MDR-2000 VJ User's Reference Manual
Data Collection
Chapter 3
DATA COLLECTION
The purpose
of
this section
is
to describe the data collection process as well as the contents and
format
of
the data used by the MDR-2000.
3.1
CDR Data Collection
This section describes the details
of
call detail record collection on the MDR-2000.
It
covers the
conversion
of
PBX CDR records
to
Expanded MDR Standard Format, the available data selection
options, and the data translation defaults that are used.
Information on the Expanded MDR Standard Format is provided to assist in downstream process-
ing applications.
All data is collected from the PBXs over a 300 to 19200 Baud, RS232-C compatible port. This is
generally achieved by requesting the PBX supplier to enable the port on the PBX. In general, the
PBX CDR port must be configured for a standalone hardcopy terminal. T.hat is how the MDR-
2000 looks to the PBX.

3.1.1 Input/Output Records
A variety
of
PBXs are supported by the MDR-2000 and new ones are added to the list as required.
Each individual PBX requires a custom ROM (Read-Only Memory) chip for that PBX generic.
The differences that exist between ROM versions is entirely limited to the translation software.
The translation software is that component
of
the MDR-2000 that converts PBX specific data into
the Expanded
MDR
Standard Format CDR records.
Each record sent from the PBX
is
terminated by, or preceded by, a carriage-return/linefeed pair, and
one or more
of
the following characters; NUL, DEL,
DCl
, DC2, or DC3. These special characters
are ignored, the carriage-return is required.
