Prisma IP M-Series
 
 
 
 
Application Examples 
 
Private Line TDM Transport 
The Prisma IP M-Series provides complete support for legacy TDM interfaces such as T1 or E1 voice.  Prisma IP 
transports T1/E1 services with complete Stratum synchronization and extremely low latency and jitter, for toll-
quality voice services.  This technique pioneers the transmission of synchronous services over an asynchronous, 
variable-length packet ring.  Complete support for standard testing functions such as loop-back and BER is 
provided.  Point-and-click provisioning and per-port management are provided for rapid service provisioning and 
performance monitoring. 
 
 
 
Metro Ethernet Transport 
The Prisma IP M-Series is optimized for IP and Ethernet transport and 
provides Layer 2/3 support for switching and routing.  Aggregation of 
multiple Ethernet services via Gigabit Ethernet and 10/100 interfaces 
provides carriers with efficient, high-bandwidth LAN to WAN 
interconnect services.  Bandwidth provisioning in 64 Kbps increments 
is provided for all ports including 10, 100 and 1000 Mbps Ethernet.  
Flexible provisioning enables fractional Ethernet services that can be 
aggregated and delivered in wire model or routed applications.  
Classification of packets per DiffServ is provided for up to three 
different classes. 
 
 
 
 
 
 
 Virtual LAN Services 
Another powerful application of Prisma IP is in the deployment of 
Virtual LAN Services.  Prisma IP supports Layer 3 routing and 
Layer 2 switching, including MPLS interconnect to core routers.  
Aggregation and de-aggregation of services is accomplished via 
MPLS, static IP forwarding, or dynamic routing.  Forwarding of 
packets can be based on Layer 2 addresses, MPLS labels, or 
Layer 3 IP addresses.  For Ethernet services, aggregation and de-
aggregation can be provided via Ethernet MAC address as well as 
the IP address or MPLS label.  DiffServ is also mapped into MPLS 
labels for prioritization and differentiation of services.  The Prisma 
IP M-Series can serve as both MPLS Label Edge Router (LER) or 
Label Switch Router (LSR).
