This packet optical transport (POT) platform supports any mix of traffic, from all-circuit to all-packet, with an up to 1.2Tb/s switching capacity fabric and 100 Gigabit Ethernet optical interfaces.

As part of a large 1850 TSS portfolio for POT networks, the TSS-320H supports a combination of transport technologies — including Carrier Ethernet, Multi-Protocol Label Switching-Transport Profile (MPLS-TP), wavelength division multiplexing (WDM) and TDM.

Two protected switching fabrics, each offering two options:

• 1.28Tb/s packet-based switching capacity or 320Gb/s HO SDH TDM switching capacity
• 800Gb/s packet-based switching capacity or 160Gb/s HO SDH TDM switching capacity
• 16 full slots (or 32 half slots) for I/O cards with the following traffic capability:
  • 8 full slots with 100Gb/s
  • 8 full slots with 60Gb/s
• All half slots with 10Gb/s
• Two protected controllers
• Two protected power supplies
• One fan tray with fully redundant fans
• Up to two subracks in a standard ETSI rack

• Up to 1.2Tb/s switching capacity, with unique, universal-switch architecture
  • Packet or circuit switching in their native format
  • SDH switching, including high order/low order (HO/LO) virtual circuit (VC) switching
  • Any traffic mix, from all-circuit to all-packet
• MEF Carrier Ethernet 2.0 standards-based, connection-oriented packet transport through MPLS-TP
  • Transport-oriented operations, administration and maintenance (OA&M) for Ethernet and MPLS-TP
  • Highly scalable linear and ring full-packet protection, allowing multiplefailure sub-50ms resiliency
• 1850 TSS single-NE, multi-shelf arrangements with drop shelves, offering optimized fan out for E1 circuits, as well as compact coarse or dense wavelength division multiplexing (C/DWDM) options, leveraging the Nokia 1662 Synchronous
• Multiplexer Compact, the Nokia 1646 Synchronous
• Multiplexer (SDH/PDH) and the Nokia 1830
• Versatile WDM Module (VWM) (photonic)
• Multiple synchronization options for transport networks:
  • SDH G.813 synchronization, including synch status message (SSM)
  • Synchronous Ethernet (SyncE) with SSM
  • Full interworking between TDM and data synchronization, including SSM messages for supporting timing redundancy
  • EEE 1588v2 for Time of Day (ToD)
• Secure management
  • User authentication
  • Encryption of management protocols
  • Security logs
