The LW-PC系列Protocol Converter gives the interface conversion between G.703 E1 and V.35. ASIC is the core of the design of the protocol converters. With special technologies such as VR Technology, Digital Lock Phase and Clock Extraction Technology and 2 connect with Anti-interference, the software in the equipment is designed with modulation including encode , decode, information insertion, alarm transferring, thus it simplifies the circuit and promotes the reliability of the whole cabinet. This device provide an economical digital access solution for E1 and Fractional E1 network services. With a adapter cable , the Device can link to other DTE Device, such as router, at data rates of 64Kbps. User data is placed into the E1 frame, using only the require number of timeslots. Timeslot assignment is accomplished according to the Data Port speed and manual setting of DIP switches.
◆Based on self–copyright IC.
◆Ethernet transmit transparent through 1-4 E1 channels.
◆Ethernet interface 10M/100M, full/half duplex self-adapt, support VLAN.
◆support AUTO-MDIX, straight and crossover auto-adapt.
◆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.)
◆4 E1 can have 10 ms transmission delay, auto stop transmission when the delay above the limitation.
◆Provide 2 loop functions: local E1 loop, remote E1 loop.
◆MAC address capability:4096
◆ E1 interface according with ITU-T G.703,G.704,and G.823,not support the use of signaling time slot.
◆E1 interface have built-in clock resume circuit and HDB3 codec circuit.
◆Support E1 channel hot plug, and auto detect available E1 channels.
◆Support flexible setting of 1 to 4 E1 channels, auto detect the number of E1 channels and time-delay, select available E1 channels when reset.
◆Support reset remote system from local system.
◆Have Ethernet monitor self-reset function, device will not dead.
◆Network manager interface use SNMP
◆Two types: Standalone, desktop, 19inch;Card,usually be inserted in our rack 19 inch
