Number of client-side ports on the TTX board
There are 10 physical ports on the client side of the TTX board and the port with the maximum number is RX10/TX10. On the NMS, numbers 1 and 2 have been assigned to IN/OUT ports on line boards. Ports on tributary boards are numbered from 3. TTX is a tributary board and therefore its ports are numbered from 3. In other words, logical port 3 on the NMS corresponds to the RX1/TX1 port.
