[ALUG] OT: ADSL T-Bar?

One of our customers has been advised that something called a "t-bar" (phonetic spelling, I or he may have misheard and I've probably mis-spelled otherwise anyway) will improve his ADSL connection. Professor Google hasn't helped me work out what he is being told, does anyone here know? -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0844 251 1450 Registered in England (0456 0902) @ 13 Clarke Rd, Milton Keynes, MK1 1LG
