POTS line test
The POTS units SUBH<X>, SUPC<X>, and SUPM<X> contain a line test functionality which can be configured via the UCST, or the FOXCST, respectively:
Specify a scheduled («Cyclic») line test for a SUBH<X> unit
Specify a line test for the SUPC<X> or SUPM<X> unit
Select the available line test measurements («Criteria») for the unit
UCST or FOXCST then allow the following:
Retrieve the results of the most recently executed line test («Get») and view them («Details»)
Execute a line test immediately («Test»)
These last two functions can also be performed via the northbound CLI interface for POTS line tests. The available commands allow retrieving the measurement values of the most recent line test for a particular SUBH<X>, SUPC<X>, and SUPM<X> port, or execute an immediate line test on a SUBH<X>, SUPC<X>, and SUPM<X> unit with the configured set of measurement types with subsequent automatic retrieval of the resulting measurement values.
The CLI syntax allows opening a communication channel via the FOXMAN-UN core to the NE containing the SUBH<X>, SUPC<X>, or SUPM<X> unit.

Please note: 
The POTS line test interface does not allow changing the line test configuration. This can only be done via the UCST or via the FOXCST, respectively.
