I d like to build a power line communication card.i was exploring AFE031.
I have a analog communication interface that employs a 4 wire analog communication interface that transmits/receivies Plain Tones via telephone lines.
I d like such that the same analog interface card should be able to select whether to use the telephone wires or Power Lines for communication as the transmission media.
In such a case what will be the simplest solution to achieve the same?
1.if im using telephone wires i will be using 4 wire standard interface.
2.if im using power line communication interface then
Can the same 4wire/2wire interface can be used to communicate to another Power line Card (say for eg employing AFE031).I ve seen a two wire interface in the same..Can i use it?
or shall i use the decoded signals in the digital domain in the analog card and shall employ some digital communication standard to communicate with the AFE031 in the power line communication card?
Thanks for any help
It should be possible to select between the two methods...it is probably best if you send to me a block diagram of the network showing your proposed 4 wire and 2 wire schemes. Also when using PLC over the 2 wires what other voltages/signal will be present on those 2 wires? Do you have any data rate requriements for the PLC and are you restricted to a particular range of carrier frequencies on the PLC? Can you think of any coexistence concerns or coexistence requirements when operating over the 2 wire and 4 wire schemes simultaneously...i.e. do they both operate at the same time or always separate times?

Hello Mullins Ed,
we are building a Plc modem with afe031 and f28069. We a wondering that how to config the modem for a radial network (one master, multiple slaves). Is this in the data frame that we define the ip of each slave ?
Secondly, what does TI means the Data concentrator ?
With my best regards,
Hello Anh-Tuan Phun,
My apologies for the delay in the reply; I am checking with our systems team to answer your radial network question.
You can find more about our data concentrator solutions at: http://www.ti.com/lit/ml/slyt431a/slyt431a.pdf
You can set a device to master or device by configuring it via host messages. Please, refer to the attached message sequence for G3. With F28069, G3 can be configured as mini-DC (supporting up to 30 nodes) or device. For PRIME, it can be run as service node (slave) only on F28069. You will need our SGI platform to run as master node (Data concentrator). Using SGI platform for G3 or PRIME DC will allow you to support up to 1000 nodes.
The Data concentrator means master.

thank you for your response. Because we are at the beginning of the development so that some questions may be very stupid. I am wondering that using G3 or PRIME, we must only concentrate on the content that have to be transfered. What happen with we want to develop a software that allow users to manage their system using PLC. For example we develop a smart home management system. How to config this with G3 or Prime.
Have you found a sollution to this? Just a heads up: if you are developing for applications in Europe you have to operate within CENELEC B/C/D and not A. Prime is only able to operate within band A.
I noticed you have been communicating with one of our applications engineers from the systems team regarding a software question and source code availability for our TMDSPLCKIT-V3. Is this question related to that conversation? Could you please elaborate on this forum question? I do not fully understand it.
I am really sorry for the confusion, I see that I have accidentally posted this one here. This was meant to be at another thread.
Hi TI Employee
Can I use TI's PLC solution for DC power line or cold wire (no AC power, no DC power)? How high of data rate could I use for the distance of 5km?
Thank you for your help.
Hello Bin Rua,
TI's PLC solution can be used on AC power lines as well as DC power lines.
The achievable data rate is heavily dependent on the channel conditions. For the 5km line you mentioned, do you know the characteristics of the noise present on the line? Also, do you know how much attenuation will such line introduce on the PLC signal?
The paper “Developing robust power line communications (PLC) with G3” has a comparison on the maximum data rates available for different communication standards typically used in utility metering applications.
G3 and PRIME standards are supported on our TI Power Line Modem Developer's Kit (TMDSPLCKIT-V3): http://www.ti.com/tool/tmdsplckit-v3
Please do not hesitate to contact me if you have any further questions.
