			PXS 540
			2.1 Brief description(s):
			The PXS 540 is a new class of network element. The 'Photonic
			Service Switch' intgerates data plane switching across a fast
			switching photonic fabric (POS, GE, SONET/SDH), and the control
			plane with GMPLS extensions.
			The PXS 540 can be deployed as a classical MPLS LSR, Broadband TDM
			crossconect (BXC), and/or an opaque Optical crossconnect
			(OXC). With service integration or any combination of functions
			can also be configured such as BXC+OXC, MPLS LSR+OXC, MPLS+BXC or
			MPLS LSR+BXC+OXC.

			The PXS 540 delivers flexible intra AS switched services. The PXS
			540 services large aggregation and/or metro core/regional
			applications such as STS-1 grooming, switched SONET/SDH, OCn
			optical services, Ethernet virtual leased lines, MPLS label
			switching, cable and/or DSL trunking.
			The PXS 540 delivers an integrated overlay (hybrid) or peer
			networking architecture for switched services for the wavelength
			core.Topology discovery, and layer 3 route interworking are
			provided with IGPs such as IS-IS and OSPF. Traffic Engineering is
