Charging block content


CHARGING BLOCK• CDRs are collected in RAM block

before storing on mass storing devices (e.g. hard disks)

• The amount of data stored on disks (tape) at one time

• 2-64kB• Contains complete charging

records

CHARGING DATA ON HARD DISKS

• CDRs are written on the disk files of the CHU

• The files are named CFxxxx.DAT, where xxxx is the ordinal number

• The ordinal number can range from 0001 to 9999

• The file size is selectable (e.g. 1MB)

• Contains complete charging blocks

Relationship between logical files and the VDS and CHU disks


Open File is in use and the data is being written into this file. Only one file is open at a time.

Full File is closed and waiting to be transferred.

Transferred File has been transferred to the remote side.It can be used again when needed.

Waiting File is waiting to be compressed.

Compressing File is being compressed.

Un-usable File is unusable because the physical hard disk is full.
