Nokia/Alcatel 3AL94207EC 1626LM TRBD1121
Descriptions
- TRBD: Tributary Board.
- Functional Designation: TRBD1121
- Manufacturer: Alcatel-Lucent (now part of Nokia).
- Port Density: 21 x E1/T1 ports.
- Primary Part Number: 3AL94207EC (The unique identifier for ordering and inventory).
- Product Family: 1626LM (The platform it is designed for).
- 1121: The subtype code, where "21" almost certainly denotes the 21-port density of the card.
- Form Factor: A plug-in module that occupies a single slot in a 1626 LM chassis (e.g., 1626 LM XC or XT).
- Management: Configured and monitored via the 1626 LM's management system, either locally or through a central network manager like Alcatel's 1350 NM.
Core Function Platform
- Platform: This card is a Tributary Board (TRBD) designed for the Alcatel-Lucent 1626 Light Manager (LM). The 1626 LM is a compact, multi-service platform used for aggregating and transporting traffic over optical networks using SDH (Synchronous Digital Hierarchy) or SONET (Synchronous Optical Networking) standards.
- Primary Function: Its job is to provide the physical interface for up to 21 E1 (2.048 Mbps) or T1 (1.544 Mbps) copper lines. It aggregates these lower-speed "tributary" signals and multiplexes them into a higher-speed SDH/SONET stream (e.g., STM-1/OC-3) for transmission over the network's fiber optic backbone.
