I have a PRI/2CE1u card in a 2620. I have been having a lot of trouble getting it to work with an aggregate bearer (10 x leased lines on one interface). BT inssist the line is ok and I am pretty sure my config is ok. My understanding of the 'Local Alarm' LED on the controller means that no line is connected. Any thoughts? I am using a 'cab-e1-db15' cable to connect to the x21 NTU. But I have my suspicions that BT have terminated on the BNC (but claim it is on the x21). Please help if you know anything this job has gone on long enough.
