Description

64k-V.35 / V.24 interface converter provides ITU-T co-64K G.703 standard E1 interface and standard V.35 conversion interface between the physical layer / V.24.

The G.703 (Co-Directional G.703) interface divides 64Kbps cycle into 4 unit intervals, it uses“0101” represent “0”, “1100” represent “1″. By alternating transformation polarity of the adjacent block, binary signals convert three-level signals. In every 8th group destroyed block of alternating polarity, thus to transmit 8KHz timing signal. By the above coding, G.703 co-directional 64Kbps signal could achieve transmitting the timing signal of 64KHz and 8KHz and 64KHz and the data signal of 64Kbit/s in the same direction with a pair balanced line.

This interface converter provides one co-directional G.703 interface and one Ethernet interface to achieve 10/100Base-T Ethernet data transmission on the G.703 channel. It is a high performance, self-learning Ethernet bridge. This device is the extension device of Ethernet, using network (PDH/SDH/Microwave) that provide G.703 channel to achieve local and remote Ethernet interconnecting with serial interfaces at a lower cost. The device has inter-set loop test function to facilitate the project launching and daily maintenance.

Features

Based on self -copyright IC.
Can Realize Ethernet data transmission in one Co-directional G.703 circuit.
Inter-set dynamic Ethernet MAC address (4,096) with local data frame filtering.
The local device can manage the remote device.
Have the function of G.703 loop back check, and indicate on LED.
Can differentiate the reason of Co-directional G.703 lose signal is that the remote device power-off or directional G.703 line broken.
Ethernet interface supports 10M/100M, half/full duplex auto- adaptable, supports VLAN.
Ethernet interface supports AUTO-MDIX (crossed line and straightly connected line self-adaptable ).
Provide 2 clock types: Co-Directional G.703 master clock and G.703 line clock.
The local device can forced the remote device rate follow it(when the device is unframed mode, that is invalid).
Have three Loop Back Mode: G.703 interface Loop Back (ANA)、Ethernet interface Loop Back(DIG)、Command the remote Ethernet interface Loop Back(REM).
Support self-adaptable 120 Ohm balance.
