8040 ADM8040 ADM

The 8040 is a SONET/SDH ADM-on-a-chip™ that operates as an OC-192/STM-64 SONET/SDH add-drop multiplexer with a full 40Gbps STS-1/STM-0 cross-connect.

• Full STS-1/STM-0 granular transport-level processing and non-blocking cross-connect (40G x 40G) with hitless grooming across all ports and all time slots (full TSI)
• On-chip connection memory for flexible, hitless configuration of working and protection configurations for each STS-1/STM-0
• Support for hairpinning, broadcast, multi-cast, drop-and-continue and full TSI

The 8040 has all of the functionality of a conventional SONET/SDH ADM system integrated onto a single device. It has a total of 10 ports, with 2 high-speed line interfaces running at OC-192/STM-64 and 8 low-speed add/drop ports that are software configurable to run at OC-3/STM-1, OC-12/STM-4 or OC-48/STM-16.  All 10 ports provide complete read/write access to section and line overhead, path trace access, pointer processing, alarm detection and insertion, and section, line, and path performance monitoring (PM). The 40Gbps STS-1/STM-0 cross-connect is provided across all interfaces.

• Two (2) 10Gbps high speed line ports, OC-192 (STM-64)
• Eight (8) low-speed tributary ports, independently software programmable to OC-3/12/48 (STM-1/4/16)
• Handles all concatenation levels of STS Mc, (2 < M < 192), e.g., 2c, 7c, 24c, and any valid mix of STS-1 and concatenated payloads, making it ideal for data over SONET applications
• Section/line termination/generation of all traffic on all 10 ports, with pointer processing and frame alignment on all ports
• Ability to force path AIS and UNEQ on any STS-1 under software control

In addition to fully compliant traditional SONET functionality, the 8040 has extra built-in features that enable next generation SONET features such as virtual rings, multi-ring termination and SONET mesh. The combination of standards support and new generation features allows systems to be deployed in a legacy environment and then upgraded to enable next generation features with only a software change.

Overhead Access:

• Support for automatic protection switching:
• K1/K2 byte access and BER monitoring
• Support for 1+1, 1:1, 1:N, UPSR, and BLSR protection mechanisms
• Flexible protection schemes
• Flexible Transport overhead byte extraction/insertion with dedicated interface to external overhead processor, on all ports. Provides for easy adaptation to changes in standards, as well as interoperability with existing proprietary equipment, with no hardware changes
• On-chip electric wavelength (overlay ring) support, including TOH byte forwarding and error condition preservation
• SONET/SDH compliant performance monitoring, condition and alarm reporting
• Path Monitoring on all incoming traffic per GR-1400-CORE (B3, C2, J1), with STS-1 granularity for paths

Standards Compliance:

• GR-253-CORE, SONET Transport Systems: Common Generic Criteria
• GR-496-CORE, SONET Add-Drop Multiplexer (SONET ADM) Generic Criteria
• GR-1230-CORE, BLSR
• GR-1400-CORE, UPSR
• ITU-T G.707: Network Node Interface for the Synchronous Digital Hierarchy
• ITU-T G.803: Architecture of Transport Networks Based on the Synchronous Digital Hierarchy
• ANSI T1.105

Applications:

• Next generation SONET/SDH terminal equipment (ADM)
• Metro digital cross connect systems
• SONET aggregation multiplexers
• Gigabit Ethernet transport multiplexers
• ADM-on-a-Blade for DWDM systems
• Stand-alone element in a single stage switching system (a.k.a. "pizza box")
• Support for multi-chip configurations for larger port count systems
