Debug terminal access

The Media Card provides two RS-232 ports—one accessible via the

NTMF94BA backplane cable, and the other using the maintenance port on the

card faceplate. Only the backplane cable, labeled COM1, provides access to the

Media Card for both OA&M and debugging purposes. The pinouts for the RS-

232 ports are listed in Table 5, "RS-232 backplane signals," on page 18, and in

Table 6, "Faceplate mini-DIN connector," on page 19. Messages indicating the

completion of each self-test phase, as well as any detected faults, are printed.
