Hello,
I experience a strange phenomenon with a CISCO876-SEC/K9. The router is properly configured and works well with a (very old German) T-DSL access port (only 768kbps ADSL).
Now I connected the router to a "brand new" T-DSL subscriber line, a T-DSL 3000.
The router doesn't sync. The CD LED is blinking, and the DSL remains down. The technician tested the line with a dsl tester, and he said everything is OK with that line, it must be the router.
Now I am a bit lost - the router runs IOS 12.4.15T11(MD).
Should I downgrade to an earlier IOS, to make the router compatible to the German Telekom DSLAM(s)?
Should I apply the ADSL modem patch "Asymmetric Digital Subscriber Line (ADSL) Firmware", release 4.0.18?
But the descr. says that this patch is only meant for BT subscriber lines. So I don't really expect a change in behaviour.
Is there any one out there who has experiences with CISCO876 against current T-DSL 3000 lines and brand new Telekom DSLAMs?
Thanks a lot!
Best regards,
Olaf Jacobi
