Setting the Signal Level (MCT1 Only)
By default, the T1 transmit power level is 0.0 dB. Specify a decibel level from
-15 dB to 1.5 dB, according to the length of the cable or as determined by the
carrier. Refer to “Setting the Signal Level,” earlier in this chapter, for more
information.
Enabling or Disabling the International Bit (MCE1 Only)
By default, MCE1 does not use the international bit in E1 frames. Enable or
disable use of the International Bit for testing an MCE1 interface.
Running Port Tests
To run MCE1 or MCT1 port tests:
1. Set the test parameters in the Port Actions window.
Refer to the “Setting Port Test Parameters” section.
2. Click on Apply.
3. To start a test, click on the appropriate Send Command.
T
able 7-3 describes the BERT test commands you can send on any MCT1 or
MCE1 port. T
able 7-4 describes the loopback commands you can send on an
MCT1 port only.
Note: Port tests affect all logical lines associated with that port.
