The default for all testing options is YES .
Send/Receive Inband Loop Cod
This option allows the CSU to control loopbacks with inband loop-up and
loop-down codes. If this option is disabled, the CSU does not respond to
inband loopback codes, nor will it send inband loopback codes.
Send Test Signal
This option allows the CSU to apply the desired test signal to the circuit.
If this option is disabled, the CSU does not apply test signals when
commanded by an operator.
Framed Test Signal
This option allows the CSU to apply framed test signals to the circuit. If
this option is set to
NO (disabled), the CSU applies only unframed test
signals.
When the CSU is used with DIUs, it interfaces with them through one or
two of the three data buses on the Access System shelf backplane.
Press to see the available choices. If the CSU is used with:
■
no DIUs, select NONE (the default).
■
DIUs in applications without drop-and-insert, assign data bus A , B ,
or C , whichever is available.
WARNING
If the TIU 2850 or TIU 1850 is installed in the shelf, do not select C,
because C is dedicated to providing timing from the TIU to the shelf
If the TAC is used with DIUs for drop-and-insert operation, selec
either D&I NET or D&I EQ (depending on the desired direction for this
operating mode). If D&I NET is chosen, databus A is assigned. If D&I
EQP is chosen, data bus B is assigned.
