Applications

The Cisco ONS 15305 8-Port 10/100 Ethernet Module can be installed in any Cisco ONS 15305

MSPP slot as part of the Cisco multiservice-over-SDH solution. The Cisco ONS 15305 can be

used as customer premises equipment (CPE) for medium-sized and large businesses to transport

traffic over an STM-1, STM-4, or STM-16 SDH uplink to the central office. In this use, the module

collects voice and data traffic from each site for switched voiced and data services, Layer 1 and

Layer 2 VPNs, and Internet access. The module gives the Cisco ONS 15305 the possibility

transporting Ethernet or Fast Ethernet traffic over the SDH network at up to the full line rates of the

LAN-10 or 100 Mbps. Using standard virtual concatenation, SDH bandwidth may also be efficiently

allocated at below line-rate speeds to meet each customer’s needs.

The Cisco ONS 15305 can also be deployed as a central office aggregator, consolidating traffic

from other Cisco ONS 15305 CPE, as well as directly connected customer TDM or data traffic from

electrical interfaces. The Cisco ONS 15305 8-Port 10/100 Ethernet Module can collect Ethernet

traffic from up to 14 SDH virtual containers, and hand off the aggregated packets to the Cisco ONS

15305 2-Port Gigabit Ethernet Module to which it is connected through the centralized Ethernet

crossbar. Traffic from different locations can be logically separated using IEEE 802.1Q-compliant

VLANs. The 2-Port Gigabit Ethernet module can then hand off a Gigabit Ethernet stream, or VLAN

trunk, to a colocated switch or router, to a Cisco ONS 15454 ML-Series, for increased packet-

intelligent transport over the core network. Figure 5 shows a diagram of this application.
