Overview
The CISCO 15454-CE-1000-4 is a networking module designed for integration with Cisco ONS 15454 SONET and Cisco ONS 15454 SDH ML-Series Cards, offering a seamless solution for extending Ethernet services over SONET/SDH networks. This module is equipped with four Gigabit Ethernet ports, facilitating high-speed data transmission and enabling efficient mapping of Ethernet frames into the SONET/SDH payload through packet-over-SONET/SDH (POS) encapsulation.
One of the key features of the CISCO 15454-CE-1000-4 is its support for daisy chaining Ethernet ports, allowing for the straightforward expansion of network connectivity. The device ensures the forwarding of unmodified valid Ethernet frames over the SONET/SDH network, ensuring data integrity and reliability. It supports jumbo frames up to 10004 bytes, catering to the needs of networks that require the transmission of large data packets without fragmentation.
Flow control is managed via IEEE 802.3x standards, with both symmetric and asymmetric types supported, ensuring smooth data transmission by preventing packet loss and network congestion. The protocol type supported is Layer 3, allowing for intelligent routing of data packets across the network.
Buffer management is a critical aspect of the CISCO 15454-CE-1000-4, with watermark (buffer size) settings available in default, low latency, and custom configurations. These settings help in optimizing the performance of the network by managing the threshold levels for high and low watermarks, which are set at 485 and 25 units respectively for the default configuration, and at 10 and 5 units for the low latency configuration.
The module also offers robust remote monitoring support, ensuring network administrators can efficiently manage and troubleshoot the network. It includes four POS ports, adhering to ITU-T G.707 and Telcordia GR-253 standards, which further enhances its capability in delivering high-quality Ethernet over SONET/SDH services.
Additional features of the CISCO 15454-CE-1000-4 include:
- Support for flexible Virtual Concatenation Groups (VCAT) and fixed Virtual Concatenation Groups (VCGs), enabling optimized bandwidth utilization.
- Fiber routing options for VCAT include common fiber and split fiber, with a maximum tolerable VCAT split fiber routing differential delay of 120 ms (Approx), ensuring high tolerance for network delays.
- Comprehensive split fiber routing protection types, including path protection, Two-Fiber Bidirectional Line Switched Ring (BLSR), Four-Fiber BLSR, and Linear Switching (1+1), guaranteeing network resilience and reliability.
- The module supports a maximum frame size in CTC of 1548 bytes, accommodating the needs of networks that handle large amounts of data.
Loopback capabilities, both terminal and facility types, are integrated into the device, facilitating easy diagnostics and network troubleshooting. The CISCO 15454-CE-1000-4 is an advanced solution for networks requiring reliable, high-speed Ethernet connectivity over SONET/SDH infrastructures, offering scalability, efficient data management, and robust protection features to meet the demands of modern networking environments.
