IDM 300GP telephone optical transmitter PDH Optical Multiplexer
IDM 300GP
Description
IDM 300GP telephone optical transmitter can provides two physical isolation speed 1000M Ethernet interfaces, 8 groups E1 of transparent transmission, provides FXO/FXS interface of a caller ID display, can provide 300 channels phone. IDM-300GP can support 14 groups disk, 1+1 backup power supply, 10 business plates, two main control units, all disk support hot plug.
Te narrow and broadband business of IDM 300GP can be multiplexed into the optical transmission channel. It can simply the transmission line and save the cost.
The device is inserted into a disc type structure design, each service plate is provided with 30 telephone calls, and the equipment is easy to install and convenient to maintain.
Product character
Optical rate is 2.5Gbps.
1 set of CMU control management center disc, ten trays of users, each user interface disk can access 30*64K audio telephone business, the largest user interface is 300 channels.
Provide 2*1000M (physical isolation) Ethernet ports
Provide 8 groups E1 interfaces, 4 groups E1 are 75Ohm unbalances type and other 4 groups E1 are 120Ohm balanced type.
The whole machine is a centralized machine frame design, standard 6U chassis, in accordance with the telecommunications and operational standards.
Equipment can be easy to install and maintenance is convenient.
