The cable you describe is fairly standard these days for connecting phones
to cat 5 because, as Shay says, a lot of cable installations simply put cat
5 everywhere and don't use separate phone cables - especially with the
advent of IP phone systems that run over Ethernet.

You don't actually need these cables to plug phones into cat 5, the RJ11 (6
pin for phones) will fit into the middle of a RJ45 (8 pin) jack. Purists
don't like to do this because, after a time, it creates a difference in the
tension of the 6 middle pins and the 2 outer but it isn't that significant.

Your alternative of course is to simply put a hub or switch in the senior
room and "uplink" to the Airport over the LAN seeing as you have a cable to
the room.

Or, if you don't have the senior room cabled, connect one Mac using the
cable and use software base station to create another Airport network. I'm
not sure of the impact of this with the overlapping network coverage as the
Airport isn't, to my knowledge, cell based like it's big brother Lucent's
WaveLAN. But, perhaps, if you create a different network on a separate
channel it will work.

I hope this give you a few ideas.
