What cables do I need to use the TP link to-w8969 for wireless no phone

You need a good quality phone cord to get the DSL signal from your wall plate to the TD-W8968 modem/router.

Are you asking is you can use this without a DSL connection? If so, it can serve, with a few setting changes, as a singe wifi access point without any cables or as part of a LAN with an Ethernet cable connected to the LAN port on the back.
