I have a saved eBay search that specifies this particular ECI B-FOCuS modem. It's obviously a case of "wait and see" . . . 

[asbokid]

flamey, a FTTC subscriber from Colchester, has posted some useful exterior pictures of the ECI to the Sky User forum  As flamey points out, it is very difficult to distinguish the ECI from the Huawei.  The LEDs and the sockets are spaced slightly differently on the ECI, but on purely physical appearance, they are otherwise virtually identical devices.

EDIT: 

@uklad:  did you find time to try the 'mount' hack?

Attached to this post is a "screen-scrape" from a BT Slide Presentation. It shows the Huawei and ECI modems side-by-side.

I did think i had seen that before..

Quick answer is No, unfortunatly training away for a week and being mad busy when i got back does not help, i should have some time tomorrow to play once the kids are in bed..

Hi uklad!

Did you get a chance to have another look?

Hi uklad!

cheers, a

I did and to be frank im out of my depth i dont know Linux well enough to get any conectivity out of it...

where are you located asbokid ?

[asbokid]

Aww! Don't give up!  you've already done all the hard work!

Attached is a silly bit of C code for the PC.  It converts any file into an octal dump.  The dump can be used in the Telnet Upload Trick.

The Trick allows any executable to be downloaded to a router or a modem using the -e escape character option of the echo command in the BusyBox ash shell. [1]

// The Telnet Upload Trick - asbokid 2012 <ballymunboy@gmail.com>
//
// How to download an arbitrary binary to an embedded device
//
// 1) convert the binary into an octal dump using the code below
// 2) paste the dump into a telnet shell or a serial console
// 3) chmod +x the dumped file (myscript.sh) and run it
// 4) the octal dump will be echoed into a binary file (mybinary)
// 5) chmod +x that new binary and run it

#include <stdio.h>

void main(int argc, char **argv) {
    FILE *fp;
    unsigned int c, d = 0;

    if(!(fp = fopen(argv[1], "rb"))) {
        fprintf(stderr, "can't open file %s\n", argv[1]);
        return;
    }
    while(1) {
        if((c = fgetc(fp)) == EOF)
            break;
        if(!(d++ % 0x10))
            fprintf(stdout, "echo -n -e ");
        fprintf(stdout, "\\\\%04o", c);
        if(!(d % 0x10))
            fprintf(stdout, " >> mybinary\n");
    }
    if (d % 0x10)
        fprintf(stdout, " >> mybinary\n");
    fclose(fp);
}

We can use the Trick to download any code we want to the ECI:  a telnet daemon, a tool to dump the decompressed forms of those tweaked files, or anything else..

Im not giving up, its more to do with Time Vs Ability, i have the ability just not the time, im sourcing a HG612 should be here in few days once its stable i can set the ECI in my office or even loan it to you to speed up development..

[asbokid]

Sounds good! Wasn't doubting your expertise!  Lots of people will be interested to see how the ECI performs against the Huawei on the same line.  cheers, a

[JoshShep]

Hi uklad, if you didn't end up getting a new modem I will sell you my Huawei HG612 for £20 including P&P? it's a rev b.

Got one thanks just installed it still seem to be getting full 40/10 at the moment will pull some stats later

[JoshShep]

From using both the ECI and huawei hg612, I have noticed that I get more jitter using the hg612. The eci seems to perform a little better on my connection. may be different for your connection.

[waltergmw]

@ All,

What a splendid reason for asking BT to allow them to be purchased on the open market.

Kind regards,
Walter

Josh -- A quick couple of questions for you. When you had your FTTC service installed, which VDSL2 modem was officially provided as the active CPE? The Huawei or the ECI? As you probably realise, Openreach supply the modem to match the DSLAM in the FTTC.

If your installation was a Huawei, I wonder from where did you obtain the ECI B-FOCuS modem? Care to share the information, please?
