Used Alcatel 1600 PDH/SDH telecoms equipment
Alcatel 1650 SMC STM-1/4 Optical Multi-Service Node
Alcatel 1650 SMC Optical Multi-Service Node is an ideal space-saving, next generation multi-service building block for local and metropolitan networks, providing unmatched performances for its room occupation.
Alcatel 1650 SMC features all standard PDH and SDH interfaces from 2Mbps to 622 Mbps and offers Integrated Service Adapter (ISA) modules specifically designed for ATM or Packet Ring switching and Ethernet or Gigabit Ethernet rate-adaptive transport through the optical network.
Alcatel 1651 SM 622 Mbit/s (STM4) Synchronous Add Drop Multiplexer
The Alcatel 1651 SM, Synchronous Acid-Drop Multiplexer, is part of Alcatel's family of products that comply with the synchronous digital hierarchy (SDH) defined in ITU-T recommendation G.707.
The 1651 SM is and STM-4 Add-Drop Multiplexer, i.e. is a transmission system able to drop/insert a wide range of miscellaneous tributaries from/into two 622 Mbit/s bidirectional synchronous streams sent in two directions, E and W.
The tributaries can be both plesiochronous and synchronous, electrical and optical.
The system can work as line terminal equipment, as line regenerator and Add-Drop Multiplexer, line protected or unprotected.
These are some of its main features:
- 2-34-45-140 Mbit/s plesiochronus tributaries. D/I capability up to 252x2 Mbit/s streams
- Fiber Optic VC extender to remotised Customer terminal (1631 Fox system).
- Synchronus STM 1 (155.250 Mbit/s) Electrical and optical tributaries.
- Line terminal and Add-Drop configurations unprotected or protected at Optical Line, Tributary and at common Part level.
- Wide optical interface choice
- STM-16 Upgrading capability
- Self healing protection schemes
- Wide range of cross connect features.
- Flexible tributary allocation inside STM-4 frame - VC4, VC3, VC12 grooming.
- Wide service channel availability
- Network management facilities.
- Working with OFA capability.
Alcatel 1660 SM - STM-64 Optical Multi-Service Node
The Alcatel 1660 SM is a capable multiservice provisioning platform (MSPP) with a 10 G capacity that builds next-generation multiservice SDH metro and regional transport networks. The Alcatel 1660 SM provides a single-shelf solution that integrates high-class transport functions — SDH cross-connect and CWDM add/drop functionality — together with carrierclass, Layer 2 packet/cell switching functions — Ethernet, MPLS, resilient packet ring (RPR), and ATM. With these capabilities, the Alcatel 1660 SM addresses metro and regional applications and offers a multiservice transport platform to support revenues from multiple broadband services such as:
- Triple play
- Private line and Ethernet virtual private LAN service (VPLS) business services
- Mobile aggregation
- Transport and lambda services
Alcatel 1664 SM 2488 Mbit/s (STM-16) Synchronous Add Drop Multiplexer
The Alcatel 1664 SM Synchronous Add-Drop Multiplexer, is part of Alcatel's family of products that comply with the synchronous digital hierarchy (SDH) defined in the relevant ITU-T Recommendations. The 1664 SM 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.
These are some of its features:
- 140 Mbit/s plesiochronous tributaries.
- Synchronous STM 1 (155.250 Mbit/s) Electrical and Optical tributaries.
- Synchronous STM 4 (622 Mbit/s) Optical tributaries.
- Line Terminal and Add-Drop configurations unprotected or protected both at Tributary and at Common Part level.
- Wide Optical Interface choice for transmission on G652, G653 and G654 fibers.
- Self-healing ring protection schemes: SNC-P at VC4 level. 2 Fiber and 4 Fiber Multiplex Section Shared Protection Rings (MSSPRINGs).
- Dual node ring interconnecting facility.
- VC4 cross connect features.
- Flexible tributary allocation inside STM-16 frame.
- Wide service channel availability.
- Network Management facilities.
- Integrated OFA capability.
