Chapter 3 Turn Up a Node
• EXP ports are connected only to COM ports in between AD-xC or AD-xB cards that all belong to
the east side (that is, they are daisy-chained).
EXP ports are connected only to COM ports in between AD-xC or AD-xB cards that all belong to
•
the west side (that is, they are daisy-chained).
The EXP port of the last AD-xC or AD-xB card on the west side is connected to the EXP port of the
•
first AD-xC or AD-xB card on the east side.
The OPT-BST COM RX port is connected to the nearest (in slot position) AD-xC or AD-xB
•
COM TX port.
• The OPT-PRE COM TX port is connected to the nearest (in slot position) AD-xC or AD-xB
COM RX port.
If OADM cards are located in adjacent slots, the TCC2 card assumes they are connected in a
•
daisy-chain between the EXP ports and COM ports as noted previously.
The first west AD-xC or AD-xB card COM RX port is connected to the west OPT-PRE or
•
OSC-CSM COM TX port.
The first west AD-xC or AD-xB card COM TX port is connected to the west OPT-BST or
•
OSC-CSM COM RX port.
• The first east AD-xC or AD-xB card COM RX port is connected to the east OPT-PRE or
OSC-CSM COM TX port.
The first east AD-xC or AD-xB card COM TX port is connected to the east OPT-BST or
•
OSC-CSM RX port.
If a west OPT-PRE is present, the west OPT-BST or OSC-CSM COM TX port is connected to the
•
west OPT-PRE COM RX port.
If an east OPT-PRE is present, the east OPT-BST or OSC-CSM COM TX port is connected to the
•
east OPT-PRE COM RX port.
Step 3 Consult the following rules for OADM node add/drop path cabled connections:
• AD-xB add/drop (RX or TX) ports are only connected to the following ports:
An AD-xB add/drop band port is only connected to a 4MD card belonging to the same band.
•
For each specific AD-xB, the add and drop ports for that band card are connected to the COM TX
•
and COM RX ports of the same 4MD card.
The AD-xB and 4MD cards are located in the same side (the connected ports will all have the same
•
line direction).
Step 4 Consult the following rules for OADM node pass-through path cabled connections:
Pass-through connections are only established between add and drop ports on the same band or
•
channel and same line direction.
• Only connect AD-xC or AD-xB add/drop ports to other AD-xC or AD-xB add/drop ports (as
pass-through configurations).
An add (RX) port is only connected to a drop (TX) port.
•
Only connect 4MD client input/output ports to other 4MD client input/output ports.
•
• A west AD-xB drop (TX) port is connected to the corresponding west 4MD COM RX port.
• A west AD-xB add (RX) port is connected to the corresponding west 4MD COM TX port.
