TDMoIP

Introduction: TDMoIP device is mainly used to transmit voice signal in the IP net, have 1~4 E1 interface, 1 Ethernet local port and 2 Ethernet uplink port. TDMoIP can seamlessly connect TDM device with user’s Ethernet on the standard low cost wireless or wire Ethernet/IP configuration without affecting the voice quality. TDMoIP is transparent to the TDM signal. Assured seamless connect to any device of physical E1 interface. Such as PBX, mobile base, SS7 signal device and voice mail system. It can be used in the communication system based on E1,such as LAN,WAN,MAN and wireless net. Provide veritable E1 channel through Ethernet, the difficulty is rebuilding timing information of E1 code stream effectively. Must overcome Ethernet’s disadvantage such as packet delay random,without effective timing transmit mechanism,transmit mistake code and lose packet for collision. Ebang resolves the difficulties above faultlessly through it technology advantage and adapting advanced clock manage technology, TDMoIP encapsulation the data of E1 code stream to the packet, transmit it to the remote device through Ethernet. This device has two method of envelop: Ethernet envelop simplicity and UDP/IP protocol envelop. The former is suit for the connection of the same Ethernet subnet, because it has high encapsulation efficient. Especially suit to the occasion of bandwidth intensity, such as interconnect based on the wireless network bridge but can’t span router. The latter is suit for the inner net connect of IP net, it advantage is that it can make use of router or 3-layer commutator. Span the Ethernet segment, the disadvantage is the addition IP header need extra bandwidth, when encapsulation adapting 128B, every E1 take up 500kbps more than Ethernet envelop simplicity, the transmission efficient is low. User can select encapsulation model based on the practical usage occasion. Characteristics: 1. Thorough IP net transmit frame,non-frame and frame fractional E1(N*64K)signal Transparently, confirm to G.703; 2. High transmit effect, low transmit delay; 3. Provide 1/4E1 channel and10/100Base-TX download interface, universal RJ45 Ethernet interface, 10M/100M auto-adapt; 4. Ethernet packet length can set, sustain long packet; 5. User can select IP protocol encapsulation and simplicity Ethernet envelop 6. Support VLAN; 7. Support Ethernet ping function. 8. Support package loss indicator function for E1 transmission line by LOS and AIS. 9. Point to point ,point to many points connect, satisfy different application demand. 10. High efficient transmission, can up to 90% bandwidth usage efficient; 11. Support 75Ω and 120Ω interface auto-adapted; 12. 10/100M Ethernet, full/halt duplex auto-adapt, auto-MDIX; 13.When select net adaptation clock, can resume originality clock exactly through TDM clock resume device, clock stable,jitter and excursion small, conform to ITU-T clock jitter and excursion standard; Parameter and index: E1 interface 1.
