Glossary
Definition
Term
Rate of SG. Rate is sum of overhead, orderwire, and traffic rates
Composite rate
that make up SG.
Data that is entered in non-volatile memory (NVM) by operator
Configuration data
to make TD-1337(V)/G operate in designated network.
Routine performed by operator to enter configuration data in NVM
Configuration routine
or routine performed to place TD-1337(V)/G in another mode of
operation.
Methods by which TD-1337(V)/G's can be functionally interconnected
Connectivity
to provide various satellite communication networks.
Control telemetry is part of the overhead in the supergroup (SG).
Control Telemetry
Control telemetry is used to transmit/receive configuration data,
orderwire mode data, and slave timing data between TD-
1337( V)/G's.
Each TD-1337(V)/G model has one conditioned diphase input/output
Dedicated user
at a 16 or 32 kb/s rate. The user connected to this input/output
is called the dedicated user.
Section(s) in TD-1337(V)/G that receives SG(s) from remote TD-
Demultiplexer (demux)
1337(V)/G(s). Each demux generates strobe signals, at the proper
times, to enable decombing (separating) the incoming SG into its
composite parts.
"DI" in a message display is abbreviation for "conditioned
Dl
diphase". Conditioned diphase is one of signal formats that can
be processed by TD-1337(V)/G.
