Migrating to a packet transport network
Leveraging its universal, open architecture, the 1850 TSS-100 allows operators to migrate their transport networks from all-circuit to all-packet. It integrates a full set of SONET features to support traditional transport-network architec- tures and to interwork with a large, existing installed base of equipment.
In addition, the platform supports transport packet switching, such as packet Operations, Administration, Maintenance and Provisioning (OAM&P), and integrated G.709 Optical Transport Hierarchy (OTH) trunk cards. The 1850 TSS-100 provides a cost-effective solution for implementing resilient metro and aggregation networks. This solution uniquely transitions from TDM/circuit to packet transport by smoothly migrating toward the delivery of packet-based services, maximizing return on investment over the network lifecycle.
The 1850 TSS offers Fast Ethernet (FE) and Gigabit Ethernet (GigE) interfaces for interconnecting with customer equipment or operator access equipment, deliv- ering carrier-class circuit and packet services. It also sup- ports stacked unidirectional path-switched rings (UPSRs) and bidirectional line-switched rings (BLSRs), with non- blocking aggregation and TDM traffic switching, or Layer 2 Switched Ethernet. These features offer cost-effective solutions for implementing resilient metro and aggregation networks and switched Ethernet-to-Ethernet.
