after each command or value entry.
4. Cisco™ routers wrap the transmit clock signal provided by the

configuration for this example. Use the XXXX command to return

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
TAC 2130-T 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, performance statistics will be available under the
Performance Menu. See
Chapter 4 for more details.
The configuration of the TAC 2130-T is covered in detail in Chapter
3 of this manual.
