Hacking V2801F, TWCGPON657 & DFP-34X-2C2 to suite your ISP Fiber

> GPON market is a mess, plus explicit OMCI cause ONU Stick did not work

> Correction: `CI` not `C1`

# Triple Play Multiple ISP Problem, 4-port ONU Emulation
* Majority fiber vendor support multiple ISP
* ISP provide Triple Play service (Internet, VoIP & IPTV)
* Vendor supply 4-port ONU for each service or ISP

## Multiple ISP

## Multiple Service
![HG8240H5](Docs/Images/Ports%20Provisioning%20Multi%20Port%20Service.png)

Based on [ru-board](http://forum.ru-board.com/topic.cgi?forum=8&topic=80480&start=1360#2) **4-Port Emulation is limited**, not many xPON Stick can understand, only V2801F do support it, **because my Internet comes at Huawei HG8240H LAN Port 2** (LAN 1 for Main ISP, LAN 2 for 3rd party ISP)

In this table, list of xPON Stick that support 4-port ONU Emulation

> ✔️ Port Emulation Support |
> ❌ Not Supported

> `Root` mean your ONU is All in One where PPPoE/DHCP ended inside ONU (not bridge/route mode)

> I strongly recommend to get V2801F or CarlitoxxPro (Realtek), these xPON Stick support 4-port Emulation!
