Alcatel-Luc ent 1850 TSS -100 6
Migrating to a packet transport networkLeveraging 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 ser vices,
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.
