I have a E1-PRI connection between a Cisco 2621XM with a E1 Controller and a Hipath3750. The controller e1 and the Serial interface (interface Serial1/0:15) are up, but when I type the command: show interface Serial1/0/0:15, it shows "interface Serial1/0:15 is up, line protocol is up (spoofing)" and i don't know what "spoofing" means. The "show isdn status" command shows AWAITING_ESTABLISHMENT so the isdn protocol isn't up.
I debuged with "debug isdn q921" and the console shows "ISDN Se1/0:15 Q921: User TX -> SABMEp sapi=0 tei=0" many times but the router doesn't receive any answer from the HiPath.
if I connect the E1 PRI of the HiPath to a E1-PRI from the PSTN it works
Re: PRI connextion: line protocol is up (spoofing)
Paolo, Thanks for your answer
The "show controller e1" command doesn't show alarms and neither the "show interfaces serial 1/0:15" command. the cabling is ok because when connecting the E1-PRI of the Siemens directly to the PSTN, it works, so that makes me think that the configuration of the Siemens is ok. Something strange is the word "spoofing" in the output of the "show interfaces serial 1/0:15" command. Do you think it is related with the problem i have?
I want the E1-PRI of the router to act as the PSTN side. that's why I configured the "clock source internal" and the "isdn protocol-emulate network" commands in the E1 Controller and in the serial 1/0:15 interfaces, Do you think it is correct? Can the E1-Pri of the router act as the PSTN side?
I send you the output you ask for:
sh controlle e1
E1 1/0 is up.
