TST-CON08 can realize the conversion of multiple E1 and Ethernet interface. This equipment can implement the point-to-point transmission of MAC frames through one to eight E1, and automatically inspect and use the effective E1 channel; the highest transmission rate is 16Mbps, which can very conveniently extend the application range and transmission distance of Ethernet.
   TST-CON08 (Ethernet/8E1 converter) has many good points including high integration, strong reliability, low power dissipation, small volume, complete function, etc., and the greatest advantages include: wide transmission channel, good protection for transmission channel, and stable working under the bad environment. The installation of whole body has not any adjustable point, with convenient use and simple maintenance.
