BBPCM multiplexer

Multi-operation access PCM30 opto-electrical equipment—BBPCM realizes the integrated access of various operations into one 2M interface. The equipment is suitable for the electric power system county transfer and 35KV electric power substation, public security 3/4 rank network and other small capacity multi-operation application. Meanwhile, it is also suitable for the unattendant machine room as well as locations where the 2M-channel is hired. The network management cab be configured as the RS232 interface outside the equipment, the E1 interface or the internal channel of the optical interface. It is convenient to realize the network management when the 2M-channle is hired.

BBPCM is able to be used in the county transfer of the electric power system and the communications between the 35KV electric power substations. Hired E1 channel is applicable in transmitting telephone signals, telemechanical signals, computer data, detection signals from unattendant stations, LAN and Internet information from the electric power substations to the county transfer stations and to realize the broadband transmission within one channel with BBPCM. The equipment is featured by the flexible configuration of the bandwidth that the Ethernet and V.35 occupy. When the number of telephone channels is limited, the bandwidth of Ethernet and V.35 signal may be expansive while it is narrow as the number of telephone channels is huge.

BBPCM is equipped with optical interface, which can be connected with fiber to complete the transmission of 30 channels of V.35 data, various voice telephone and Ethernet on the optical cable. The conversion configuration between the optical interface and E1 interface is able to be completed with one scrap.
