Sample config for an 877 on a US Verizon DSL link

Unanswered Question
Dec 7th, 2007

Hi, I'm working with some engineers in the US who are trying to configure an 877 and connect it to a Verizon provided DSL link. Configs supplied from the UK dont work on this unit, has anyone got a basic template they could use for this?

The problem I'm sure is down to the VPI/VCI and encapsulation types, no one seems to be able to state what should be used.

Hi Andy, How are you?

I cam across the Verizon DSL VPI/VCI setting a while ago with someone else - the setting should be:

Verizon 0/35

Hope it helps...

Hi Jay,

I'm well, trust you are also. Thanks for the information, the enginner in the US managed to get this working after 2 days of fiddling about, for some reason they were unable to sort out the encapsulation type.
