Explanation and action
CARDINFO | see subfields | Card information |
|
| This field specifies the card data and |
|
| consists of subfield APPLPEC. |
APPLPEC | NT9X84AA | Application product engineering code |
|
| Enter the PEC of the application card. |
|
| Card NT9X84AA is used with EIU |
|
| applications. |
|
| This field consists of subfields PBPED, |
|
| HEARTBEAT, and MAC_ADDRESS. |
PBPEC | NT9X85AA | Paddle board product engineering code |
| or | Enter one of the PECs. |
| NT9X85BA |
|
|
| Enter NT9X85AA for EIU coax |
|
| applications. |
|
| Enter NT9X85BA for EIU unshielded |
|
| twisted pair applications. |
HEARTBEAT | YES or NO | Heartbeat |
|
| Enter YES if the EIU expects a |
|
| heartbeat indication signal from the |
|
| media access unit (MAU) connected to |
|
| it; otherwise, enter NO. |
|
| Yes is allowed only if the MAU supports |
|
| heartbeat of signal quality error (SQE) |
MAC_ | 000075F00000 to | Media access control address |
ADDRESS | 000075FFFFFF | Enter a |
|
| representing the MAC address. |
|
| The MAC address is represented in |
|
| hexadecimal without any spaces |
|
| between digits. The MAC_ADDRESS |
|
| must be of the form 000075Fxxxxx. |
|
| MAC addresses for EIUs are defined by |
|
| Nortel. Refer to “Appendix I: Obtaining a |
|
| MAC address” for more information on |
|
| MAC addresses. |

EIU MAC addresses
By industry convention, MAC addresses for networking devices are unique worldwide. In typical networking devices, the MAC address is burned into a PROM on the circuit pack. However, for EIUs on the
