4. Configuration
•There are only parameters for the a/b-interfaces. Thus there is only a need for a configuration, if the a/b-interfaces are available (NT+2ab mode and Pairgain mode; see chapter 2). The configuration remains stored, even after a power failure.
•The configuration is done by means of an analog telephone set equipped with tone dialing, having both ∗ and # keys.
Remark:
In normal use SANTIS-ab recognizes both pulse and tone dialing.
•If the NT+2ab mode is selected, all the configuration commands can be set from both the a/b-interfaces without any restrictions.
