General Configuration Options

Clock Src: NET
Next NET Prt1 Int Prev
DSU/CSU Clock Source. Specifies the master clock source for the DSU/CSU. This selection synchronizes all internal
timing and external interface clocks. The clock rate(s) for the external timing interfaces are independent of the input rate
for the master clock. Failure of the clock specified by the Clock Source selection results in automatic fallback to internal
clock.
NET – Configures the network interface as the master clock source.
Prt1 – Configures Port 1 as the master clock source.
Int – Configures the internal clock as the master clock source.
Tst Timeout: Enab
Next Enab Disab Prev
Test Timeout. Specifies whether user-initiated loopback and pattern tests have durations that are specified by the
Tst Duration configuration option.
Enab – Loopback and pattern tests initiated on the DSU/CSU have specified durations.
Disab – Disables test timeout. The tests are terminated manually.
NOTE: For DSU/CSUs that are remotely managed through an inband data stream such as the FDL, the recommended
setting is Enab. If tests are inadvertently left in the active state, the Enab setting will allow the test to timeout
(terminate) after a specified time.
Tst Duration: 10
Next Up Down Save Prev
Test Duration. Specifies the duration (1 to 120 minutes) of user-initiated loopback and pattern tests. (The Tst Timeout
configuration option must be set to Enab.) Use the left or right arrow key to position the cursor on the digit you want to
change. Use the Function keys (Up or Down) to increment or decrement the digit.
Up – Increments the test duration.
Down – Decrements the test duration.
Save – Stores the test duration.
