Contact: amily[at]veecom dot com dot cn GVE-Tplus is an upgrade of GVE-T. 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. GVE-Tplus can not only be set up into GVE-T, 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. GVE-Tplus 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. 245mm*215mm*50mm
10/100 MBPS managed media converter Managed Media Converter is a 10/100Base-TX auto negotiation and auto MDI/MDIX cable selection Fast Ethernet Media Converter with intelligent network management that translates transmission signals from a twisted-pair 10Base-T or 100Base-TX cable to 100Base-FX fiber optic cable. It enables network managers and network operators quickly isolate problems without visiting multiple wiring closets, avoiding expensive downtime. With its SNMP manager, user can monitor and configure the Copper Port and Optical Port of center chassis and remote standalone easily.

Telecom PTC Thermistor Description This series of ceramic PTC (positive temperature coefficient ) thermistors help provide protection against power cross, power induction surges and lighting surge defined in ITU, Telcordia, UL. Available in chip, radial-leaded coated and non-coated, SMD, twin vertical surface mount configuration. PTC thermistor overcurrent protector provides reversible, self-resetting protection against over-currents of telecommunication line protector units, improve the reliability of custom premises and network equipment. Ceramic PTC thermistors can be found providing re-settable line protection at the exchange, monitoring hot spots and protecting ringers, battery feeds, transformers and relay circuits. Also used extensively to protect the mobile phone's battery pack against overcharging in land-based and radio mobile communications. Advanced developments in telecom equipment in recent years have radically altered the protection requirements of both exchange and subscriber equipment. The PTC thermistor must protect the telephone line circuit against overcurrent, which may be caused by the following examples: Surges due to lighting strikes on or near to the line plant. Short-term induction of alternating voltage from adjactent power lines or railway systems, usually caused when these lines or systems develop faults Direct contact between telephone lines and power lines. To provide good protection under such conditions, a PTC thermistor is connected in series with each line, usually as secondary protection; However, even with primary line protection (usually a gas discharge tube), the PTC thermistor must fulfill severe requirements. Surge pulses of upto 2KV can occur and in order to withstand short term power induction, the PTC thermistor must withstand high voltages. If the line has primary protection, a 220V to 300V PTC thermistor is adequate. Without primary protection, 600V PTC device is necessary. We can manufacture a series of PTC thermistor fulfilling both requirements. Typical Application of PTC Thermistor in Telecommunication Protection Central Office Switching Equipment (C.O), analog and digital line cards, T1/E1 equipment, xDSL modems and splitters, multiplexers, CSU/DSU, servers. Primary Protection Modules, MDF (main distribution frame) modules, network interface devices (NIC). Custom Premises Equipment, also known as subscriber terminal equipment (T.E.), IT equipment: Modem, phone sets, fax machines, phone wall outlet (plugs), alarm systems, answering machine, PBX systems, ADSL Splitters, internet appliance, POS terminals.
