4channel Voice Fxs Fxo Over E1 Multiplexer - China

price: contact company for price

voice(POTS/FXS/FXO) multiplexer which realize 4channel voice and

ethernet over E1 transmission. voice support FXS or FXO port, ethernet

support 1*10/100M.

1 Function

The 4 Voice and ethernet multiplexer can provides 4voice and 10/100Mbase-T Ethernet over G.703 E1 converter. The 4 voice and ethernet over E1 converter realize the long-distance extend of telephone line through E1 channel. 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.

The voice and data 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 4voice and ethernet to E1 interface converters widely used for LAN and Wan networking, control, and so on, and particularly applicable with a single E1 channel access data and voice at the same time.

2 Features

provides 1 channels Ethernet connectors;

10M/100M, full half duplex self adapt, support VLAN;

The Ethernet interface supports AUTO-MDIX( cross over and straight through self adapt);

provides two clock types: E1 master clock, E1 line clock;

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;

realize the automatically rate set of local device to remote device;

has the function of pseudo-random code testing, convenient for opening of the circuit, and can be used as an error code instrument;

Ethernet supports rate of N*64k (N=1-32), which can be regulated from 64K to 1098K;

supports 75Ω unbalanced and 120Ω balanced impedance at the same time;

Provide Ethernet auto reset function, run more stably;

various Ethernet data indicate functions, which indicate data transmission status timely;

Provides 1-4 voice channels, support calling indication;

Voice connector FXO (FXS), FXO connect to PBX and FXS connect to phone;

support 4 wire E&M.
