RY2000 type digital program-control exchange is that our co***ny introduces foreign advanced swapper, adopt International Telegraph and Telephone Advisory Committee (CCITT) G.712, recommendation, etc., symbol of G.732, standard develops the digital program-control exchange of a new generation produced. The management with very strong figure program-control exchange and official working function.
Range of application: The complete machine can make up more than ten thousand exchange systems from 16 linear upgrading , have abundant relaying interface and user interface, can as user grade, terminal station grade, remit and connect magnitude and end remit many kinds of exchangers, such as magnitude, etc.. This product can adapt to the digital communication environment and analogue communication environment , have already been used in telecommunications at all levels, the communication occasions of the railway, electricity, public security men, fire control, army, school, hotel, industrial and mining and enterprises and institutions extensively.
Developing direction: Pass the special-purpose digital interface , ISDN interface and system, finish the unitarily in many kinds of signals, such as pronunciation, data figure, dynamic picture, FAX, etc. or mutual transmission, really realize multimedia communication.
Exchanger structure: The exchanger adopts the strata to insert the structure of modes in Chinese operatic music, dilatation is convenient, flexible.
Exchanger capacity: User's quantity: 16-10240, 16 doors increase progressively
The quantity of relaying: 16-2048, 16 increase progressively
Characteristics:
Large scale integrated circuit design: Systematic hardware adopt 16 or 32 microprocessor and super large-scale communication special-purpose integrated circuit with the characteristics of the modern techniques and high integration.
Advanced craft: Adopt international advanced sticking to welding and full-automatic crest solder technology; the production technology reaches the international leadin |
