Question re TDA 30 and basic rate ISDN

[b106]

Hi All
Does the BRA ISDN have to be set at P-P or is it just required that the TDA matches the setting of the ISDN line
I have no dial tone for short periods on the 3 basic rates
I see a post from OBT with the settings as Permanent Permanent P-P and Fix 0
If the isdn circuits are P-MP must they be changed by the telco to P-P
Thanks In advance

you can set the system to match the ISDN settings, if point to multi point set layer 1 to call and layer 2 to call and tei to automatic

sometimes layer 1 works better set to permanent on the older systems, if the lines are set differently to the system it will cause having to pickup the line once or twice before getting dial-tone after the lines are not used for 5 - 10 minutes

The system is a TDA30 Ver 5
I will find out in the morning if the lines are P-P or P-MP
Thanks OBT
