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.

4

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

5

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.

6

• 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.

7

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

keys.

set equipped with tone dialing, having both

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.

#

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/b1­interface can only be done via the a/b1-interface and vice
versa for the a/b2-interface.

All parameters having a default value are affected.

The default values are set in the factory and can be reseted by this
command.

Restrictions for NT+2ab/CA restr. and Pairgain:
A parameter reset via the a/b1-interface affects only a/b1­parameters and vice versa for a/b2. The MSNs can not be reseted.

Hot line means that a predefined number is dialed automatically
after hook off (e.g. baby-call, alarm-call). In order to switch the
hot line off, hook off and start immediately to dial the off­command.

0

*) First hooked off, first served

Emergency mode means failure of the mains. Then only one
terminal equipment can be operated at either the S- or one of both
the a/b-interfaces. The preferred interface can be selected by this
command.
If set to ‘1’, the emergency priority of all the S-bus terminal
equipments must be disabled.

Restrictions:
The switch is only available in the NT+2ab mode.
NT+2ab/CA restr.: Can only be set by authorized persons.
Pairgain: Automatically set to ‘1’ and can not be changed.

In order to have all the benefits of an ISDN the SANTIS-ab
should know the type of terminal equipment connected to both
the a/b-interfaces.

Restrictions for NT+2ab/CA restr. and Pairgain:
a/b1 via a/b1 only; a/b2 via a/b2 only.

at a/b2-interface

If you answer a phone call, you can hook on and the connection is
still available, if you hook off again within
3 minutes (the caller must not hook on). This feature is called
‘clear back time delay’ and can be suppressed by this command.

Restrictions for NT+2ab/CA restr. and Pairgain:
a/b1 via a/b1 only; a/b2 via a/b2 only.

17

PABX-Switch
Command-No / Meaning Parameter value Default

Some terminal equipments (e.g. modems) do not work correctly,
if metering pulses are sent. Thus it is possible to switch them off.

Restrictions for NT+2ab/CA restr. and Pairgain:
a/b1 via a/b1 only; a/b2 via a/b2 only.

The call waiting tone is a tone in the receiver signaling an incom­ing call during a call is already ongoing. This service is not
available at every network provider.
The incoming call can be answered by finishing the ongoing call
(hook on, SANTIS-ab rings, hook off).
The call waiting tone can be switched off, e.g. if a fax machine or
a modem is connected to the a/b-interfaces.

Restrictions for NT+2ab/CA restr. and Pairgain:
a/b1 via a/b1 only; a/b2 via a/b2 only.

In the ISDN world the number of the caller is submitted to the
called party.
CLIR means ‘Calling Line Identification Restriction’, i.e. the
caller number is not submitted.
Additionally the CLIR-service must be activated in the central
office by your network provider.

Restrictions for NT+2ab/CA restr. and Pairgain:
a/b1 via a/b1 only; a/b2 via a/b2 only.

Configuration Example 1:

Priorising a/b-interfaces during emergency mode

1. Hook off and wait for dial tone, then dial

2.

→ the dial tone is switched off

∗∗
210 1 #

3. When a permanent tone is switched on, hook on.

23

Configuration Example 2:

A fax machine gr.3 is connected to the a/b1-interface.
Thus the MSN and HLC are to be set:
MSN = 456, HLC = fax gr.2/3 for a/b1.

1. Hook off and wait for dial tone, then dial

2.

→ the dial tone is switched off

∗∗
111 456 #

3. When the permanent tone is switched on proceed to 4 and

dial

→ 1st MSN for a/b1

4.

221 2 #

5. When the permanent tone is switched on, hook on.

24

→ HLC for a/b1

Remarks:

• There is a time limitation for the programming. If one
sequence is not finished within 30 seconds, an internal
generated busy tone will be switched on.

• Check if the programming was successful with test calls

between two a/b-interfaces or from an ISDN-telephone set to
an analog one and vice versa.

25

6. Troubleshooting

1. Check the green LEDs on the top of the case: both must light
steadily.

• If the LED designated with ‘local feeding’ is off, check

the power cord.

• If the LED designated with ‘remote feeding’ is off and

remains off for some minutes
provider.

2. Check the correct connection of the terminal equipments to
the SANTIS-ab. Analog equipments must be connected to
a/b1 and a/b2, digital equipments to S.
