I am a volunteer teacher trying to get my students fired up by learning Broadband. Accordingly I am building a small scale DSL/PPPoE Broadband network that they can touch, deconstruct and put back together themselves with a little help. Issue is, we have very little budget (I am paying for it personally). It needs to be physical to inspire them (we've tried simulation but the eyes glaze over)
So far we have a DSL modem (a DLink flashed with DD-WRT) and an IP DSLAM (ZTE ZXDSL 9806H) connected with a 50 pin amphenol connector.
What we now need is an upstream BRAS and a PPPoE Server. Given budget constraint I was hoping it might be possible to use a ERICSSON T720G MDU ONU (link removed because reputation too low) as the BRAS (doubling as a OLT for a future FTTx demo) for upstream traffic by connecting to the DSLAM on the upstream GPON interface
This would give us the following 'Broadband' architecture as shown in the picture:
Will this architecture work? Or do I need to shell out for some more equipment?
There is an error in the diagram. All traffic needs to go via the PPPoE server (Linux or not)
