1 Function
The 8 voice POTS (FXO/ FXS) over E1/ G. 703 multiplexer can provides 4*10 (100) BaseT+8*voice +1 RS232 over E1 converter. The 8 voice POTS (FXO/ FXS) over E1/ G. 703 multiplexer realize the long-distance extend of telephone line through E1 channel. It is small size, low cost and very appropriate to the cost-sensitive bridging applications, or as spaces become an extension of the LAN infrastructure, devices or above devices.
The voice POTS (FXO/ FXS) over E1/ G. 703 multiplexer can automatically connected to the LAN with its uninterrupted learning the MAC address and the address as another purpose of the frame relay LAN. The 8voice and ethernet to E1 interface converters widely used for LAN and Wan networking, control, and so on, and particularly applicable to the network users to the network users with a single E1 channel access data and voice at the same time.
2 Features
