T-1 Line Tests
The DS1a and DS1b submenus provide the parameters that allow you to activate Local
Line Loop tests, Local Channel Loop tests, Bundle Loop tests, and Pattern Tests on T-1
lines A and B, respectively. The parameters are identical for both line submenus.
Note
: The Local Channel Loop and Bundle Loop are available only on units equipped
with two T-1 line interfaces.
The Local Line Loop test loops all the DS0 channels (01 through 24) on the DS1 line
towards the network. It is bidirectional for channels assigned to a DTE. It is not
bidirectional for cross-connected channels. To activate this test, follow these steps,
starting from the Diagnostic Mode submenu:
