MPG⁺ Series: TC - PAM version     

SHDSL-Digital Pair Gain System

Exartech MPG⁺, an SHDSL (Symmetric single pair High bit rate DSL) Digital Pair Gain System, conveys uncompressed PCM Voice channels in it. This system provides 4/8/12 voice channels over a single twisted pair subscriber line. MPG⁺E provide an SHDSL (G.SHDSL) interface by using existed twisted pair between RT and LU. It can support POTS (Voice) and Ethernet interface (e.g. Internet access) as your wish. With Exartech Scarab-E (Ethernet modem), MPG⁺E can extend Ethernet transmission distance to 2~5 Km by SHDSL.

MPG⁺ series are mainly used to meet the demand of subscribers (or potential subscribers) at those areas, where the number of subscriber lines cannot be expanded in proportion to the increase of subscribers. Without digging ground or placing cable, it immediately solves subscriber line shortage problem.
