Hi guys, I have a problem with a configuration, I have a C3745, a E1 card used before and a new 12 Digital Modems. I need to configure these Digital modules but if I configure the serial X/X:15 with a ppp encapsulation, the serial protocol goes down!!!!, on the other hand if I configure the hdlc encapsulation, serial is OK. Some help, do i need to talk with my service provider about this?
Thanks a lot guys
