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

Introduce
PCM-E08 PCM equipment 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 PCM equipment. 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 is
300-115.200 kbps self-adapt.

Features
01.Realize long-distance monitoring of local device to the remote device based on self-copyright IC
02.Provides 4 channels Ethernet connectors
03.10M/100M ,4 Ethernet nterfaces, 10M/100M, full half duplex self adapt, support VLAN
04.The Ethernet interface supports AUTO-MDIX (cross over and straight through self adapt)
05.Ethernet interfaces support channel separate function, can set VLAN based on TAG
06.Provide two clock types: E1 master clock, E1 line clock;
07.Provides 3 kinds of loop-return function, namely E1 self-looping at local end, Ethernet self-looping at local end, ordered to self-loop at remote end;
08.Realize the automatically rate set of local device to remote device
09.Have the function of pseudo-random code testing, convenient for opening of the circuit, and can be used as an error code instrument;
10.Ethernet supports rate of N*64k (N=1-32), which can be regulated from 64K to 1098K;
11.Supports 75Ω unbalanced and 120Ω balanced impedance at the same time;
12.Various Ethernet data indicate functions, which indicate data transmission status timely;
13.Provides8 voice channels, support calling indication;
14.Voice connector FXO (FXS), FXO connect to PBX and FXS connect to phone;
15.RS232 channel can transfer asynchronous serial data with self-adaptable baud rate of 300 to 115.200;
