I am trying to gather clocking from a framed T1 and redistribute it to all SIP's / SPA's within a 7600's. Currently I have (2) 7600-SIP-200 with multiple SPA-4XCT3/DS0 with the network-clock setup to use the built in stratum 3 on each SIP.
I have read the below document, but am looking to verify a couple things. http://www.cisco.com/en/US/products/hw/routers/ps368/products_configuration_ example09186a0080b2135f.shtml It seems the SPA-8XCHT1/E can take BITS timing and redistribute it to the backplane, but the SPA-4XCT3/DS0 can't recover clock from the backplane. So does that mean (1) SPA-8XCHT1/E1 would be required per SIP-200 to provide clocking to the (3) other SPA-4XCT3/DS0 SPA's on the same SIP? So the SPA-8XCHT1/E1 wouldn't take clocking and distributing it to all the SIP's/SPA's in the same chassis? If that is the case then what is recommended? SONET clocking isn't really an option since the router only does channelized DS3 and we have plenty of devices that can distribute stratum 2 BITS.
