Santa Clara, CA | more fusion switch questions 1. How long does the switch from a non ATT provider typically takes?
2. If the landline ATT number is never used, does it expedite switching to just ditch it and get a new number from sonic?
Will the service be installed on a new pair or will there be downtime?
3. Modem settings are not included in any faqs.
Is it bridged rfc1483 with LLC SNAP encapsulation?
4. Can the dslam be set to +20dBm for longer lines?

| It depends on the non-AT&T provider. If you are porting an existing number over, in some cases the port has to be done after the service is active and a new copper pair has to be used.
If it is an AT&T landline, it is much easier to keep the same number as the copper is just cut over to the Fusion service without the need to have a tech come out and change any wiring.
The modem just needs to be set to DHCP or bridged mode as you mentioned. We do not use PPPoE.
We can make a number of changes to the DSLAM to make your line stable and to provide you with as much speed as the line can handle.

ATT landline with dslextreme dsl. Do not really care what the number is. Ported or new, whichever makes the switch easier.
Strangely Sonic does not emphasize the elimination of dealing with ATT billing crooks, which other providers cannot do.

| said by public:So it still uses ATM encapsulation compatible with most adsl modems?
ADSL (all variants) transmit ATM cells between DSLAM and DSL modem. For dual-line Fusion the bonding is taking place at the ATM layer.
Fusion is ADLS2+ so for best performance you should use a DSL modem that supports ADSL2+. The Sonic Fusion DSLAM are backward compatible with ADSL2 and ADSL1, so they will work even with older DSL modems (but limited by the capabilities of the older protocols).

Reason for asking is because ATT is replacing atm dslams with ip dslams and modems need new firmware. |

| I'm pretty sure that the Sonic Fusion DSLAMs are IP DSLAMs as well (I think this was mentioned on an older discussion thread), but that only determines the backbone connection for the DSLAM. As long as the DSL line protocol is any form of ADSL (or even VDSL1) the DSLAM will encapsulate the IP packet into a series of ATM cells for transmission over the DSL line.
Only VDSL2 allows elimination of the ATM layer (less overhead).

it might not be just a matter of newer firmware for AT&T IP-DSLAMs

Eh? My AT&T billing is fine. |

Never cared about porting, since the ATT number has not been used.
Is there any drawback to completely cancelling everything ATT, and ordering sonic?
The non ATT is not voice, but shared line dsl currently broken. |

The sticky does not explain the difference.

From the discussion following it appears that AT&T is installing a client certificate in the DSL modem to ensure that only modems supplied by AT&T can be used with the service. The DSL modem is using the certificate to authenticate itself to the DSLAM.

For what it's worth... when I activated Fusion service at my new house (rental), the previous occupants didn't cancel their AT&T service. It took me a couple of days to realize that the reason why I couldn't get my DSL connection was that both AT&T and Sonic had active connections to the house. I had to go out and rewire the MPOE to get Sonic's lines.
So, it should be a new pair of copper and you can have them active simultaneously. |
