Hello everyone,
I'm looking for working example: Out-of-Band Clocking or clock recovery in adaptive mode.
My problem is that I have configure both scenario on 7609S (ios 15.0(1)S2 )with:
7600-SIP-400 |
SPA-24CHT1-CE-ATM |
on both ends.
Configuration on routers I take from this manual:
http://www.cisco.com/en/US/products/hw/routers/ps368/module_installation_and_configuration_guides_chapter09186a00807f9ea0.html#wp1635929
and recovering don't work stabile.
In logs I have a lot of down/up statement:
041082: Feb 21 13:29:42.499 CET: %CLOCK_RECOVERY-4-CLOCK_FAILED: Recovered clock 0 on module 3/0 failed
041107: Feb 21 13:33:33.508 CET: %CLOCK_RECOVERY-6-CLOCK_ACTIVE: Recovered clock 0 on module 3/0 is now active
041114: Feb 21 13:37:54.506 CET: %CLOCK_RECOVERY-4-CLOCK_FAILED: Recovered clock 0 on module 3/0 failed
041115: Feb 21 13:39:34.503 CET: %CLOCK_RECOVERY-6-CLOCK_ACTIVE: Recovered clock 0 on module 3/0 is now active
041116: Feb 21 13:42:05.504 CET: %CLOCK_RECOVERY-4-CLOCK_FAILED: Recovered clock 0 on module 3/0 failed
and most of the time the recovered status is HOLDOVER:
Recovered clock status for subslot 3/0
----------------------------------------
Clock Mode Port CEM Status Frequency Offset(ppb)
ENHANCED PRIMARY 0 HOLDOVER 28
Summarizing if anybody has working example of OOB clock recovery please, please share it with me.
best regards
Piotr
