Numbering of the optical ports on the TOM board on the NMS
For all tributary boards, the logical ports are numbered starting from 3. In other words, the optical port numbers displayed on the NMS start from 3. Numbers 1 and 2 are reserved for WDM-side ports.

Relationship between the NM port and the active and standby system control boards of OSN9800
Switching between the active and standby system control boards does not affect the communication on the NM port.

Relationship between the NMS port and the active and standby system control boards on an OSN 9800
A switchover between the active and standby system control boards does not affect the communication of the NMS port.

Cascading relationship between ALM ports
ALMO1 and ALMO2 ports have the same definition, and they are used for output and cascading respectively. ALMO3 and ALMO4 ports have the same definition, and they are used for output and cascading respectively. For example, if the ALMO1 port is used to output alarm signals, the ALMO2 port can be used as an alarm/cascading port and be connected to an ALMO1 port in another subrack.

E6000 network port mapping
The on-board NICs of an E6000 are connected to switching planes A1 and A2. The E6000 provides two mezzanine slots (MEZZ 1 and MEZZ 2) for port expansion. The card in MEZZ 1 communicates with B1 and B2 switch modules, and the card in MEZZ 2 communicates with C1 and C2 switch modules.
