Serial Packet structure for PBX

Dears. we developed a speech-enabled auto-attendant and want to
integrate it with any PBX using serial connection. for this reason we
need to know the packet structure of each PBX. Any PBX sends
information via its serial port, i.e. it sends packets of data
describing which operation is happening now. We can receive these
serial packets by connecting serial cable between the PBX and a
computer.
Each PBX has its own packet structure that contains the start and end
of the packet, the operation code, caller ext and receiver extension.
Hence, to handle any PBX serial packets, we need to know its
structure(operation codes, starting characters, ending
characters,....).

Examples of Ericsson PBX packets structure:

Start of packet: 0x02
End of packet: 0x0D0A
Operation code: 80, 81, 83, 84, 85, 91, 92, 94, 95, 89, 98, 54, 86
caller ext: 235
receiver ext: 312

02 38 30 32 35 33 33 31 32 0d 0a // Diverted call
02 38 31 32 35 33 33 31 32 0d 0a // Direct internal call
02 38 33 32 35 33 32 35 33 33 31 32 0d 0a // Diverted internal call
02 38 34 33 31 32 0d 0a // Direct external call
02 38 35 32 35 33 33 31 32 0d 0a // Diverted external call
02 39 31 32 35 33 32 35 33 33 31 32 0d 0a // Diverted internal call on
no answer
02 39 32 32 35 33 32 35 33 33 31 32 0d 0a // Diverted internal call on
busy
02 39 34 32 35 33 33 31 32 0d 0a // Diverted external call on no answer
02 39 35 32 35 33 33 31 32 0d 0a // Diverted external call on busy
02 38 39 33 31 32 0d 0a // End of call
02 39 30 38 0d 0a // Heart beat
02 35 34 0d 0a // Message light request update
02 38 36 32 35 33 33 31 32 0d 0a // Operator call

I really appreciate your help to get the packets structures of some of
the PBXs as Siemens, Nortel, Cisco, Alcatel, Mitel, NEC, Panasonic,
Aavaya etc.

many thanks



Re: Serial Packet structure for PBX


Both Ericsson and NEC use a proprietary serial protocol. Ericsson is called
MD110 and NEC is called MCI.

MOST others use an open standard protocol called SMDI.

I think I have a copy of all of them around here somewhere but I have to
review licensing first.

Re: Serial Packet structure for PBX


It just came to me that we may have been talking about two different things
here.

I THINK you are talking about what is called CDR (Call Detail Report) data.
I was talking about the different formats of integration type data available
by these PBXs.

Clear up for me exactly what you are looking for to make sure I can still
help.

Hi

Sorry to sayit but you are a bit late in the case of Mitel, They have had a
Speech enabled platform for approx 5 years now, Fully intergrated with the
system using IP.  Most info from the Mitel is now IP including the event log
, SMDR, etc.
Before using IP Mitel used fibre for it HCI intrface.

Re: Serial Packet structure for PBX


our speech-enabled system supports the Arabic language. I don't think
that any of the PBX manufacturers supports this language. maybe you are
right for other langauges.
