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 2. NTBA 3. Pairgain S- and a/b-interfaces available Only S-interface available 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.
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.
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.

Start: Hook off Dial

Input command number Input parameter value Dial
Setting over? End: Hook on
5. Table of Configuration Commands
Parameter-Reset Command-No / Meaning 010 reset of all parameters to the default value Parameter value 1 Default ---
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. 12
Multiple Subscriber Number (MSN) Command-No / Meaning Parameter value 111 1st MSN for a/bto 16 digits 121 2nd MSN for a/bto 16 digits 131 3rd MSN for a/bto 16 digits 132 1st MSN for a/b2 2nd MSN for a/b2 3rd MSN for a/bto 16 digits 0 to 16 digits 0 to 16 digits
Default --- *) --- *) 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. 13
Hot Line Command-No / Meaning 181 hot line number for a/b1-interface 182 hot line number for a/b2-interface 191 hot line switch for a/b1-interface 192 hot line switch for a/b2-interface
Parameter value 0-16 digits 0-16 digits 0 = hot line off 1 = hot line on 0 = hot line off 1 = hot line on

Default ----0 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 offcommand. Restrictions for NT+2ab/CA restr. and Pairgain: a/b1 via a/b1 only; a/b2 via a/b2 only. 14

Emergency Mode Priority Switch Command-No / Meaning Parameter value 210 emergency mode 0 = S-interface priority 1 = a/b-interface *) *) First hooked off, first served

Default 0

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. 15
Type of Terminal Selection (HLC) Command-No / Meaning Parameter value 221 type of terminal 0 = audio equipment at 1 = telephony a/b1-interface 2 = fax gr.2/3 (HLC) 3 = modem(audio) 222 type of terminal 0 = audio equipment at 1 = telephony a/b2-interface 2 = fax gr.2/3 (HLC) 3 = modem(audio)
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. 16
Clear Back Time Delay Switch Command-No / Meaning Parameter value 311 clear back time 0 = immediate delay 1 = 3 minutes at a/b1-interface 312 clear back time 0 = immediate delay 1 = 3 minutes at a/b2-interface

Default 1 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. 17
PABX-Switch Command-No / Meaning 320 address selection
Parameter value 0 = standard 1 = PABX
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.
Metering Pulse Switch Command-No / Meaning 331 Metering pulses at a/b1-interface 332 Metering pulses at a/b2-interface
Parameter value 0 = off 1 = on 0 = off 1 = on

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.
Call Waiting Tone Switch Command-No / Meaning 341 call waiting tone at a/b1-interface 342 call waiting tone at a/b2-interface
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. 20
Metering Calculation Command-No / Meaning 380 amount for one metering pulse 390 currency factor Example for US$: 1 pulse = 10 cents, thus dial
Parameter value 1 to 8 digits 1 to 8 digits
Default country specific country specific
1 US$ = 100 cents, thus dial
Restrictions for NT+2ab/CA restr. and Pairgain: Can only be set by authorized persons. 21
Calling Line Identification Restriction (CLIR) Switch Command-No / Meaning Parameter value Default 411 CLIR at 0 = ident. restr. 1 a/b1-interface 1 = ident. allowed 412 CLIR at 0 = ident. restr. 1 a/b2-interface 1 = ident. allowed 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. 22

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

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 # 1st MSN for a/b1
3. When the permanent tone is switched on proceed to 4 and 4.

# HLC for a/b1

5. When the permanent tone is switched on, hook on. 24

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.

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, inform your network 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.
