SMDR record format

[Guest_imported]

Does anyone have the SMDR record format(s) for Nortel PBX systems? And the COM port settings?

There is a complete NTP book on CDR. There are two formats - Old and New. Most systems use the old format.
Here is the old format:


N 001 00 DN4999 A000009 7.1.02.1 06/28 10:15 00:00:20 9828124

N=Record Type (n=normal, s=Start, e=End)
001=Record number
00=Customer Number
DN4999=Originating ID (in this case ext 4999)
A000009=Terminating ID (in this case Answer supervised route 000 trunk member 009)
7.1.02.1=TN of Set (only appears if mutliple apearance DN)
06/28=date Stamp
10:15=Time Stamp
00:00:20=Call Duration
9828124=Digits Dialed and or outpulsed

As far as the TTY connection, use 7 bits, 1 stop bit, even or space parity. The Baud rate will depend on either the programming or dipswitch setting depending on the system and SDI Board type used.

By SMDR do you mean CDR? I wrote some BASIC code years ago to parse CDR records (I got tired of paying for MicroCall).

The COM ports on modern Nortel Meridian systems, with the exception of port 0 (zero), are set via LD 17 ADAN CHG TTY and so forth. Port 0 is often set via DIP switches on the CPU card (at least on option 11's they are).

A good default to try is

1200, Even, 7, 2.

Thanks a lot guys.
How can I get that a hold of this "complete NTP book on CDR".
Do you have access to a sample dump from SMDR so I can get a sample file via email? I need to write a program to read this stuff for as many PBXs as possible.

If you have the MERL (Meridian Electronic Reference Library) CD's that often come with the switches, it is under "System Management NTP's" with the document title "Call Detail Recording, Description and Formats"
You can also order Meridian document number 553-2631-100.
