The Cisco ® SPS service provider switches deliver cost-effective Metro Ethernet access solutions. These products are optimized for multitenant units (MTUs) and multidwelling units (MDUs) in which the service provider delivers triple-play (VoIP, video, and data) services to multiple businesses or homes in close proximity.
The Cisco SPS2024 24-Port 10/100/1000 Gigabit SP Switch (Figure 1) is ideal for environments in which security and uptime are important. It offers 24 Gigabit copper ports and 2 shared Small Form-Factor Pluggable (SFP) modules for optional optical interfaces for connecting to the core network.
The Cisco SPS switches facilitate the delivery of multiple services over a Layer 2 network with support for Q-in-Q stacking. This feature allows customer VLANs to be kept separate across the service provider backbone. Also, for efficient delivery of multicast traffic (such as video) to multiple customers, these switches provide support for a variation of Multicast VLAN Registration (MVR).
