B-ISDN terminal adapter (B-TA)
Terminal adapters (B-TA) are adapters in the subscriber area of B-ISDN.
They enable terminal devices according to TE-2 or B-TE2, i.e. devices that are either not broadband-capable or broadband-capable terminal devices that do not comply with the ITU specifications for interfaces at the reference points T(B) and S(B), to adapt to the B-ISDN network.
