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.

5
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

6
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.

7
•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.

8
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.

5. Table of Configuration Commands
Parameter-Reset
Command-No / Meaning Parameter value Default
010 reset of all
parameters to the
default value
1 ---
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/b1-
parameters and vice versa for a/b2. The MSNs can not be reseted.

13
Multiple Subscriber Number (MSN)
Command-No / Meaning Parameter value Default
111 1st MSN for a/b1 0 to 16 digits --- *)
121 2nd MSN for a/b1 0 to 16 digits 0000 0000
131 3rd MSN for a/b1 0 to 16 digits 0000 0000
112 1st MSN for a/b2 0 to 16 digits --- *)
122 2nd MSN for a/b2 0 to 16 digits 0000 0000
132 3rd MSN for a/b2 0 to 16 digits 0000 0000
*) No digits for 1st MSN means, that no MSN is programmed.
MSN means ‘Multiple Subscriber Number’ and is one of your
ISDN-phone-numbers.
Restrictions for NT+2ab/CA restr. and Pairgain:
The MSNs can only be set by authorized persons.

14
Hot Line
Command-No / Meaning Parameter value Default
181 hot line number
for a/b1-interface
0-16 digits ---
182 hot line number
for a/b2-interface
0-16 digits ---
191 hot line switch for
a/b1-interface
0 = hot line off
1 = hot line on
0
192 hot line switch for
a/b2-interface
0 = hot line off
1 = hot line on
0
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 off-
command.
Restrictions for NT+2ab/CA restr. and Pairgain:
a/b1 via a/b1 only; a/b2 via a/b2 only.

15
Emergency Mode Priority Switch
Command-No / Meaning Parameter value Default
210 emergency mode
priority
0 = S-interface
1 = a/b-interface *)
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.

16
Type of Terminal Selection (HLC)
Command-No / Meaning Parameter value Default
221 type of terminal
equipment at
a/b1-interface
(HLC)
0 = audio
1 = telephony
2 = fax gr.2/3
3 = modem(audio)
0
222 type of terminal
equipment at
a/b2-interface
(HLC)
0 = audio
1 = telephony
2 = fax gr.2/3
3 = modem(audio)
0
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.

17
Clear Back Time Delay Switch
Command-No / Meaning Parameter value Default
311 clear back time
delay
at a/b1-interface
0 = immediate
1 = 3 minutes
1
312 clear back time
delay
at a/b2-interface
0 = immediate
1 = 3 minutes
1
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.

18
PABX-Switch
Command-No / Meaning Parameter value Default
320 address selection 0 = standard
1 = PABX
0
If both the a/b-interfaces are connected to a PABX, this parameter
should be set to ‘1’.
Restrictions:
NT+2ab/CA restr.: Can only be set by authorized persons.
Pairgain: Automatically set to ‘1’ and can not be changed.

19
Metering Pulse Switch
Command-No / Meaning Parameter value Default
331 Metering pulses at
a/b1-interface
0 = off
1 = on
1
332 Metering pulses at
a/b2-interface
0 = off
1 = on
1
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.

20
Call Waiting Tone Switch
Command-No / Meaning Parameter value Default
341 call waiting tone
at a/b1-interface
0 = off
1 = on
1
342 call waiting tone
at a/b2-interface
0 = off
1 = on
1
The call waiting tone is a tone in the receiver signaling an incom-
ing 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.
