Detailed Product Description

High density and convenient configuration: 1. FT-50B may be equipped with two optical interfaces; they are backed-up mutually
2. All function cards can be plugged in and pulled out on line. The function cards
are 2 optical transmission cards, one 4 E1 cards, and 2 access cards. The 4E1
card can be 75 ohms or 120 ohms. The access cards can be audio interface or data
interface. 10/100M Ethernet card can also be selected by user.
Powerful net management system: 1. User can read the states of the equipment remotely 2. The audio level and the data rate will be configured by NMS 3. As many as four NMS platforms will run in the same network, and they can be placed
in any node of the net
High reliability: The application of LSI FPGA circuits and advanced design technology makes the equipment
more steady. Optical transmission cards and power supply cards are all backed
up mutually. All function cards can be plugged or unplugged when the equipment
is in running state.
Convenient to configure: 1. Because all function cards are individually, so the user can configure the equipment
conveniently
2. Smart in shape 3. The application of aluminum alloy material makes the equipment more beautiful
and more light
