FXS Ports 6-5
PATTRN
The Pattern field selects an outgoing test pattern for the current port. The test pattern is
generated by the system and sent to the selected port. You can select a different pattern for
each port. The none option disables the test pattern. The D-mW (Digital milliwatt) option
sends a 1 kHz tone at 0.0 dBm. The setting of the Rx TLP setting affects the D-mW signal
level.
6.3.2 Test Screen
The Test option facilitates testing and maintenance by allowing you to monitor and set the
status of the analog interface leads, and to monitor or set the value of the A, B, C, and D
signaling bits of all FXS circuits on that port. In cross-connect systems, the test option also
allows you to apply test patterns and tones towards the user and network sides of the system.
