Co-Directional 64K-RS232/422/485 Converter

Type:FCC-E1tD1/R1/Q1 Message

Description:Co-Directional 64K-RS232/422/485 Converter, Serial port rate 0-14.4K

Product Description

          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.


Functional Properties

?  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;
