As allways thanks for all the help on the Forum.Installed a system today cannot get the BPTU card to synch with the 30 channel PRI from our local supplyer. Aked them to put the CFC on and it seemed better question been what is CFC and can we on the programing switch it on and off on the Toshiba and what should we say to the supplyer on or off for the Toshiba.Normaly if all the lights are off on the BPTU and the synch light is flashing the line is up and working even after they put on the CFC my Synch light is flashing good sign but there is one light on Yalam/RAI see it means RAI is not receiving again not sure what this means but i cannot get the line to work can any one help please?

30 channel PRI ???

Sorry in our country we get what we call a mega line and yes it has 30 channels you can have 30 incomming outgoing calls at a time hope i am explaining it correctly

We also have the 30 channel PRI in the UK and Australia or a E1 its also known as.

Have you done a ISDN trace using the TTY cable attached to the BPTU card?
Did you set it as ETSI?
Did you tick channel 16 in the "B channel" program? (should be 1-15 and 17-31)

By the way Hi Neil it is Carl here in Sunny Aus

Nice to here from you Carl hopfully same Carl we tryed ones to connect two PABX up a long time back.I normaly do not get problems with the PRI have not tryed the trace yet else then set to ETSI and you cannot tick 16 so have 1-15 and 17-31 ticked would just like to know a little more about CRC and the YALM/RAI light sure if i can get that one off the line will come up thanks to everyone for the help

Have you tried a loop back cable sending the Tx to the Rx pairs and vice versa.
This will send out the leds on the card and the errors should go out as well.
Obviously you wont be able to make a call but it should put out all the leds

Thank you still think there is something on the suppler side will takkle it again in the morning
