transmission rates used outside of the U.S. and Japan from 51.84 Mb/s to 40
Gb/s that allows the interconnection of transmission products around the world.
SDH is the standard technology for synchronous data transmission on optical media. It is the
international equivalent of Synchronous Optical Network (SONET). Both SDH and SONET
technologies provide faster and less costly network interconnection than traditional
Plesiochronous Digital Hierarchy (PDH) equipment.
Synchronous Optical Network (SONET)
A North-American standard developed by Telecordia and adapted by ANSI for the optical
long-distance networks.
SONET is the interface standard for synchronous optical-fiber transmission, applicable to the
physical layer of the OSI reference model. SONET has a basic bit rate of 51.840 mB/s, called
OC-1, that is used to define higher rates (OC-3, OC-12, OC-48, and so on) carried as a channel on
an optical fiber.
synchronous signal
A data signal that is sent along with a clock signal.
synchronous transport signal-n (STS, STS-n)
The basic logical building block signal with a rate of 51.840 Mb/s for an STS-1 signal and a rate
of n times 51.840 Mb/s for an STS-n signal (where n is a numeric).

T tap
The entry point into a system module.
target identifier (TID)
A provisionable parameter used to identify an NE within a TL1 command.
TCA
