1. Safety Instructions
•Place the SANTIS-ab near a 230 V outlet.
•Do not open the case.
•Clean the case only with dry or moist cloth.
Never immerse into water.
•If the SANTIS-ab is damaged, inform immediately your
network provider.

2. Operating Modes
The connection to the public telephone network as well as the
selection of one of the following three operating modes must be
done by an authorized person, e.g. telecom staff:
1. NT+2ab S- and a/b-interfaces available
2. NTBA Only S-interface available
3. Pairgain Only a/b-interfaces available

3. Installation
•If both the green LEDs light steadily, the SANTIS-ab is ready
for operation (see figure on page 2).
The following installation-steps can be done by everyone.
•The SANTIS-ab can be wall-mounted or placed on the desk
(piling of more units is also possible). In case of wall
mounting, drill the holes into the wall according to the
enclosed drawing, insert dowels with wood screws and hang
on the SANTIS-ab.

•Connection of the terminal equipments:
The sockets for the analog equipments (e.g. telephones, gr.2/3
fax machines, modems) are designated with «a/b1» and
«a/b2», those for the ISDN terminal equipments with «S»
(e.g. ISDN-telephones, PC with ISDN-card, gr.4 fax
machines). See figure on page 2.

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.

9
If the configuration access (CA) is restricted (can be set and
changed by authorized persons, e.g. telecom staff), the
configuration for the a/b1-interface can only be done via the
a/b1-interface and vice versa for the a/b2-interface.
This mode is called NT+2ab/CA restr.
If the Pairgain mode is selected, the configuration access is
automatically restricted, i.e. the configuration for the a/b1-
interface can only be done via the a/b1-interface and vice
versa for the a/b2-interface.

10
The settings are executed as follows. See also flow chart on next
page.
1. Hook off and wait for dial tone
2. Dial ∗∗→The dial tone is switched off
3. Dial the command number and parameter value according to
the tables in chapter 5.
4. Dial #→If the parameter has been programmed
successfully, a permanent tone is switched on.
Otherwise a busy tone will be switched on.
5. Proceed with step 3. if necessary for setting other parameters
or hook on.
