| Difference between 4100 and 5100 Found this thread: »Have both SS 5100a and SS 4100, which is better to use?
Where Doctor Olds states that newer is better, i.e. one should choose the 4100 over the 5100.
(Could not reply to the old thread, apparently it was too old....)
As the reason he states better support for newer DSL standards. But as far as I can see, these standards that are supported in the newer 4100 is also supported in the 5100 (G.lite and full-rate ADSL, ADSL2, ADSL2+ and RE-ADSL).
See the specs for the 5100: »subscriber.communications.siemen···00.shtml
Or is it as simple as the SBC/AT&T version being crippled on these? | |

Geneva, IL | Re: Difference between 4100 and 5100 I think the 4100 and 5100b use a newer better chip set than the 5100a. I'm not aware of any important functional difference between the 5100b (SBC version) and the 4100 (SBC version). | |

I'm not aware of any important functional difference between the 5100b (SBC version) and the 4100 (SBC version). Correct. The 5100b and the 4100 (SBC versions) use the AR7 chipset while the 5100a uses the obsolete AR5 chipset.
You can test the actual units if you have a 5100b and a 4100 (SBC versions) to work with. It will tell you in Telnet what modes are actually supported.
The command is:
The options returned could include these.
mult
ansi
dmt
lite
dsl2
auto
ds2p
red2
naam
emt
For example a 6520 Wireless Gateway returns this output:
cfg dsl{mode
: mode = auto [mult,ansi,dmt,lite,dsl2,auto,ds2p,red2,naam,emt]
My 5100 Router with the AR5 chipset shows:
login: admin
password:
User logged in
xsh> cfg dsl{mode
mode = mult [mult,ansi,dmt,lite,emt]

The answer I posted is factually correct for the 5100a and the 5100a does not support those extra standards.
Where do you see the specs for the SBC 5100a? Both the chipset and the firmware is crippled.

1 edit | Re: Difference between 4100 and 5100 Was never doubting you facts Doctor Olds. You have been a great help to me and lots of other people in here for a long time!
I just now realise that the original thread was for the 5100a, and I have the 5100B. So, then again (rephrased), what is the difference between the 5100B and the 4100, and which one is the preferred choice (SBC versions)?
Did not know that it was crippled in HW, thought it was FW only, guess they made a cheaper version of it then.... | |

Frisco, TX | Ok, have the 5100B, but not the 4100 yet (will arrive in the mail in a couple of days from AT&T).
So as far as I understand, it really does not matter, these are basically the same modem.
Thanks for the help/info! | |

| Re: Difference between 4100 and 5100 If you are provisioned for ADSL2 or ADSL2+ it very well could matter as no one has posted the modes a SBC 5100b supports for checking/validation. The 5100b hardware (AR7 chipset) may support it, but the SBC firmware may not explaining why the 5100 (all versions) is obsoleted and not available from SBC/AT&T or even Siemens anymore.
You would then only be able to use the 4100 to connect as it does support ADSL2 and ADSL2+ in Firmware and Hardware.

I was unsucessful at guessing the login/password combo to get pass the login prompt. I included the telnet statement on the chance someone would come up with the correct info for the login prompt.

1 edit | Wayjac, Doctor Olds,
the 2 last posts was exactly what I neded to get this working.
This is the message Gabriel Strongs application for password reset gave me:
"Packet sent but not received".
This is what the SBC 5100B reports:
"SpeedStream Telnet Server
login: 123
password:
User logged in
xsh> cfg dsl{mode
mode = mult [mult,ansi,dmt,lite,dsl2,auto,ds2p,red2,emt]
xsh>"
Getting Telnet to work on the SBC 5100B required a factory reset, just like Wayjac reported.
So, Doctor Olds, does this mean it supports the same standards as the 4100? | |

So, Doctor Olds, does this mean it supports the same standards as the 4100? What does the 4100 Telnet response show? You have to compare the 5100b modes to a 4100 modes (SBC versions) by the output to see if the units are identical or not.
Like I posted:

| Well, I do not have the SBC 4100 yet (as stated earlier), it probably arrives in the mail in a couple of days. Signed up for AT&T DSL earlier in the week. Will report back when I get it.
By the way, what is the NAAM standard that you have on your modem? | |

You may be thinking of the 6520 I used as an example, but I don't own one, it was from another post and I used it as an example in my post. I don't know what it means. The ones I know are listed below.

dmt = G.DMT [Std ADSL]
lite = G.Lite [Splitter-less ADSL]
dsl2 = ADSL2

1 edit | Re: Difference between 4100 and 5100 So where can we find a CLI manual/summary for the 5100b/4100 modems? At least, something to give us a hint what some of the commands do before actually running them. I've explored many of them, but there are some that I've avoided for fear of messing up the firmware.
Can the cfg command be used to configure settings or does it only list settings? I answered my own question.  | |

There is also SNMP info available once you have telnet/FTP access to these modems. | |

1 edit | OK! These are the commands to "permanently" assign a logon/password to the AT&T 4100 after you have entered it with a temporary login/password from the SpeedStream 5200 FTP program.
cfg upro#0{usr{un="logon"
cfg upro#0{usr{pw="password"
cfg upro#0{usr{per=0xffffffff
cfg save
do reboot
I can't say if any other upro# will work because I didn't try. The modem responds to the cfg save with a note that the settings are written to NVRAM.
Alternately the commands can be written as
cfg upro#0{usr{un="logon",pw="password",per=0xffffffff
cfg save
do reboot
If you don't like the settings you've changed, a hard reset apparently erases them all and restores the standard AT&T settings as does the command:
do defcfg
A command that you don't want to use is "do mfgdef" which makes the modem inaccessible on the 192.168.0.1 IP and (I'm guessing here) may restore an alternate configuration?
What info can you get out at the CLI that isn't available in the GUI? Well, "show dsl log" gives the following info:
17 seconds into current interval of 900 seconds
Time TxCrcErr TxFecErr RxCrcErr RxFecErr Los Sef LosSec SefSec ErrSec RxBlk TxBlk SNR Atten

Last hour 2 34 5 0 0 0 0 0 0 106164 106165 - -
xsh>
Edit: ... and there is a problem. Once you make a PPPoE connection even when using "PPP on computer" mode, you then are locked out of telnet access which requires a hard reset which loses the "permanent" login/password and all other configuration changes. ... uhh! | |

2 edits | Re: Difference between 4100 and 5100 Strange as it works different on the Retail Firmware units and the 3 hidden upro# (User Profiles) are only available in Telnet or by Serial connections.
These are the three (3) hidden User Profiles in the 5x00/4x00 series.
upro#0
upro#1
upro#2
Then in the Retail Firmware units it shows the unhidden User Profiles that start at #3 internally, but show up as #0 to #5 on the Web Interface for a total of 8 User Profiles.

| Re: Difference between 4100 and 5100 Actually, unless I missed something, that's exactly the way it works on retail devices as well.
The hidden profiles can also be set so they show on the user profile page. Of course you do have to enable them to show from a Telnet session. The following is true for all profiles.
cfg upro#0{nl=[y/n] Profile won't/will appear in the login menu.
cfg upro#0{ne=[y/n] Profile won't/will appear in profile wizard page.
In later firmware there are actually up to 5 hidden profiles upro#0-4. | |
