| INT atmPhyMibLevel | 1.3.6.1.4.1.495.2.1.6.61.1 | INTEGER | read-only | Used to determine current MIB module release supported by agent. Object is in decimal. |
| atmPhyInterfaceConfTable | 1.3.6.1.4.1.495.2.1.6.61.10 | | not-accessible | A table containing information pertaining to one ATM PHY interface. |
| atmPhyInterfaceConfEntry | 1.3.6.1.4.1.495.2.1.6.61.10.1 | | not-accessible | Defines an entry in the ATM PHY interface table. |
| INT atmPhyConfTxClocking | 1.3.6.1.4.1.495.2.1.6.61.10.1.1 | INTEGER | read-write | Defines how the physical line's transmit clock will be derived. For DS1 and E1 ATM implementations, this object defines the interface clocking, and the corresponding clocking object at the DS1 and E1 layer becomes ineffective. This is contrary to non-ATM implementations where it is the clocking object at the DS1 and E1 layer that defines the interface clocking.
Options:
synchronized (1): The transmit clock will be derived from the receive clock. This is more commonly referred to as 'loop' timing.
unsynchronized (2): The transmit clock will be derived internally from an oscillator, and will not be synchronized to the receive clock. |
| INT atmPhyConfRxLoopback | 1.3.6.1.4.1.495.2.1.6.61.10.1.2 | INTEGER | read-write | Defines the type of loopback mode.
Options:
none (1): Normal operating mode. All received cells are sent to the ATM layer.
line (2): All received cells are re-transmitted immediately. Received cells are not processed and are not sent to the ATM layer. This setting has no effect for E1 cards.
cell (3): All received cells are first processed and then passed to the transmitter to be sent back out. Received cells are not sent to the ATM layer. |
| INT atmPhyConfFrameFormat | 1.3.6.1.4.1.495.2.1.6.61.10.1.3 | INTEGER | read-write | Defines the type of framing used at this interface.

FIFO bypass can be used to reduce latency at this interface (through the PHY device).
This object will take on value 'disabled' in the initial phase since the ATM layer does not support cell rate decoupling, and idle/unassigned cell processing. |

If 'enabled', the polynomial X^6+X^4+X^2+1 is added to the HCS octet of each cell prior to transmission as required by the ATM Forum UNI specification. The coset function prevents the HCS octet within a cell from taking on a zero value. |

If 'enabled', the polynomial X^6+X^4+X^2+1 is removed from the HCS octet of each received cells before comparison with the calculated result as required by the ATM Forum UNI specification. The coset function prevents the HCS octet within a cell from taking on a zero value. |

If 'enabled', cell payloads are scrambled using the self synchronizing polynomial X^43+1. If 'disabled', cell payloads are transmitted unscrambled. |
| SWI atmPhyConfCellDescrambling | 1.3.6.1.4.1.495.2.1.6.61.10.1.8 | Switch | read-write | Defines whether received cell payloads are descrambled. If 'enabled', received cell payloads are descrambled using the self synchronizing polynomial X^43+1. If 'disabled', cell payload are not descrambled. |
| INT atmPhyConfTxFifoDepth | 1.3.6.1.4.1.495.2.1.6.61.10.1.9 | INTEGER | read-write | Defines the size of the transmit FIFO in cells. Reducing the FIFO depth permits cell latencies to be minimized at this interface (through the PHY device).
It is not recommended that the FIFO depth be set to 1 cell, since half the bandwidth will be lost to idle/unassigned cells. For minimum latency and maximum throughput, a FIFO depth of 2 cells is suggested.. |

For each mask bit that is set, the PHY will process received cells with the corresponding bit(s) set in the H2 octet. For each mask bit that is reset, the PHY will discard received cells with the corresponding bit(s) set in the H2 octet. A logical OR is performed across all mask bits within the same mask byte, and across all four mask bytes. |
| INT atmPhyConfRxUserProgH3Mask | 1.3.6.1.4.1.495.2.1.6.61.10.1.22 | INTEGER | read-write | Defines the bit mask pattern for the third octet (H3) of a received cell. For each mask bit that is set, the PHY will process received cells with the corresponding bit(s) set in the H3 octet. For each mask bit that is reset, the PHY will discard received cells with the corresponding bit(s) set in the H3 octet. A logical OR is performed across all mask bits within the same mask byte, and across all four mask bytes. |
| INT atmPhyConfRxUserProgH4Mask | 1.3.6.1.4.1.495.2.1.6.61.10.1.23 | INTEGER | read-write | Defines the bit mask pattern for the third octet (H4) of a received cell. For each mask bit that is set, the PHY will process received cells with the corresponding bit(s) set in the H4 octet. For each mask bit that is reset, the PHY will discard received cells with the corresponding bit(s) set in the H4 octet. A logical OR is performed across all mask bits within the same mask byte, and across all four mask bytes. |

disableHCSErrorGeneration (4): Disables the insertion of an incorrect Header Error Checksum (HCS) within consecutive transmitted cells (assigned or unassigned). |
| INT atmPhyConfPlcpControl | 1.3.6.1.4.1.495.2.1.6.61.10.1.45 | INTEGER | read-write | Defines the PLCP error generation controls permitted at this interface. This object is bit-mapped and can permit a maximum of 8 simultaneous error controls. Once the controls are initiated, the selected errors are generated for a period of time specified by object 'atmPhyConfPlcpControlTimer'. Error generation can be restarted at any time.
To enable a specific control, its bit must be set. To disable a specific control, its bit must be reset. The controls are assigned the following bits:
