Independent Receive and Transmit Settings
Generally, you can set the receive and transmit settings independent-
ly. For example, you can receive an electrical signal at the DS3 rate
while simultaneously transmitting an optical signal at the OC-3 rate.
However, when working with tributary 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 No Mapping. For example, you can transmit
a VT1.5 signal and receive an OC-12 signal, but you must set the
mapping of the received signal to either No Mapping or VT1.5; it
cannot be set to DS3.
Coupling Receive and Transmit Settings
If your application requires that the receive settings and transmit
settings be identical, you can save time by coupling them together.
After they are coupled, any change you make to a parameter on the
RECEIVE SETTINGS page will also be made to the corresponding
setting in the TRANSMIT SETTINGS page of the RECEIVE menu.
The inverse is also true.
To couple the receive and transmit settings together from the
RECEIVE SETTINGS page:

NOTE. When settings are coupled from the RECEIVE SETTINGS
page, the transmit parameters are changed to match the receive
parameters. Conversely, when settings are coupled from the
TRANSMIT SETTINGS page, the receive parameters are changed to
match the transmit parameters.
