SW 7232 E1 G.703 Modem

---

   This model applies reverse multiplexing technology to transfer 10M/100M Ethernet data by using E1s. It realizes conversion between 1 to 8 E1 channels and Ethernet interface (fiber or copper).  One E1provide capable of providing a real Ethernet throughput of 1.984 Mbps, Total 8 E1 provide throughput of15.872Mbps respectively. And it also automatically adapted to lower data rates from 2Mbps, in case that less E1 circuits is employed.
