Conveter (COGVE):
Features:
1) V-COGVE, which is based on electrical design technology, is a protocol
converter between G.703 co-directional 64Kbps data gateway interface and
V.35 or V.24 on PDH or SDH device
2) Co-directional G.703 interface divides 64Kbps cycle into four units space,
0101 indicates "0", 1100 indicates "1", by this way of exchanging the polarity
of numbers (next to each other) to convert binary signal into three electrical
level signal
4) Polarity exchange of every eighth breakage code is also done to transmit 8k Hz
time signal. By dealing with these codes, G.703 co-directional 64KBps can
converts 64k Hz and 8k Hz of time signal and 64Kbit/s data signal with a pair
of balance lines on the same direction
4) To full duplex communication, two pairs of balance lines (four lines) are enough
for interface. So, no other balance line is needed for inversed interface and
middle interface to transmit time signal of clock
