Fiber optic multiplexer QX3440

digital

The QX3440 is a multiplexer with a 64 E1/T1 or 128 Mbps backplane for incoming and outgoing traffic. The high density concept gives it the capability to deliver a large number of voice and data circuits. The QX3440 is an E1/T1 DACS for the Telco infrastructure as well for the transport/utilities/energy networks which require a high number of analogue and data interfaces per node. The QX3440 is a non-blocking DACS for 64 E1/T1 interfaces or 1984 TS and will cross connect any voice or data interface. The system is designed with an automatic CAS fabric for voice on all slots. The QX3440 supports analogue voice (FXO to FXS, FXS to FXS in PLAR mode and E&M to E&M) and digital to analogue voice ( E1-CAS to FXS or E&M and E1-CAS to x E1-CAS). It can also be deployed as a channel bank with up to 120 or 144 voice channels from one or two 4 E1 / 4T1 copper or fiber optic modules. The QX3440 is used as an edge multiplexer or as an Add and Drop multiplexer in a ring, bus or nodal network with protection. CPU, cross-connect matrix, power supply and E1/T1 modules can be redundant if required.
