STM-1 Structured TDM NIM • The STDM NIM is intended to support applications requiring NxDS0 and CAS grooming and cross connections. It supports: • Unstructured Data Transfer (UDT) – Commonly known as: • Unstructured E1 • Unchannelized E1 • Structured Data Transfer (SDT) – Commonly known as: • Structured E1 • Channelized E1
STM-1 Structured TDM NIM • When the VT is configured for the Unstructured mode (unframed) , it will support the following connections: • Unstructured E1 – Full unframed E1 at 2.048Mbps • Fractional E1 (FE1) – The payload is Nx64K, but the transport across the PON from the SIM port to the STDM NIM VT is full E1 (2.048Mbps) • When the VT is configured for the Structured mode (E1 or E1 CRC), it will support the following connections: • Partial E1 (DS0) – The payload is Nx64K and the transport across the PON from the SIM port to the STDM NIM VT is Nx64K, plus ATM overhead
STM-1 Structured TDM NIM • The STDM NIM Service Partition can be provisioned to support: • No_Str - No Structured E1s – Will support 63 Unstructured or Fractional E1s • 32Str e1 - Up to 32 Structured E1s – Will support up to: • 32 Unstructured or Fractional E1s • Partial E1s (Nx64K connections) totaling 992 DS0s (32 E1s X 31 DS0s) • 63Str e1 - Up to 63 Structured E1s – Will support up to: • 32 Unstructured or Fractional E1s • Partial E1s (Nx64K connections) totaling 1953 DS0s (63 E1s X 31 DS0s)

Virtual Path (VP)SwitchingVsVirtual Connection (VC)Switching
ATM NIM ONT #1 STM-1 PON 1/37 ONT #2 1/275 4/62 7/152 ONT #3 ONT #4 VP Switching Versus VC SwitchingVC Switching • In VC Switching, each connection is switched through the network as a completely independent entity • This results in, potentially, hundreds or thousands of separate connections on the ATM interface • Each VC is assigned its own unique combination of Virtual Path Identifier (VPI) and Virtual Connection Identifier (VCI)
ATM NIM ONT #1 STM-1 PON ONT #2 1/37 VPI=1 1/275 1/62 1/152 ONT #3 ONT #4 VP Switching Versus VC SwitchingVP Switching • In VP Switching, a Path, or “pipe,” is created with a specific set of characteristics. This VP is assigned a specific VPI • Connections mapped to that ATM interface with the same VPI are “bundled” into that VP and are carried from point to point as a single connection • Each VC within the VP has a unique Virtual Connection Identifier (VCI)
ATM NIM ONT #1 STM-1 PON ONT #2 1/37 VPI=1 1/275 1/62 1/152 ONT #3 ONT #4 VP Switching Versus VC SwitchingVP Switching • Each VP is counted as only 1 connectionno matter how many VCs are in the VP • VP Switching is also known as VC Tunneling
VP Switching Versus VC SwitchingVC Switching • VP Switching and VC Switching occur in a logical switching environment between two ATM interfaces • In the Terawave PON environment, all ATM NIM cards perform VC Switching by default • VP or VC Switching is performed between the following cards: • ATM NIM to ATM NIM on the OLT • ATM NIM on the OLT to DS-3c SIM on the ONT • OC-3c and STM-1 ATM NIMs can perform VP Switching and VC Switching, but not both at the same time • OC-12c and STM-4c ATM NIMs can perform VP Switching and VC Switching at the same time
VP Switching Versus VC SwitchingWhy Is It Important To Know This? • There is a connection limit on each card in the network. This means that you can only make a certain number of connections across that card • This is normally not an issue, but under the right circumstances, this could be critical information • Those networks that use DS-3c SIM cards as the PON access point for DSLAMs fall in this category of circumstances
