H Select DS1 or DS3 to transmit a tributary rate signal.
NOTE. The CTS 710 can transmit only one signal rate at a time. The
CTS 710 can transmit either a SONET signal or a tributary signal,
but not both at the same time.
Independent Transmit and Receive Settings
Generally, you can set the transmit and receive settings independent-
ly. For example, you can receive an electrical signal at the STS-1
rate while simultaneously transmitting an optical signal at the DS1
rate.
However, when working with tributary and DSn signals, the transmit
and receive parameters are not completely independent. You cannot
transmit a DS1 signal and receive a DS3 signal. When working with
tributary signals, you must set the mapping for transmit and receive
to the same value or to Bulk Fill No Mapping. For example, you
can transmit a DS1 signal and receive an OC-12 signal, but you must
set the mapping of the received signal to either Bulk Fill No
Mapping or VT1.5; it cannot be set to DS3.
Coupling Transmit and Receive Settings
If your application requires that the transmit settings and receive
settings be identical, you can save time by coupling them together.
