Quick Set-Up
2-4 Verilink NCC 2130 User Manual
4. Cisco™ routers are known to wrap the transmit clock signal
provided by the DSU back toward the DSU on the optional
third clock pair, Terminal Timing. Whenever the DTE offers
this feature, it should be used, since the clock on the TT pair
will be perfectly in phase with the Transmit Data provided by
the DTE. Use the “C” command and choose “3” for Terminal
Timing.
5. There are no more changes required to the default IDCSU
configuration to configure this example. Use the “X” command
to return to the NCC 2130 Main Menu.
The T1 circuit and DTE should now be connected.
When the router cable is connected to the IDCSU, the EQPT LED
stops blinking and is lit steady green.
Within 15 seconds of connecting the T1 circuit, the NET LED on the
NCC 2130 should change from red to green. If it does not, the
Diagnostics Menu can be used for troubleshooting. See
Chapter 5
for more information on diagnostics.
When the IDCSU has been connected to the T1 circuit for at least
fifteen minutes, meaningful performance statistics will be available
under the Performance Menu. See
Chapter 4 for more details.
The configuration of the NCC 2130 is covered in detail in Chapter 3
of this manual.
