CM-100 Packet Transport Switch
The CM-100 Packet Transport Switch is a carrier-class packet-optimized network element for the transport of Data and TDM services. It relies on MPLS and RPR for the creation of a lossless shared media, over which services are efficiently multiplexed with class-of-service guarantees, and provisioned using MPLS control plane technology.

Both data and TDM services are mapped into MPLS consistently with the IETF PWE3 WG mehods and procedures. This provides a universally-applicable encapsulation method, enabling full service convergence and efficient packat aggregation and transport of TDM and Data services, decoupling services from the physical facility. This in turn allows carriers to provision new data services instantly, without the need to physically allocate timeslots or fiber, recoupling lost revenue and reducing churns.

Data services can be provisioned over a number of Ethernet and TDM User Interface Modules (UIM). All services are unidirectionally characterized by user-defined CIR, PIR and CoS parameters.

All services can co-exist over the CM-100 Packet Transport Switch transport network, thus enabling a multi-service transport solution, providing the right infrastructure for enabling the following end-user applications:

• Ethernet Virtual Private Line
• L2 VPN (VPLS)
• Broadband access aggregation
• Triple Play services
• Distribution of multicast traffice such as IPTV
• Backhaul of 3G wireless traffic

The CM-100 product line consists of the two models having the same dimensions and providing the same functionality, only varying in the number user interface modules. The CM-106 supports up to six vertically-aligned UIM/HIM, whereas the CM-110 supports up to ten vertically-aligned UIM/HIM.

Both models support a number of TDM and Data User Interface Modules (UIM), Hub Interface Modules (HIM) and Ring Interface Modules (RIM). The UIM vary from DS1/E1 to DS3 (both channelized and clear channel) PDH rates, from OC-3/STM-1 to OC-48/STM-16 SONET/SDH rates, and from 10/100 FE to 1-10 GE. The GE and OC-48/STM-16 interface cards support two modes of operation: 1) as a tributary (UIM) and 2) as a Hub Interface Module (HIM). The HIM can be used to connect to other CM-100 RPR rings either directly or through an IP/MPLS or SONET/SDH network.
