960 Channel Telephone over Fiber Mux | 8U Intergrated Access Rack

This device is a point-to-point optical transmission equipment developed on the basis of the PCM fiber transmission dedicated ultra-large-scale integrated circuit developed by our company. The device is an 8U chassis, providing 1-960 telephones, 4 10/100M fast Ethernet interfaces (line speed 100M) or 4 10/100/1000M gigabit Ethernet interfaces (line speed 1000M) or 4 physical isolation 100M Ethernet interface (independent bandwidth of 100M per line speed); Interfaces such as RS232/485/422 asynchronous data/TTL signals, switching signals and other transmission channels can be extended, which is very flexible in application.

● Card-type design, easy to replace if there is a problem, avoid the problem that the whole device needs to be replaced if there is a problem with the 1-way telephone;

● Convenient expansion, just add a card, easy maintenance, just replace the card;

● The device is an 8U 19-inch chassis. It consists of a single optical port board and 16 60-channel telephone function boards. The optical port board provides 4 10/100/1000M Ethernet interfaces + one 1 + 1 optical interface + 2 expansions. Business interface model RS232/RS485/RS422, SNMP module, 4E1 interface, etc.;

● 60-channel voice card can also be replaced with 2 E1 cards, supporting up to 32 E1 receivers;

● The voice port supports FXO/FXS/2-line audio/magnet telephone interface, the FXO port is connected to the program-controlled switch, and the FXS port is connected to the user’s phone;

● 1-960 FXO/FXS access, support caller ID function/reverse polarity billing/fax function;

● The optional 4-way Ethernet interface is a switching interface and can also be divided into VLANs;

● Ethernet interface speed is 100M or Gigabit optional, full duplex/half duplex adaptive;

● With the function of viewing and displaying the working status of the remote device at the local end;

● The transmission distance without a relay can reach 2 ~ 100 kilometers;

● Multiple power supply options: AC220V, DC-48V, etc .; DC-48V power supply has automatic polarity detection function, no need to distinguish between positive and negative poles during installation;

● Telephone interface with lightning protection, anti-radar to GB/T17626.5 (IEC61000-4-5) short-circuit current wave 8/20μs, open-circuit peak output voltage 6KV standard.
