Table 18-3	ONS 15600 SDH Circuit Status
Status		Definition/Activity
CREATING		CTC is creating a circuit.
DISCOVERED		CTC created a circuit. All components are in place and a
		complete path exists from circuit source to destination.
DELETING		CTC is deleting a circuit.
PARTIAL		A CTC-created circuit is missing a connection or circuit
		span (network link), a complete path from source to
		destination(s) does not exist, or a MAC address change
		occurred on one of the circuit nodes and the circuit is in need
		of repair (in the ONS 15454, the MAC address resides on the
		alarm interface panel (AIP); in the ONS 15600 SDH, the
		MAC address resides on the backplane EEPROM).
		In CTC, circuits are represented using cross-connects and
		network spans. If a network span is missing from a circuit,
		the circuit status is PARTIAL. However, a PARTIAL status
		does not necessarily mean a circuit traffic failure has
		occurred, because traffic might flow on a protect path.
		Network spans are in one of two states: up or down. On CTC
		circuit and network maps, up spans appear as green lines,
		and down spans appear as gray lines. If a failure occurs on a
		network span during a CTC session, the span remains on the
		network map but its color changes to gray to indicate that the
		span is down. If you restart your CTC session while the
		failure is active, the new CTC session cannot discover the
		span and its span line does not appear on the network map.
		Subsequently, circuits routed on a network span that goes
		down appear as DISCOVERED during the current CTC
		session, but appear as PARTIAL to users who log in after the
		span failure.
DISCOVERED_TL1		A TL1-created circuit or a TL1-like, CTC-created circuit is
		complete. A complete path from source to destination(s)
		exists.
PARTIAL_TL1		A TL1-created circuit or a TL1-like, CTC-created circuit is
		missing a cross-connect or circuit span (network link), and a
		complete path from source to destination(s) does not exist.
CONVERSION_PENDING		An existing circuit in a topology upgrade is set to this status.
		The circuit returns to the DISCOVERED status when the
		topology upgrade is complete. For more information about
		topology upgrades, refer to the Cisco ONS 15600 SDH
		Reference Manual.
