We support Nortel Optera/TN products including:
The Nortel TN16X (STM-16) transports up to 16 STM-1 signals.
Network applications for this NE are point-to-point, Add/Drop Chain, Multiplex Section Shared Protection Ring, and Regenerator.
Interface types for the TN-16X include STM-1 and STM-4 optical; 140M, STM-1 and 34M electrical. Matched-node connections provide path switching protection for STM-1 and STM-4 optical interfaces.
The Nortel TN1X provides 2 Mbit/s to 155 Mbit/s terminal multiplexing, add/drop, ring and cross-connectivity features. Optical and electrical STM-1 tributaries may be employed for the provision of STM-1 spurs to customer sites or for interconnection of clusters of multiplexers.
The Nortel TN1C is an add/drop multiplexer (ADM) that multiplexes tributary plesiochronous signals to an STM-1 signal, supporting flexible tributary unit (TU) assignment and selectable interfaces (2 Mbit/s interfaces and in one variant a 34/45 Mbit/s tributary).
The Nortel TN4X Network Element is an STM-4 multiplexer for use as a ring head in STM-4 local network rings, or as an STM-4 ring node in core network applications.
The TN-4X can also be configured as a low capacity cross-connect for use primarily at the local/regional network boundary. The TN-4X supports a wide range of plesiochronous and synchronous interfaces.
The TN-4XE network element is Nortel’s enhanced STM-4 multiplexer, designed to support high port density.
This TN-4XEE can operate as a terminal, add-drop multiplexer, hub multiplexer, extension shelf or regenerator.
The TN-4XE supports the a wide range of connection types from simple through connections to complex 4 way ring to ring connections.
The Nortel TN64X ADM transports up to 64 STM-1 signals.
Network applications for this NE are Multiplex Section Shared Protection Ring and Regenerator. The TN-64X is designed to provide high capacity, survivable transmission in the National and Regional networks.
The TN-64X ADM NE supports optical tributaries such as (up to four) protected STM-16 tributaries, (up to eight) protected STM-4 tributaries and a combination of both.
