Site Link
Troubleshooting the Site Link essentially consists of checking the correct operation of each
layer in the order starting with the physical layer.
The physical layer may be configured to be either E1 or X.21. The status bsl command
provides different information for the two interface types.
X.21 Interface
If the Site Link interface had been configured to use X.21 interface, the information
provided by the status bsl command is as follows:
SC) status bsl
