  Multi-service access PCM30 optic-electrical equipment--BBPCM30 realizes the integrated   access of various operations into one 2M interface. Multi-service E1 channel is application in  transmitting the telephone signal, RS232,RS422/485 data, NX64K V.35 data, 10/100Base-T data, and so on.
   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. 
  
  • BBPCM is equipped with optical interface
  • Transmitting Nx64k V.35 signal and Nx64k Ethernet signal simultaneously 




 　
　

      Summary  

Appearance

 　





•  The front panel connected to the main shelf with magnetic button can be easily opened. And the interface cards and other unit cards all support hot swap and replacement which make it convenient for maintenance, extension and upgrade.

Reliability
Design

 　
• 
   1. All kinds of interface cards and unit cards inside the equipment are able to be   hot           swapped and replaced.

       2.Each working circuit has its own power supply and recoverable fuse so that any error happening on single unit will not affect others.

       3.The most outstanding feature of V.35 interface is timing mode, which can be configured as DCE  or DTE

　
　 　 　 　 　 　 　 　 　 　 　 　 　
　

Application

 　


  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-service application. Meanwhile, it is also suitable for the unattendant machine room as well as locations where the 2M-channel is hired.
 BBPCM can 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 no-man stations
