Scarab-E : SHDSL-CPE (Ethernet modem)

Scarab-E is a stand alone device which provides an interface between SHDSL and Ethernet network. It provides layer two bridge functionality between SHDSL and Ethernet interface. Local craft terminal (LCT) via RS-232 and LED are used as OAM&P function for maintenance and management personnel.

 

One Scarab-E has to configure as CO (LTU) side and the other as RT (NTU) side, both Scarab-E use local power with external AC to DC power adapter. User can connect PC or server to Scarab-E Ethernet port directly or use Ethernet switch/hub for multiple PC or server connection. This point-to-point architecture provides customer a simple distance extension of Ethernet link via SHDSL using existed twisted pair copper wire. If the carrier use ADSL modem but require longer transmission distance, Scarab-E (Ethernet modem) is a good solution.
