connecting soil waste to old clay pot

[nottsrob184]

Hi all.
I;m installing an upstairs wc into a 1950's property. Its currently got a plastic collector from the bathroom bath and sink into a 68mm (i think)downpipe that just sits into the ground surronded with concrete and goes into a 110mm clay pot drain.
The rim of the clay pot is damaged slightly. What do i need to connect a new plastic 110mm waste downpipe directly to the pot?.
Thanks for any help or direction.

the clay pot drain may be a gulley -like a large diameter trap- not suitable for a soil pipe connection Best to investigate further
