During the registration process, you will be asked if you want to continue using your current (fixed) telephone number or you want a new fixed number. If you have indicated a new number, this will be done by our InterXS team. A regional fixed number will then be assigned to you. Have you chosen a number? Then your phone number will be sorted to InterXS so you can continue using it without any problems.

The Net Service Number (NSN) is a number that is connected to the VDSL internet line (copper connection). The NSN-number is usually unknown to you as a customer because it is not actively used. The NSN-number is used for administrative purposes, so that a line on which no fixed connection is active, can be managed. With the NSN number we can recognize your copper pipeline.

The NSN number is important to you when you move or transfer from another provider. With the help of a valid NSN-number on the new internet address, we can connect the internet signal on the same line. Normally, no electrician is required to the fusebox (UP). Usually the NSN-number can be requested from the previous provider to whom the connection last belonged.

We always try to connect you on the existing NSN-Number. Sometimes, the NSN number can not be found, or does not yet exist. In this case, a new NSN-number must be requested. In order to activate your subscription on a new connection, an electrician is required, to activatie the terminal in the fusebox. This is a simple operation. Unfortunately the additional costs for the customer are not included in the subscription.

Due to the scarcity of IPv4 addresses, we use a (private, and therefore not externally accessible) Carrier Grade NAT-IPv4 address. This means that services such as Portforwarding are not possible. You will receive a fixed /64 IPv6 address from us. The internet service and telephone service works best on this. Sometimes it happens that customers need an IPv4 address for certain internet services. The disadvantage of this is that the telephone service only works via an IPv6 connection. However, because these IPv4 addresses are scarce nowadays, we have to charge additional costs for this. For 5 CHF per month it is possible to obtain an additional public/static IPv4 address. Both options function again. If you are interested in this, please let us know by e-mail after you have registered with InterXS.
