IC-GVL:E1 to V.35/V.24 and Ethernet Converter

E1 to V.35/V.24 and Ethernet Converter

E1 converter

G.703 to x.21

More details

E1 to V.35 and Ethernet Converter:IC-GVL

E1 to V.35/V.24 and Ethernet Converter

Multifunctional all-purpose E1/G.703 to V.35 and LAN three-in-one multiplexer, also named three-in-one interface converter

IC-GV plus can convert E1 to V.35 interface and LAN interface. Bandwidth of every port can be set up into N*64Kbps(N=1--31) continuous data stream, but the total bandwidth of the two ports must be no more than 31 and must be inserted into PCM time slot of E1. It sustains alternative CRC4 ON/OFF, CAS/CCS (30 & 31 time slot).

Rate distribution for each port is performed by an independent 5-bit switch.

Can distribute E1 to LAN interface and sustain framed N*64Kbps(N=1--31) and unframed 2048Kbps which is also named fractional and unfractional

Ethernet UTP interface has function of VLAN802.1Q.

10/100 Base-T(UTP) LAN interface accords with IEE802.3/Ethernet work mode: full duplex / half duplex physical interface: screen RJ-45 across and direct connection optional

There have two transmitting mode to choose: data and image.

Can distribute E1 to V.35 data interface Work mode can be internal clock and slave clock, or N*64Kbps(N=1--31) external clock to perform end-linking line.

Can be set up into remote Ethernet bridge from V.35 to LAN. With low cost, it is fit to be used in bridge connected which is sensitive to cost or in LAN as stretcher or subsection.

Satisfy with requirements of G.703, G.704 and G.706 of ITU

With local and remote loopback, consumer can conveniently test lines and diagnosis faults to perform integrality test by port-to-port.

Many director lights on the front panel display work state and alarm signal of equipment.

G.703 line interface: impedance 120ohm(RJ45)/75ohm(BNC) optional

Having two kinds of machine model: standalone and rack mountable power supply: -48V DC or 220V AC optional


IC-GVL is an upgrade of IC-GV. It is based on the ASIC circuitry design technology. It is a multi-functional, multi-purpose E1/G.703 to V.35 and LAN three-in-one multiplexer, which is also knowns as the three-in-one interface converter. 

IC-GVL can not only be set up into IC-GV, but also can distribute the whole E1 capacity to V.35 data interface, although E1 must be framed N*64Kbps(N=1--31). The work mode can be either internal clock and slave-clock, or N*64Kbps(N=1--31) external clock to achieve end-linking line.

IC-GVL can be set up into long-range Ethernet bridge from V.35 to LAN interface. With low cost, it is suitable for use in bridge connection which is sensitive to cost or use in LAN as a stretcher or subsection. It can learn automatically MAC address in the connected LAN and only transmit the aim address to frame in another LAN. There are more than 10000 addresses in its LAN table. And they can be updated automatically. The highest speed of filtrating and transmission is 30000 frame/second(line speed). The buffer size is 64M. The throughput delay is 1 frame. When it is used as a stretcher or subsection, it can forbid filtration so that all traffic can be broadcasted in WAN. 10baseT interface can run in full duplex Ethernet with topology and improve data throughput by eliminating filled blanks in the 64 bytes frames. Without any negotiation in V.35 port, it is specially suitable for use in satellites and other wireless broadcast.
