  10. This card serves as the central controller for the complete STM-1/4 system Based on a powerful processor, Motorola PowerPC 860, supplemented by 64MB SDRAM and 128MB Flash Main OS is loaded on a 128MB compact flash disk The card can be optionally redundant ensuring that provisioning happens even when one PSS has failed The card is not traffic-affecting viz., traffic remains unaffected in spite of PSS failure(s) VCL100 STM-1/4 Processor Sub-System (PSS) Confidential Slide 10 Orion Telecom Networks Inc. 2003-2004

  11.

  13. VCL100 STM-1/4 uses an IP overlay over SDH overhead bytes to carry management information Uses standard Layer 3 routing protocol, OSPF for routing management information VCL100 STM-1/4 provides multiple communication channels for carrying management information D1 to D3 bytes (DCC-RS) D4 to D12 bytes (DCC-MS) F2/F3 path overhead bytes Ethernet to E1 mapping E1 management channel can be physically accessed using the 28xE1 tributary card VCL100 STM-1/4 VCL100 MSPP:Management Features Confidential Slide 13 Orion Telecom Networks Inc. 2003-2004

  14. In addition, the platform supports a DCC transparency feature allowing it to be deployed in mixed vendor scenarios eg., if the alien equipment uses D1-D3, VCL100 STM-1/4 can use D4-D12 with pass-through of D1-D3 bytes E1 mapping saves additional equipment and optical ports while introducing VCL100MC4 in incumbent networks with alien equipment Since connectivity between VCL100MC4 and the alien equipment can be through E1s rather than wasting additional STM-1 interfaces VCL100MC4 provides support for up to 12 In-Band Channels (IBC) and one E1 management channel The maximum data rate per node is 4 Mbps VCL100 STM-1/4 VCL100 MSPP:Management Features Confidential Slide 14 Orion Telecom Networks Inc. 2003-2004

The ETC (Ethernet Tributary Card) is a tributary module on VCL100 STM-1/4 The module supports eight 10/100 Base-TX ports with support for auto-negotiation An ETC can be operated in either of the following mapping modes for transport over SDH Ethernet over SDH mode: This involves the mapping of Ethernet traffic to multiples of VC-12s up to one STM-1 equivalent per card Compliant to recent ITU standards on Ethernet over SDH (EoS) Ethernet over PDH mode: This involves the mapping of Ethernet traffic to multiples of E1s using Multi-Link PPP Compliant to IETF rfc 1990 on ML-PPP and rfc 1662 on “PPP in HDLC-like framing” Also supports an option to directly map Ethernet traffic to E1s without further mapping to SDH for access router apps VCL100 STM-1/4 ETC solution on VCL100 STM-1/4 Confidential Slide 16 Orion Telecom Networks Inc. 2003-2004

  17. ETC supports the following Ethernet over SDH framing standards to enable inter-connection of Ethernet LANs over an SDH network: Ethernet over LAPS standard as per ITU-T X.86 Ethernet over PDH using ML-PPP/PPP/HDLC as per IETF rfc 1990 and rfc 1662 Ethernet over GFP as per ITU-T G.7041 in the frame-mapping mode ETC allows efficient mapping of “tagged” and “untagged” Ethernet traffic into SDH virtual containers It is possible to flexibly map data traffic arriving on any Ethernet port to one or multiples of VC-12s, VC-3s, VC-4s (n X VC-12s/VC-3s/VC-4) where n=1,2…63 for VC-12s, n=1,2,3 for VC-3s and n=1 for VC-4.

  18. The bandwidth allocated to a given port, in multiples of VC-12s, is software configurable It is possible to configure the ETC in Ethernet over SDH or Ethernet over PDH (ML-PPP) mode Ethernet over SDH: Either GFP or X.86 mode on a per-card basis ETC supports PAUSE frames as per IEEE 802.3x for flow control ETC supports port aggregation that enables aggregation of traffic from multiple source ports to the same exit port thus saving expensive ports on the destination router/switch Each ETC currently provides one STM-1 equivalent of upstream bandwidth.
