V.35/E1/10Base-T G.SHDSL Modem
NIT-EN NIT-EB

Adopted the advanced G.SHDSL technology, extends the E1/V.35/Ethernet digital signal on 2-wire copper line (24 AWG/0.5mm), the range is up to 5km without repeaters, user selected rates is Nx64Kbit/s(N=1 to 32). It's the best way to speed up for the loop line of the last mile access. So as to keep value from the current resources, thereby protects the investment of users.

Features

> Comply with ITU-T G.991.2 > E1/V.35/10/100Base-T interface > E1 frame/unframe can be selected > E1 Speed: 2048Kbps Nx64Kbps(N=1 to 32) > V.35 speed :NX64(N=1 to 3236) > With the range being 5km (24AWG,0.5mm) > Local and remote loop back test > Stand alone style and card style product > Power: DC or AC > Communicates with the third part G.SHDSL products.
