32Ch Telephone Mux | SNMP | Integrated 6U Rack-mount

This is a point to multi-point device developed by our company, based on the E1 line transmission special super scale integrated circuit. The slave end is a 6U rack, which can be plugged into 13 service cards. It also can plug in SNMP network management, realizing the SNMP integrated management.

Each multi-service fiber multiplexer card provides 32 telephone ports, 4 E1 ports, 4 FE ports, 2 GE ports, and 6 Ethernet electric ports which have independent bandwidth. The total bandwidth of 6 channels of Ethernet is 2400M, and each channel of the Ethernet signal is totally physically isolated. The device also provides 2 SFP slots for 1+1 optical backup. The internal circuit of the device adopts a fully digital circuit, with stable and reliable working, low power consumption, high integration, small size, and easy installation and maintenance.

●The total bandwidth of the integrated circuit fiber line based on independent intellectual property rights is 3.125G;

●6U 13-slots frame can be plugged in at most 13 multi-service cards; available for SNMP network management;

●E1interface complies with 703, adopts full digital clock recovery and smooth lock frame technology;

●4channels of 10/100M Ethernet, full/half duplex is totally self-adaptive. Each Ethernet electric port has independent 100M bandwidth physical isolation；

●2 channels of 10/100/1000MEthernet; full/half duplex is totally self-adaptive. Each channel has independent 1000M bandwidth physical isolation;

●100M and 1000M Ethernet support the transmission of VLAN super-long data packets, support use with the switch machine under IEEE802.1Q protocol, support the maximum packet length up to 10240 bytes;

●With Ethernet loop back protection function(when optical line loopback, Ethernet data will not be looped back, which protects from Ethernet clashes.

●32channels of voice access, support caller ID function/reverse polarity billing/fax function; telephone supported mutual dialing function of both side

●Voice port supports FXO/FXS/2 line audio/magnet telephone port, FXO port is connected to program switch, and FXS port is connected to user’s  telephone;

●The device with power failure detection function, can detect that the opposite end device port is off or optical fiber is not connected when optical signal loss;

●The transmission distance of the optical port is up to 80km, without relay; provide 1+1 optical port backup function to ensure the service is never interrupted;

●Various power options: AC220V、DC-48V, etc. Support dual power.
