Before you set up and connect your Ascom Eurit 25, check the contents of the package carefully
for
• damage to the actual packaging, which may indicate that the phone has been damaged in
transit!
• visible damage to the handset or phone!
• damage to the connection cords, e.g. to the connectors or cable sheathing!

Positioning
Place the Ascom Eurit 25 on an even, dry surface within range of the connection socket
(NT+2ab or wall socket). If the selected position is too far from the connection socket, use an
approved extension cable which you can buy from a specialist dealer.
The phone is designed for normal operating conditions. Modern furniture features a wide range
of varnishes and plastic veneers and is treated with a large number of different polishes. Some
of these agents may contain ingredients that corrode and soften the plastic feet of the phone. If
this happens, it may leave undesirable marks on the furniture surface. Understandably, Ascom
cannot accept any liability for such damage.
➭ Make sure the telephone connection cord is safely stowed to prevent tripping on it.
➭ Do not plug the connection cord in sockets other than the one for which it is intended.

When applying for your ISDN connection from your network provider, you will have received at
least three numbers for your connection (Your Eurit 25 supports 3 numbers). These numbers
can be assigned to different devices or programmed on your Ascom Eurit 25 as user-specific
numbers (MSN). For example, a different ringing tone melody can be set for different MSNs.
If you have not set an MSN for your phone, it will ring whenever any of the assigned numbers is
called, even if you have assigned one of them to another device e.g. a fax machine.
To get the best out of your Ascom Eurit 25, you must set at least one user. This is done
automatically by giving the phone an MSN. See the section on »Additional settings« for how to
assign other users.
➭ You cannot assign the same MSN to several users.

This section describes the various options your Ascom Eurit 25 offers on the ISDN connection.
All options listed here are valid for all users you have assigned to the phone. See »Additional
settings« for how to assign three different users. This describes the different settings which can
be made for different users.
Your Ascom Eurit 25 can also be operated in conjunction with a PBX with the same options as
listed below. The range of additional features available to you and how you use them is
dependent on the PBX type. See »PBX access« in the Attachment for how to connect your
phone to a PBX.
➭ All options listed below assume that at least one MSN (Multiple Subscriber Number) and
one user has been set, as described in the section on »Startup«.
User conceptUser concept
User conceptUser concept
User concept
The Ascom Eurit 25 allows you to assign three different users to a single phone. For example, if
you use the phone at home you can set it for the following users : »Mother«, »Father«, and
»Daughter«, or for business purposes for »Company«, »Club« and »Private«. You can switch
from one user to another by pressing the user key. The display shows the active user’s code (A,
B, C).
Once you have defined the relevant settings for each user, your Ascom Eurit 25 handles various
functions individually depending on the set user.
For every call the active user makes, his number is presented to the called party. Incoming calls
are distinguished from outgoing calls and displayed in the caller list. The phone calculates the
charges separately for each user. Calls can be diverted according to the user’s requirements etc.
