Front Panel Introduction of Mainframe
2.Function Card Rear Panel on Mainframe:
2.1Ethernet Interface
There are 2 RJ45 ports, providing 3 Ethernet interfaces (100M bandwidth shared) and these two Ethernets are a shared exchanger, which can transmit on optical fiber simultaneously. The Ethernet interface supports automatic recognition/adaptation of cross-wires and direct-type-wires, ridding the trouble of remaking the wires
2.2VOICE Interface
It provides a DB37 physical interface up to 16 lines of voice.
2.3 E1 Interface
1-way E1 channel is provided by selecting a resistance of 75Ω or 120Ω75Ω by DIP switch
2 Q9 interfaces;120Ω resistance: 1 RJ45 interface.
Chapter Three Introduction to Centralized Frame
3.1 Frame Front Panel Descriptioz
Note: There are 15 slots on the frame totally, two of which are for power source and the rest 13 slots are for voice function cards and optical fiber transmission cards.
3.1.Optical Fiber Transmission Card
In order to facilitate the maintenance and installation, the optical fiber transmission card is fixed on the 0th slot and only one optical fiber transmission card can be configured on one frame. Each optical fiber transmission card can provide one-way optical transmission port and two-way Ethernet interfaces sharing 100M bandwidth.
3.2 Voice Function Card
One frame can be inserted with up to 12 voice function card, corresponding to Slot “1~12”; each voice card can provide 16 lines of voice with 192 line voice interfaces maximally when it is fully inserted. Classified by the using status, there are two types of voice cards available: FXO and FXS.
3.3 E1 Function Card
One frame can be inserted with up to 12 E1 function cards, corresponding to Slot “1~12”; each E1 function card can provide 1-way transparent 2M interface.
3.4 Power Card
The user can insert power card into the frame according to actual configuration.
There are two types of power cards: 220V and –48V, with two powers consumption of 200W and 300W (optional), and hot stand-by capability.
