The QX3440-A 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-A 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-A 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-A 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-A 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.
Link protection is provided for different applications for small and large networks:
- MSP1+1 protection for each E1
- PDHUPSR ring Protection per E1 with a maximum 32 E1 rings.
- PDHSNCP Protection of TS, or 64Kbps protection for any voice/data/Ethernet flow
This DACS is available in 2 models using the same cards : the QX3440 5U and QX3440-S 2.5U.
