DXC-240 Digital Crossing Connector

DXC-240 is equipment with the crossing connections of the time slots of E1. Three groups of exchange modules, each module provides non-blocking exchange between time slots of 8 E1, Totally the exchange of time slots of 24 E1 are provided. This equipment is adaptable to communications networking of mobile stations, electrical and financial departments, and also for the cases with shrinkage of the time slot of E1 as signaling monitoring of the telecom network and the value-added services.

Features of the system
Provide 24 interfaces with the impedance of 75Ω/120Ωfor users.
　> Flexible time slot crossing
　Embedded 3 groups of 256×256 crossing matrix, whole crossing connections of time slots of 8 E1 in each group are realized for the best utilization of the resources. Totally time slot exchanging of 24 E1 are provided.
　> Flexible networking
　This equipment could be used for kinds of networkings due to its flexible time slot crossing capability. Typical applications are for those cases like rental of E1 circuits and the shrinkage of E1.
　> Standard E1 interface, comply with ITU-T G.703, G.704 suggestions
　　Bit rate: 2048Kbps±50ppm
　　Line Code type: HDB3
　　Impedance of the interface: 75Ωimbalanced/120Ωbalanced
　> The system may lock the system clock according to the synchronization of the external digital trunk E1.
　> Jump connection of high impedance mode will not affect the signals of the circuit.
　> Download configuration data in the remote end
　When point to point applied or networking, DXC-240 in the remote end may download the configuration information of the time slot crossingly connected. The downloaded configuration information can be saved in the chip of the equipment; restart will be unnecessary even during the power failure. The channels for the download do not occupy the time slot.
　> Running, administration, maintenance and setting
　Administration and maintenance on the equipment in local and the remote end can be made through the background administration software. The graphical interfaces in Chinese are direct and easy to operate. The administration software can carry out the setting and enquiry on running status, clock mode, synchronization of CRC-4 of any link of E1 and the crossing of the time slots among the E1 circuits respectively.
　> The working power supply of the equipment is -48V ,allowable fluctuation of the voltage is -36V～-72V, total power consumption＜25W
　>l Compact-sized, light-weight, beautiful appearance, convenient installation.

　　　　　　　　　　　　Frame of the system

Typical applications
> Optimization of the mobile transmission network
> Transmission of the computer data
> Inner connections of the network
> Transmission of the graphs and other data services
> Monitoring of the No.7 signaling
> Value-added services based on signaling monitor
