CDB4/11(1)

CDB4/11 is a type of ISDN splitting network component that has been widely used in a variety of communication fields. ISDN stands for Integrated Services Digital Network, and is a type of network that is used to transmit data rapidly over telephone lines. ISDN Networks are made up of two main components: a Central Office (CO) and a Data Center (DC). The CDB4/11 is an ISDN splitting network component that is used to split the signal that is sent from the CO to the DC.The CDB4/11 is used to provide a voice connection between the CO and the DC while also splitting the signal in order to ensure that the data that the CO is sending is transmitted to the DC without interference. This is accomplished by having two distinct "spines", each containing four pairs of optical fibers. The first spine is responsible for the transmission of voice data, while the second spine is responsible for the transmission of data.The working principle behind the CDB4/11 is relatively simple. The ISDN signal is sent from the CO to the CDB4/11 where it is split into two distinct signals. The voice signal is transmitted through the first spine, and the data signal is transmitted through the second spine. The signal is then sent from the CDB4/11 to the DC, at which point it is reassembled back into a single signal which is then sent to the CO.The CDB4/11 is a versatile piece of equipment that has a number of applications in the field of data transmission. It can be used to split the ISDN signal in order to ensure that the signal is sent without interference, and it can also be used to provide a voice connection between the CO and the DC. It is also used in the construction of ISDN networks, as the CDB4/11 serves as the central hub of the network.In summary, the CDB4/11 is an ISDN splitting network component that is used to split the signal sent from the CO to the DC, and to provide a voice connection between the CO and the DC. It has many applications in the field of data transmission, and is a crucial component in the construction of ISDN networks.
