The Cisco ML-MR-10 card offers important advantages in service provider network architectures,
supporting new, profitable services as well as simplifying service activation. Table 2 outlines some
of these capabilities.

flexibility
The Cisco ML-MR-10 card supports VLAN-ID translation. This capability allows the service
provider to change the ingress VLAN tags (802.1Q or 802.1Q in .1Q) to avoid VLAN collisions
within the network (resulting from the use of the same VLAN ID by different customers) and
translate them back at the egress of the network.

Network resiliency
Support for IEEE 802.17B RPR over SONET/SDH provides sub-50-ms recovery times for data
services, depending on the service offering.

Reduced interface costs
The use of the Cisco ML-Series cards and shared bandwidth transport allows the service provider
to benefit from statistically multiplexing the edge traffic before handing off a more efficiently filled
interface to the core router or switch.

Applications
The Cisco ML-MR-10 card provides the flexibility to meet the demands of a wide variety of network
applications found within many service providers’ transport networks. The following figures show a
few of the applications that can be cost-effectively deployed using the Cisco ONS 15454 with the
ML-MR-10 cards.
Ethernet Service Delivery
The Cisco ONS 15454 with ML-MR-10 cards can be used for any service delivery based on the
type of SFP module plugged into the Ethernet port. The platform supports 10/100/1000 BASE-T,
100BASE-FX/LX/BX, and 1000-BASE SX/LX/ZX. Customers can use the Cisco ML-MR-10 cards to
offer a wide range of Ethernet services with Layer 2 switching, RPR, and advanced QoS
capabilities.
