Synchronous Network
The synchronization of transmission systems with synchronous payloads to a master (network)
clock that can be traced to a reference clock.
Synchronous Optical Network (SONET)
The North American standard for the rates and formats that defines optical signals and their
constituents.
Synchronous Payload
Payloads that can be derived from a network transmission signal by removing integral numbers
of bits from every frame. Therefore, no variable bit-stuffing rate adjustments are required to fit
the payload in the transmission signal.
Synchronous Payload Envelope (SPE)
The combined payload and path overhead of an STS-1 or STS-3c signal.
SYSCTL
System Controller (circuit pack)
SYSCTL - System Controller
The system controller circuit pack that provides overall administrative control of the terminal.
System View
A graphical depiction of the entire Network Element. Selectable objects in this view are the
bays and shelves.

T
T1
A carrier system that transmits at the rate of 1.544 Mb/s (a DS1 signal).
T1X1 and T1M1
The ANSI committees responsible for telecommunications standards
TA
Telcordia Technologies Technical Advisory
Target Identifier (TID)
A provisionable parameter that is used to identify a particular Network Element within a
network. It is a character string of up to 20 characters where the characters are letters, digits, or
hyphens (-).
