NEC NWA-078620 TRP-23G-1E SUB HI tributary card for SDH/SONET transmission systems.

The NEC NWA-078620 is a TRP-23G-1E SUB HI tributary card designed for use in NEC optical transmission and SDH/SONET multiplexing equipment. This card provides high-speed tributary interfaces for aggregating lower-rate signals onto higher-capacity transport networks.

Tributary cards of this type are essential components in telecommunications carrier networks, enabling service providers to consolidate multiple data streams for efficient long-haul transmission. The TRP-23G designation indicates support for 2.3 Gbps-class tributary rates, commonly used in legacy SDH and SONET deployments.

This is a legacy NEC transmission product from their established optical networking portfolio. While these systems have been superseded by newer packet-optical platforms, they remain in active service across many carrier and enterprise networks worldwide, creating ongoing demand for replacement and expansion cards.
