Single E1 protocol converter E1 to Ethernet bridge interface converter photoelectric switch (Non-frame)details:

Basic information:

Single E1 protocol converter is the company using the self-developed special reverse multiplexing equipment development and production of integrated circuits, the Ethernet packet multiplexing transmission in E1 1 road, can be very convenient to use public sites in existing rich resources of E1 rapidly to form a broadband Ethernet data network. The product of E1 channel without any special requirements, and can the E1 automatic fault tolerance, when the ring back to the E1 channel, equipment automatically banned Ethernet data transmission, to avoid impact downstream switches. Protocol converters, flexible configuration, simple maintenance, at the same time provide a complete network management functions.

Function description: the frame into a single E1 (75 Ω non-equilibrium) ether, in HDLC protocol, the Ethernet interface is 1 x 10/100 base - Tx, support the E1 loopback detection, support for BERT, local CONSOLE management, remote management of belt
