8 FXO/FXS E&M to E1 PCM multiplexer:PCM-E08

8 FXO/FXS E&M to E1 PCM multiplexer:PCM-E08PCM-E08:8 Voices(FXO/FXS,E&M) over E1 PCM MultiplexerIntroducePCM-E08 provides  conversion  between  ITU-T  G.703  standard  E1 framed interface and 10/100Mbase-T Ethernet interface, and provide 1-8 voice  through E1 channel, realizing the long-distance extend of telephone line through E1 channel. It also  provides one RS232 data channel. E1    signal can transmit through fiber optic multiplexer, connecting the two local networks into two parts of one network. It is a high-performance, multi-type long-range Ethernet bridge. Its 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.  It  can  study  the  MAC  addresses  of  the  LAN  that connected incessantly, automatically; also can transmit aim address as frames of another LAN. Be transparency to TCP/IP protocol, providing safe, seamless connectivity for different devices in the network. E1-10/100BT  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 data and voice access at the same time. RS232 asynchronous transmission rate is300-115.200 kbps self-adapt.
