For management of STM-1 and STM-4 signals
The Alcatel 1664 SM Synchronous Add-Drop Multiplexer is an STM-16 system for transmission and add/drop of STM-1 and STM-4 signals.
The tributaries can be 140/155 Mbit/s electrical, optical STM-1 and optical STM-4. Up to 8+1 (spare) 140 Mbit/s or STM-1 tributary units or up to 4 STM-4 tributary can be housed in the 1664 SM. Any mix of the above tributary units is possible in the same shelf.
The system can be configured as Line Terminal Equipment, or as Add-Drop Multiplexer in both protected and unprotected configurations for transmission on standard and dispersion shifted fibers.
