3. The default value for the density enforcement selection is not
correct for a B8ZS T1. Use the Z command, select “1” and press
E
NTER to change it to NONE. B8ZS was developed to eliminate
the need for density enforcement.
NOTE: For the remainder of this chapter you will not be instructed
to press E NTER each time. Generally, the E NTER key is used
after each command or value entry.
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 in order to configure this example. Use the X
command to return to the SCC 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
front of the SCC 2130 should change from red to green. If it does
not, the Diagnostics Menu may be used for troubleshooting, see
Chapter 5 for more information on diagnostics.
Once 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 SCC 2130 is covered in detail in Table 3-4
located in Chapter 3 of this manual.
Resetting the
STAT LED
The STAT LED normally will remain red for up to fifteen minutes
after all alarm conditions have cleared. A procedure may be used
to force the STAT LED to assume it’s typical condition, off. Follow
these steps:

Performance Menu.
2. Use the R command to reset the registers (all information
stored in the ESF registers for the preceeding 24 hours is
cleared).
3. Use the X command to return to the Main Menu.
4. Use the D command to select the Diagnostics Menu.
