ISDN splitter and Fritz!Box ADSL router

I have currently an ISDN (Switzerland) Telephone connection which uses a splitter between the NT telephone box and the digital telephone line into the building.  
The splitter is connected to an ISDN modem which then goes onto a firewall which is the DHCP server for a network.

Soon our telephone company is implementing a change and the NT box will be replaced with a combined telephone and DHCP configured LAN router with integrated firewall and WLAN.   (Fritz!Box Fon WLAN 7270)

(Now I could attempt to set this new device with all of the current settings for IP adress and VPN ..... but it is rather a bit of work).

For me the simplest is just to have the splitter between the incoming line and this new device - so it is basically just for the telephones and the current LAN etc is not affected at all.  
On the setup instructions it states one should connect this new device directly to the incoming line.  

Would it create physical damage if I left the splitter in place as it currently is (between the incoing line and the Fritz!box) ?
Would that likely result in nothing working (phones and or internet) even if there was no physical damage ?
