| NYC/DirecTV Broadband Gateway reprogramming I'm trying to develop instructions for reprogramming Telocity/DirecTV modem for "any provider". I already have a few ideas, but need access to more modems to confirm that it works.
If you are in NYC area, and don't mind donating your modem to science (I will pick it up but I won't issue you a receipt  ), get back to alex@pilosoft.com
Also, if there are any DTV DSL customers with still-working service, I'd like to test a few things on your working modem, preferably on Sunday.
Please get back to me if you'd like to help, and let me know what kind of modem do you have ("brick"/X1/X2), and whether do you still have DTV DSL service.
I promise to share results here, if successful.
Thanks,
-alex (alex@pilosoft.com) | |

| Re: NYC/DirecTV Broadband Gateway reprogramming Much simpler.
When you boot it up with a serial port attached to it and a paper clip in a "reboot" position, it dumps all configuration traffic in/out, which should make it possible to create a new "configuration server" to imitate DTV.

| Re: NYC/DirecTV Broadband Gateway reprogramming When you paperclip to erase the configuration, the gateway will wait for you to enter your DSL phone number at »10.5.1.2/ and this is used to look up your account in Telocity's database (over HTTP), which redirects the gateway to a cache server, from which the gateway downloads its configuration (also over HTTP). Unless you're in VerizonEast (formerly BellAtlantic, not GTE) or Ameritech territory (and not going through WorldCom), the gateway will actually send out a DHCP request the first time it is powered up with no configuration, and get its IP (the IP for the WAN interface, which we call the "DSLIP", pronounced "D-slip"). It also gets the LAN subnet information, via a vendor-specific option in the DHCP protocol. Apparently the Nortel Shasta router figures out where the DHCP request is coming from (based on VPI/VCI/slot/port) and adds that information to the DHCP query before passing the query on to the DHCP server. The DHCP server is able to use that information to find your account and assign the gateway the correct IP information, but the gateway won't use this for routing until the configuration is downloaded.
Ameritech uses PPPoE which works completely differently, and VerizonEast uses aggregate routing so the Shasta can't figure out who you are until you enter your phone number (that's why you get a blinking red status light - that indicates a DHCP failure). When you enter the DSL#, that is added to the DHCP request, and the request is sent again. Once the gateway has the DSL# and IP information (from DHCP), it does the HTTP download to get its configuration, and never does a DHCP request again.
The tricky part about what you're thinking of is, the DHCP request and HTTP download happen on the WAN interface, meaning the DHCP and HTTP servers have to be on the other side of a DSL connection. I've heard it's possible to get two DSL modems to sync to each other on a dry copper pair, meaning you could get a standard DSL modem acting as an Ethernet bridge, and connect it to the DirecTV DSL gateway via a phone line, but I don't know if this actually works.
I hope this information is helpful! | |

| Re: NYC/DirecTV Broadband Gateway reprogramming You are absolutely correct as far as protocols, but I just want to make sure that the protocols are not different between "brick"/X1/X2.
Also, it is not possible to get sync on dry copper, DMT can't do that.
Again, I want to make a user-friendly way to reprogram the modems, for which I'd like to have access to all different modems... | |

| Is there a way I can statically assigned an IP Address to view »10.5.1.2/admin[?]- I don't want to install the direct tv software. I just want to access it directly from another machine via RJ45 or USB? It's not connected to my phone line anymore but I do have my password to access it. I just can't view the admin screen. I am missing something?
Is it:
10.5.1.2
255.255.255.0
10.5.1.1
Or is it:
255.255.255.252

| Re: NYC/DirecTV Broadband Gateway reprogramming Plug the modem into the NIC with a straight thru cable. Change the properties on the NIC to obtain IP address automatically. Reboot the computer. You should be able to surf to »10.5.1.2 if that's the right URL. I don't remember it. | |

@floca.alerondi | the subnet mask is 255.255.255.252
and the IP you will need to use is the gateway address which should be 10.5.1.2 | |

I'll pay 30$ cash to first 10 people in NYC with DTV DSL Broadband Gateway who get back to me today or tomorrow, and agree for modem pickup.
(Sorry, no mail, since the I need the modems by tomorrow)
Please get back to alex@pilosoft.com, and state what kind of modem do you have, and how you can be reached.

| Re: NYC/DirecTV Broadband Gateway reprogramming I could see loaning them, but not donating them. This is how I look at it: The reason someone might want to give you one is so that you can learn to reprogram the modems in general, thus giving them value after DirecTV folds. A fine goal. But if you succeed, then everyone who kept their modems gets the benefit, while those who donated lose it! Meanwhile, those who don't care whether the project succeeds or not -- and thus don't care if they get their modems back -- won't bother donating, because it's too much effort.
I think you'd get a better response if you promised to return the modems after testing. You probably can't guarantee you'll return them in working order, but that's OK. You can even ask people to include return postage when they send the modem if they want it back. I suspect that would work better than the $30 bounty. (After all, if this does work, then the modem is worth more than that.) | |

| Well, here's the thing:
You can't program the modem from CPE side. You can only program it from service provider side of the line.
I know enough about modem-gateway protocol to be able to program the modems. Since I run an ISP, I am able to do that (by running certain services on my side).
Unfortunately, at home you can't duplicate this, you need a cooperating provider... | |

| Re: NYC/DirecTV Broadband Gateway reprogramming r you sure you can not reprogram the modem on the CPE (sorry, don't know what CPE stands for but I have deduced that you are talking about the end-user side of the modem) any way at one time I had found a hack that allowed one to change the modem config so that I could move from USB to Ethernet after several calls to DTVDSL customer Dis-service produced little result. I appeared that all the modem's parameters could be changed from the web interface. Would you like me to dig up the output and information on my modem or would I be wasting your time?

All you got was the admin password for your modem, and the URL to the Admin functions page.
That allows you do do a few things such as switch the routed interface back and forth between USB, ethernet, or parallel (if your modem has that port), reboot the modem, and clear and re-download the configuration.
There is nothing in the available Admin function pages that allows arbitrary reprogramming of the modem.
And the password for your modem will not work with someone else's modem. | |

I am pretty sure without totally erasing and rebuilding the firmware/Software from nothing. You are wasting your time. I will give you a little hints. The X2 has 2 images of the firmware in the modem. Make sure you get them both erased otherwise the modem is programed to copy the second back to the first after it is erased.

| You missed the point. I'm not reprogramming new firmware into the modem. I'm creating a replica of DTV configuration server for ISP to run, so unaltered modems can pick up configuration.
If you can contribute more precise protocol description for HTTP-based config protocol, or a dump of HTTP traffic session from modem to gateway, it would be appreciated | |

Another thing to consider is if the modem side can be set to bridge mode without re-flashing the firmware. Currently the gateway gets one IP on the WAN side, then a .252 on the LAN side. In my case both sets are routable. I think they are/were the only ISP to do this.

| No, anyone selling RFC1483 routed service can do it this way. I have a .248 LAN behind a single WAN IP on my EF 5660 in RFC1483R mode.
What was a bit different with DTV is that they do this on RFC1483 bridged service, not routed service. That is to say, you can yank out their gateway, replace it with a bridge, and the result can be used to recover and use all four of the /30 IPs as well as the LAN IP if it's public.

| Re: NYC/DirecTV Broadband Gateway reprogramming It's /24 for WAN and /30 for LAN.
You may want to look thru the recent posts here. There was an ISP who, as part of their pitch to transition DTV customers, claimed they could re-use the DTV modems. However, they could not pull this off in the end, but supposedly managed to get inside them to some degree before deciding they were unsuitable.
Perhaps they will share notes with you. | |

| Potential problem...
My wife called the yesterday, and FedEx was waiting at the door with a pickup label from DirecTV DSL for an item worth $500.
I told her to send the FedEx guy away, since DTV didn't have the courtesy to let me know they were sending someone.
What a bunch of jerks, they just send out pickup labels without notifying anyone.
More importantly, the earlier posts saying they didn't want their stuff back appear to be in error. I have the original brick, circa 1/2000.
On another note, I checked my Discover online statement and saw that DTV charged me for another month of service on 1/03. I distinctly remember (and have the paperwork to prove it) that they pre-billed every month. Problem is... they shut off my service right before Christmas. The way I see it, they owe me about $12.
I tried to call them, but they will not take calls. I tried to click customer service, but it takes me to a login screen, and my old authentication information doesn't work.
I disputed the charge with Discover.
Check your statements!!! | |

It seems possible to me that one of the 2x5's could be a serial port, but I'm only going on the closeness between ten pins and the standard nine for pc serial ports. | |

| On which modem, X1 or X2?
On X1, the "Terminal" _is_ a serial port. (Wired with Mac standard pinout, just buy a "mac-to-serial" cable and you are good to go).
On X2, could be, but I don't have any X2s to play with just yet.
Point of note: You only need 3 pins to drive RS-232 minimally without handshaking (ground, txd,rxd). And X1 doesn't use handshaking. So it can be any of the 5-pin headers. | |

| The config file that all DTV modems download are just a bunch of text data. Within that is the vital IP info necessary.
If this data can be loaded onto the flash memory, and modified to reflect the new ISP info, then it shouldnt be hard to have a /24 on the WAN side and a private IP block on the LAN side.
Perhaps your best bet is to negotiate with DirecTV for the rights to the info .. then either buy up all the modems or provide a service to those that have them and want to re-use them.
These could, technically-speaking, all be just as powerful and flexible as your standard home-office routers. They could have requested them all back and sold them to a 3rd party for re-programming and resale. But really, most of these Gateways have been used by at least 2 customers during their life-span. So technically they'd have to be considered/labeled "Refurbished". | |
