8x E1 to 4x Ethernet 10/100 Base-T Interface/ Protocol conve er uses reverse multiplexing technology to transmit 10/100BaseT data with bonding multi E1 channels, thus realizing conversion between 1-8 E1 channels and Ethernet interface. It can transmit signals point-to-point from E1 channel to RJ45 interface to realize connection between E1 channel and Ethernet Lan.
The 8E1 to ethernet conve er provide 8E1 po and 4 x 10/100M ethernet po s. Line rate is 1968Kbit/s for one E1 channel and bandwidth can reach 15744Kbit/s for 8 E1 channels. When used in 10/100Mbps half/full duplex mode, this equipment can be connected with Ethernet switch or hub (integrated circuit machine) to expand transmitting distance and application scope of Ethernet by making full use of large number of E1 channels in current telecommunication network.
The 8E1 to ethernet interface conve er is an excellent solution for connecting Ethernet broadband. This product can be applied in many fields such as connection of LAN and end offices, video ordering (VOD), remote monitor and E1 interface of switches.
Features:
- According with IEEE 802.3, suppo 10Base-T, 100Base-T. - 4 Ethernet po s available
- Suppo flexible setting of 1 to 8 E1 channels, auto detect the number of E1 channels and time-delay, select available E1 channels when reset.
- Provide 2 loop functions: local E1 loop, remote E1 loop.
- Ethernet transmission transparent,suppo AUTO-MDIX, straight and crossover auto-adapt.
- Can transmit super-long frame of IEEE 802.1Q, suppo Ethernet switch with VLAN function.
- Suppo E1 channel hot plug, and auto detect available E1 channels.
- Suppo reset remote system from local system.
- 8 E1 can have 10 ms time-delay, CRC alarm limitation can auto insulate bad-quality transmit channel by configuration, and is single direction insulation. when one direction error rate over limitation, cut only this direction, the other direction not affected. ( the two directions need not symmetry.)
- Power supply option: AC220V, DC-48V. The positive and negative terminal can be exchanged for DC-48V, easy for installation and maintenance.
- Suppo s NMS monitoring po via RS-232
