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

View : 481
Type : Rack mount size
Description :

This is a point to multi-point device developed by our company, based on the E1 line transmission special super scale integrated circuit.


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.


32 Channel Telephone Multiplexer With SNMP


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.
