Detailed Description  The time-division multiplexing equipment YK-TDMoP1 on packet network can implement the duplex transparent transmission of 1 E1 or transmission of N time slot on the network, and simultaneously provide one network port via the down network port, which supports all traditional E1 and IP service and can access to voice, data, fax, signaling and other telecom services. Such as: if adding telephone access equipment on the two ends, it can access to 30-way telephone, which can fully replace IP telephone on the application, and it is unnecessary to add various gateway equipments of IP under this application mode because it is the complete simulation traditional service, which greatly reduces the cost. Characteristic: Conform to the related provisions of G.703 through IP network transparent transmission framing, non-framing E1 and sub-framing E1 (N*64K) signal; Conform to Metro Ethernet Forum/IETF Pseudo-Wire Emulation Edge to Edge (PWE3) standards One E1 circuit and one 10/100Base-Tx down por Provide L2 or L3 for selecting, when selecting L2, the higher utilization rate of bandwidth can be gained and the more E1 ports can be transmitted on WLAN; when selecting L3, the addressing of transmission packet is based on IP address, and can pass through the exchanger,router and other network equipments; Point to point and point to multi-point connection can meet the requirements of different application; High transmission efficiency can reach the utilization efficiency of 90 percent bandwidth; The smoothness can reach up to 32ms network time-delay Output clock source can select: internal clock, external clock, network adaptive clock or the clock that is picked up from E1 receiving line; When selecting the network adaptive clock, the original clock can be accurately restored through the restored mechanism of TDM clock; the clock is stable and has small jitter and drift, and therefore conforms to the jitter and drift standards of ITU-T clock; The transmission of E1 information on packet switched network has the strict Qos guarantee; Common RJ45 Ethernet interface, 10M/100M self-adaptive; Integrated Ethernet bridge connection; Remote and local network management Convenient use, plug and play, and without complex settings Main Technical Indexes and Functions  1.Indexes of power supply AC Power supply Voltage range 160-240V Power dissipation6W -48V DC Power supply Rated voltage ±20% 2.10/100BASE-TX Indexes of Ethernet interface  Physical interface type RJ-45 Interface rate 10/100Mbps Working mode : full duplex , half duplex ,10/100M self-adaptive Conform to IEEE802.3 standards 3.E1 electrical interface index  Number of sub-circuit 1 Physical interface type RJ45 Input Frequency range2.048Mbps±50ppm Interface code pattern HDB3 Interface impedance: 120Ω (balance) Conform to ITU-TG703 suggestion  4.Operation Environment  Working environment environmental temperature050 relative humidity 2090% Storage environment: environmental temperature-2065 relative humidity1095%
