Goal
	Create a uniform earthquake data acquistion, analysis, and archiving 
	system in NC - the NCISN

Definitions
	PER - post-event review is off-line analysis, generally within 24-72 hours
	QR - quick-review as immediate event for alarms, generally within 10-20 min

Model
	1) Two RT systems - primary and backup.
	    a)  Long-term configuration:
		- one RT located at MP, one located at UCB.
		- both systems perform full event processing.
	    b)  Current configuration:
		- two RT systems, each with components at MP and UCB.
		- both systems perform full event processing.

	2) One archive at the NCEDC
		- possibly replicated at SCEDC or other places

Proposal

	1) NCEDC is the primary source of post-event review for both waveforms and parametric data

	2) Local RT is a fallback of PER if NCEDC unavailable (rules tbd on how then migrates to NCEDC)

	3) QR goes on in local RT system

Questions/Issues to be resolved:

	Requires rapid transfer of data (waveform and parametric) from each RT system to NCEDC
	-- both primary and secondary systems provide parametric data
		-- push - or pull ?
		-- granularity of transactions ?
	-- several possible models for waveforms:
		-- neither MP or UCB has complete view now.
		-- form complete view by: all push, all pull or some combo?
		-- allow for replacement of unQC'd waveforms by QC'd waveforms.

	Does not require RT and archive dbms systems to be identical:
		-- Requires information mapping if the dbms schemas are not identical.
		-- may require modifications to dbms schemas to accomodate mapping.

	MP and UCB now have a joint catalog and can share in responsibility for analyzing events
