Step 2 Check the state field for the BITS port being used. If it is down, check the cable for damage.
Step 3 Check the BITS port LED. If it is not on, check the interface mode type. The mode type is either T1
or E1. T1 is the default mode. Use the network-clock-select command to change the BITS interface
mode type.
For detailed interface configuration information on network clocking, refer to the “Initially Configuring
the ATM Switch Router,” and Chapter 18, “Configuring Circuit Emulation Services” chapter in the ATM
Switch Router Software Configuration Guide.
