Unprecedented 1-RU Aggregation Capabilities
The Cisco ONS 15305 is the first 1-RU device that has high-density aggregation capabilities. Up to 189 E1, 18 E3/T3, or 16 STM-1
connections can be aggregated in a single chassis, with 1 slot left available for an optical uplink. Twenty-four RJ-45 ports for 10/100 Ethernet
traffic can be configured in a single chassis and aggregated onto an STM-n optical or a Gigabit Ethernet link. The Cisco ONS 15305 also
permits aggregation of up to 42 virtual container groups (VCGs) carrying Ethernet traffic from a multiservice-over-SDH access network.
Aggregated Ethernet traffic can be handed off an 802.1q trunk. This allows unprecedented efficiency in high-density concentration of Metro
Ethernet services for handoff to an IP backbone, or to a Cisco ONS 15454 ML-Series Resilient Packet Ring (RPR), as shown in Figure 5.
