The SHDSL NTU series (CT-212/CT-213) provides symmetric transmission over a single twisted pair. The CT-212 has a V.35 interface, while the CT-213 have a G.703 E1/T1 interface. Utilizing TC-PAM coding, the CT-212 supports multiple transmission rates of up to 2,320 Kbit/s. In addition to software configurable line rates, the CT-212 also supports rate adaption.
Featuring a powerful remote control capability, the local NTU can perform configuring, PM monitoring, querying, diagnostics and all maintenance functions of a remote NTU via a DSL line. The series are ideally suited to leased line applications such as video conferencing, Internet access, and digital data network (DDN) access.
