kirish

IP-quvvatlash MAX 16E1 portlari orqali TOIP-E1 E1 TDM, TOIP-1E1 IP orqali bir E1 port bo'lib, TOIP-2E1 IP orqali ikki E1 portlar hisoblanadi, TOIP-4E1 IP orqali to'rt E1 portlar hisoblanadi, TOIP-8E1 ustidan 8 E1 portlar hisoblanadi IP, TOIP-16E1 IP orqali 16 E1 portlar hisoblanadi.

TOIP-E1 asosan IP-tarmog'i orqali ovozli signal uzatish uchun ishlatiladi. Bu 1-16 E1 interfeysi, 3, mahalliy chekilgan va 1 uplink Ethernet portiga ega. TOIP-E1 ovozli miqdorda ta'sir holda, standart, arzon narxlardagi simsiz yoki lineate Ethernet / IP konfiguratsiya haqida muammosiz va ishonchli TDM qurilma va foydalanuvchi bir chekilgan ulanishi mumkin. TDM signali uchun shaffof bo'lib, bu model qurilma va ovozli pochta tizimi signalizatsiya PBX, mobil tayanch stantsiyasiga, SS7, deb muammosiz har qanday qurilma jismoniy E1 interfeys, ulanish ishontiradi. Bu, masalan, LAN, WAN, MAN va simsiz tarmoq sifatida E1, asoslangan aloqa tizimida foydalanish mumkin.

E1 TDM over IP converter Providing emulation E1 channel through Ethernet, the difficulty is rebuilding timing information of E1 code stream effectively at the exit of network. The special disadvantages of Ethernet itself, such as random packet delay, without effective timing transmit mechanism, transmission error or collision that brings on packet lose, must be conquered. Our company resolves the difficulties above faultlessly through availing ourselves of technical advantage and adapting advanced clock disposal technology. TOIP-E1 encapsulates the date of E1 code stream to the packet and transmits it to the remote device through Ethernet. This model has two method of encapsulation for optional: Ethernet encapsulation simplicity and UDP/IP protocol encapsulation. The former is suit for the connection of the same Ethernet subnet, because it has high encapsulation efficient especially suited to the occasion of bandwidth intensity, such as interconnection based on the wireless network bridge.  But it can’t span router. The latter is suit for the inner net connection of IP net, with the advantage of making use of router or 3-layer switch. But the disadvantage is that the addition IP header needs extra bandwidth. When adapting 128B encapsulation, each E1 channel will take up 500kbps more than Ethernet encapsulation simplicity, with lower transmission efficiency. User can select different encapsulation type based on practical usage occasions.
