Provides Service Providers with the ability to extend the reach of their OC-48 network
The new Cisco Optical Regenerator enables direct long-haul connectivity at OC-48line rates between Cisco 12000 series Gigabit Switch Routers (GSRs). This eliminates the cost of deploying a network of SONET/SDH equipment.
The Cisco Optical Regenerator is a bidirectional OC-48/STM-16 regenerator that supports single-mode optical fiber transmission when connected to an OC-48 line card (Packet-Over-SONET [POS] or Dynamic Packet Transport [DPT] based) in a Cisco 12000 GSR. It provides OC-48 line extensions in increments of up to 50 miles (80 km) between Cisco 12000. This new regenerator is the first IP-addressable optical regenerator with Cisco IOS (R) support. Customers can use the same command-line interface (CLI)-based network management platform for Cisco 12000 GSRs as well as for the Cisco Optical Regenerator.
The Optical Regenerator provides a standards-compliant SONET/SDH interface, enabling it to be used in networks transitioning from a SONET/SDH to an IP infrastructure. The optical regenerator supports complete optical-to-electrical-to-optical regeneration with a payload transmission delay of less than 20 usec.
It regenerates the Synchronous Payload Envelope (SPE) and line layer overhead, and terminates and generates the section layer overhead. The Optical Regenerator provides monitoring and insertion of both the B1 and C1 bytes. The Data Communication Channel (DCC) is utilized for management, enabling IP addressing and Simple Network Management Protocol (SNMP) access.
In compliance with GR-253, the optical regenerator will generate an L-AIS within 125us upon detecting a Loss of Signal (LOS) and Loss of Frame (LOF). The optical regenerator will also monitor for B1 parity errors and generate the appropriate alarms. The optical regenerator provides error counters for section-level performance parameters, Errored Seconds (ES), Severely Errored Seconds (SES), and more, which can be retrieved when notification is provided through a Threshold Crossing Alarm (TCA).
The Cisco Optical Regenerator supports through timing meeting Bellcore`s category II jitter transfer requirements. In addition a standby local oscillator is provided to allow communication during network failures.
The optical regenerator is easily manageable through SNMP. It utilizes the DCC channel to provide IP addressing. Cisco IOS software is also supported. Using either a console port or a 10BaseT Ethernet port, the Cisco IOS software CLI can be accessed for configuration capabilities. In addition, SNMP Management Information Bases (MIBs), RFC 1595, and RFC 1213 are also supported.
