PCM30U, PCM30U-OCH – User's, Operating and Maintenance Manual

  

 

 

The unit involves a real time clock and backed-up memory that makes it possible to record times of 

transmitted commands in the PBS unit. DORIS management system records command times in a database 
and allows for their filtering.  

The unit can be equipped with a display to show the number of received / transmitted commands by 

each command input / output, up to 999 commands. The command input / output to be displayed is selected 
using buttons on the unit’s front panel. 

 

E.1.2 Submodules 

The PBS unit supports the following sub-modules: 
a)  SB4E1 converting commands to full 2 Mbps E1 stream 
b)  OS1 converting commands to full 2/8 Mbps stream through optical cable (1310nm) 
c)  OS2 converting commands to full 2/8 Mbps stream through optical cable (1550nm) 
d)  SU64 converting commands to 64 kbps stream with codirectional interface 
e)  SUMO converting commands to slow RS232 channel to be transmitted via modem. 

 

The PWA subrack accommodates one PBS unit. PCM30U-OCH in the 6OCH4 rack can accommodate 

up to four PBS units, transmitting 10 to 40 commands and binary states from each network point. If 6OCH8 
rack is used, up to eight units can be installed allowing for the transmission of up to 80 commands. 

Configuration of PBS in PWA differs from configuration in 6OCHx, 3OCHx subracks, because in PBS in 

PWA incorporates some functions of central module. The differences are mentioned in chapter describing 
individual features.
