DNT2Mi provides an n x 64 kbit/s (n = 1 to 32) data access and enables TDM multiplexing of line rates to three n x 64k ports. It also incorporates V.110 rate adaptation enabling port rates lower than 64 kbit/s.

DNT2Mi provides an n x 64 kbit/s (n = 1 to 32) data access and enables TDM multiplexing of line rates to three n x 64k ports. It also incorporates V.110 rate adaptation enabling port rates lower than 64 kbit/s.

The line rate is n x 64 kbit/s (n = 3 to 32 in two-wire connection; n = 6 to 32 in four-wire connection but only even numbers can be used), and the Trellis Coded Pulse Amplitude Modulation (TC-PAM) coding is used for transmission.
