Configuration Example: Configuring SDH/Packet Services on Smart Line Boards

This section uses an example to describe how to configure SDH/packet services for smart line boards on the U2000.

Networking Diagram

This section describes the networking for hybrid SDH/packet service transmission.

Service Requirements

The service requirements for the network shown in Figure 3-47 are as follows:

  • Both User A1 and User A2 add/drop a GE data service. A bidirectional packet service whose VLAN ID is 100 is deployed between NE A and NE C, and is configured with tunnel automatic protection switching (APS).
  • Both User B1 and User B2 add/drop five E1 services. A bidirectional synchronous digital hierarchy (SDH) service is deployed between NE A and NE C, and is configured with linear multiplex section protection (LMSP).
Figure 3-47  Networking diagram

Board Layout
  • NE A is configured with an EM20 board for adding/dropping a packet service, an SP3D board to adding/dropping an SDH service, and an HUNS3 board to transmit services.
  • NE C is configured with an EG8 board for adding/dropping a packet service, a PQ1 board to adding/dropping an SDH service, and an HUNS3 board to transmit services.

Signal Flow of Services

This section describes the signal flows of SDH, and packet services that are transmitted in a hybrid manner.

Signal Flow of Packet Services
  • A PW-carried E-Line service is configured between NE A and NE C, whose VLAN ID is 100.
  • NE A: An EM20 board adds/drops services. Packet virtual ports 40001(V_ETH-1) and 40002(V_ETH-2) are configured on the HUNS3 board for transmitting packet data services.
  • NE C: An EG8 board adds/drops services. Packet virtual ports 40001(V_ETH-1) and 40002(V_ETH-2) are configured on the HUNS3 board for transmitting packet data services.

Plan virtual packet interfaces for NE A and NE C according to Table 3-241.

Table 3-241  Virtual packet interface plan
NE Virtual Packet Interface Mapped ODUk Bandwidth
NE A 40001(V_ETH-1) 1(IN1/OUT1):OCh:1-ODU3:1-ODU2:1 10GE
40002(V_ETH-2) 1(IN1/OUT1):OCh:1-ODU3:1-ODU2:2 10GE
NE C 40001(V_ETH-1) 1(IN1/OUT1):OCh:1-ODU3:1-ODU2:1 10GE
40002(V_ETH-2) 1(IN1/OUT1):OCh:1-ODU3:1-ODU2:2 10GE

Figure 3-48 shows the signal flows of services between NEs.

Figure 3-48  Signal flows of services between NEs

Signal Flow of SDH Services
  • An SDH service is configured between NE A and NE C. This service occupies the first to fifth VC-12 timeslots in the first VC-4 (namely, VC4-1:VC12:1-5) on the SDH link between NEA and NE C. This service is equal to 5xE1.
  • NE A: An SP3D board adds/drops services. SDH virtual ports 51(V_SDH-1) and 55(V_SDH-5) are configured on the HUNS3 board for transmitting SDH services.
  • NE C: A PQ1 board adds/drops services. SDH virtual ports 51(V_SDH-1) and 52(V_SDH-2) are configured on the HUNS3 board for transmitting SDH services.

Plan virtual SDH interfaces for NE A and NE C according to Table 3-242.

Table 3-242  Virtual SDH interface plan
NE Virtual SDH Interface Mapped ODUk Level
NE A 51(V_SDH-1) 1(IN1/OUT1):OCh:1-ODU3:1-ODU2:3 STM-64
55(V_SDH-5) 1(IN1/OUT1):OCh:1-ODU3:1-ODU2:4 STM-64
NE C 51(V_SDH-1) 1(IN1/OUT1):OCh:1-ODU3:1-ODU2:3 STM-64
52(V_SDH-2) 1(IN1/OUT1):OCh:1-ODU3:1-ODU2:4 STM-64

Figure 3-49 shows the signal flows of services between NEs.
