Network Circuit Identifier. Specifies the transmission vendor’s circuit identifier for the
purpose of facilitating troubleshooting. The network circuit identifier is an ASCII text
string that may be up to 255 characters in length.
Edit – Allows you to edit and/or display the network circuit identifier using the generic
text string entry screen.
Clear – Allows you to clear the network circuit identifier. The network circuit identifier is
set to a null string.
General Configuration Options

Table C-3. General Configuration Options (1 of 2)

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 the data port as the master clock source. If you enable EDL if for the
data port and the DSU/CSU Clock Source is set to Prt1, the external device must
provide clocking of 8 kbps less than the expected data port rate. For example, if you
select 64 kbps, the external clock must supply a 56 kbps clock signal.
Int – Configures the internal clock as the master clock source.
TstTimout: 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 EDL or 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.
