Do You Have An Isdn House Installation - Cablecom ISDN Mode D'emploi

The multiple subscriber number (MSN) must be set.
Step 5
Before you can use the digital phone service with the ISDN telephone adapter, you
must set the multiple subscriber number MSN for each of your ISDN phones (see the
user manual for your ISDN telephone). Only then will the ISDN telephone ring for the
correct number.
Important: For your existing ISDN telephone, you had to enter the telephone
number in the telephone. In contrast, with our service you don't set the
telephone number but simply enter 1 for the main connection (Line 1) or 2 for
the additional connection (Line 2).
Example: You have two phone numbers:
Main connection (Line 1): 044 535 1111
Additional connection (Line 2): 044 535 1112 (assuming you ordered two lines!)
• The ISDN telephone, whose MSN is programmed with 1, rings when a call is received
for «044 535 1111». The number for outgoing calls is also «044 535 1111».
• The ISDN telephone, whose MSN is programmed with 2, rings when a call is received
for «044 535 1112». The number for outgoing calls is also «044 535 1112».
You can find other examples of how to program MSNs in chap. 6 under
«Tips and tricks».

3 Do you have an ISDN house installation?

You can continue using your existing ISDN house installation with the ISDN
telephone adapter. For information on adapting the installation contact our
partner company Dipl. Ing. Fust under 0848 559 111 or your own electrician/
telecommunications engineer.
Only for technical personnel
The existing sockets in a house installation can continue in use if you remove the
ISDN-NT device from the U and S interfaces. The ISDN-S0 interface of the ISDN
telephone adapter can be directly connected to the ISDN-S0 bus of the house
installation. The two S0 interfaces of the ISDN telephone adapter are terminated
with 100 ohm. If there is a cabling for analog telephones you can directly connect
the analog port of the cable modem to the analog socket of the house installation.
It is important to ensure that there is no connection to the U interface.
