BT Direct Acces Lines (DALS)

[holt15]

Does anybody have any experience of the correct settings for a MM710 DS1 card to connect to a BT international DAL E1 circuit

We are getting conflicting information from our supplier and BT and I wondered if anybody else had them

The configs we have work but in one site in Hungary we have had to setup different to the rest of the circuits on that site and in the other sites

any help or advise gratefully accepted

I dont have the specific configuration for this service provider.Usually it requires three fields to be administered -add ds1,add signalling and add trunk.

It seems you are already aware and have working configuration in certain sites.Can you paste that config and tell me what error is seen when the same is used on this specific site?

Reconfirm ETSI Protocol with BT and CRC Settings to Yes.
