# Hacking RTL9601C1
Hacking V2801F & TWCGPON657 to suite your ISP Fiber

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

## With my issue:
* [V2801F](https://www.amazon.com/Universal-Stick-Address-Supported-Attention/dp/B08C818JSQ)
  * Support n-Port ONU Emulation
  * Support OMCI explicit provision **override** `OMCI_FAKE_OK 1`
  * Good Firmware, support many ISP (Global)
  * Build not strudy
* [TWCGPON657](https://item.taobao.com/item.htm?spm=a1z09.2.0.0.c0552e8d7UBYLF&id=597031866488)
  * **Not Support** n-Port ONU Emulation
  * **Not Support** OMCI explicit provision **override**
  * Bad Firmware, limited ISP
  * Silm & Tight build

## 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

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

> ✔️ Port Emulation Support |
> ❌ No Support

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)

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

## Same Chipset, Different Vendor
* There are many RTL9601C1 out there, not all firmware are interchangable
* V2801F cannot use TWCGPON657 firmware
* DFP-34X-2C2 (Realtek) cannot use V2801F firmware
* TWCGPON657 **can use** V2801F firmware
