I recently got a VDSL->Ethernet converter. The model of the converter is Planet VC-231G. I wanted to share that when connected to the VDSL port on the BT Home Hub 5A, I can create a VDSL2 link between two devices. This allows to create a test environment to emulate a VDSL DSLAM. A second use case could be to transmit Ethernet over telephone wire using a single adapter (a router with openwrt as a second device is much cheaper than a second converter). I also have an older version of the VC-231 (100Mbps Ethernet only). Unfortunately, the router is unable to get synchronization with it. On the other hand, it is possible to create a link between VC-231 and VC-231G models.
I can confirm that, worked with Easybox 904 for me, I even managed to get a link through railway tracks at CCCamp2023 with it ;-]
Sadly it seems quite expensive at the usual suspects and only rarely appears in bearable prices.
I tried attaching it to ADSL modems and routers, but to no avail - sync would fail immediately, only VDSL2 CPEs worked for me.
Hello! Sorry for bringing up an old topic.... @Leo-PL could you please tell me what exactly you tried with easybox 904?
And @olek210 Did you just connected BT-Home with VC-231G as if it were a DSL supply from ISP, without any special configuration on BT-Home?
I have Planet VC-201A: still a few spares. They crash/die every once in a while (they are old), so I need a better replacement. After reading this thread, I pulled my speedport entry2, and tried to connect with VC-201A in CPE/CO mode, entry first as a modem-router, and then pure-modem, but none of the combinations worked.
I found two pieces of c4line 2-wire bridge C4L6400M-2wp, refurbished, about 21 Euro each, tried them out, and that seem to work, but such a good deal is rare.
It was a Planet VC-231G. Didn't have any other CO device to try, sadly. And it required a VDSL-capable CPE to function, would not work with ADSL-only stuff.
@Leo-PL thank you for your reply! So you set VC-231G in CPE mode, and connected with your easybox 904 with OpenWRT, using railway tracks as two wires, and it worked? How did you configure easybox?
Speedport entry2 is VDSL device. So I thought it might work. But it doesn't have Openwrt, so perhaps it won't, because I can't change the config beyond GUI....
No, I set it in CO mode. Easybox is the CPE here. As for its configuration, I only selected DSL standard and that was it - it worked. Of course I had the images prepared by @Zuzia
Could be a similar issue to Netsys NV-202, which only supports A43 carrier sets. Since the network of Deutsche Telekom only allows to use B43 and B43c, the Speedport probably doesn't support anything else.
Connecting a device running OpenWrt to the NV-202 works, as long as the carrier set is configured correctly (for VR9 modems, this requires using an Annex A DSL firmware).
I also have a Planet VC-231G, which doesn't have this issue. It has another compatibility issue, though: If G.INP is enabled, Lantiq modems aren't able to get a stable connection.
