Allocated Cell Rate | Indicates the allocated cell rate (specified in cells per second) for traffic received by the interface for this service category. This is the bandwidth allocated to connections. For guaranteed service categories, this value increases as a result of connection setup and decreases as a result of connection release. For non-guaranteed service categories, this value is always 0. |

Total Connections | Number of existing connections at this interface. |
Admin Address | Address assigned for administrative purposes, for example, an address associated with the service provider side of a public network UNI. If the interface has no assigned administrative address, or if the address used for administrative purposes is the same as that used for ifPhysAddress, then the Admin Address is an octet string of zero length. |
ATM Address Type | Type of primary ATM address configured for use at the ATM interface. |
NSAP (network service access point) Address | Allows you to specify the NSAP address. |
Configured VP Interface | Number of configured VP interfaces at this physical interface. |

The status information for the selected DMT line card appears at the right.
The DMT Interface Status window contains two tabs—Line and Channel.
The Line tab displays downstream and upstream line status information, as well as line status information that is common to both parameters, for the selected DMT line card. The Line tab contains two areas—Downstream/Upstream Parameters and Common.
Table 7-5 defines the fields that are located in the Line tab.

The possible state values displayed for upstream parameters are as follows:
|
Issue Number | Reports the issue number of the standard according to which the downstream DMT ADSL transceiver is currently operating. The issue number is determined by the hardware and is transmitted by the downstream in C-MSGS1 during initialization. The upstream device transmits the issue number in an R-MSGS1 message during initialization. The possible issue numbers are:
|
Enterprise Specific State | The value of this object specifies the enterprise-specific status of the downstream device. Possible values include other or standard. If the value is other, and the downstream device is in an unrecognized state, the value of this object is unknown. If the value is other and the downstream device is in an recognized state, the value of this object specifies the enterprise-specific state of the downstream device. |

After initialization, unknown is reported until sufficient autonomous EOC messages have been transmitted to determine the true capability of both ATUs. The possible values displayed and the corresponding meaning is as follows:
|
Trellis Encoding | Reports whether trellis coding is used on the DMT line. Use of trellis coding is determined at line initialization with C-MSGS1 and R-MSGS1 exchanges and does not change until the line is reinitialized. The possible values displayed are as follows:

| 1FEC = forward error correction |
After you deploy a Synchronous Optical Network (SONET) interface, you can access status information for that interface in the SONET Interface Status window.

The Virtual Tributary tab (Figure 7-11) displays errors encountered while converting between STS and OC signals.
Table 7-11 defines the fields that are located in the Virtual Tributary tab.
| Field | Definition |
|---|---|
Remote Failure Indication | A SONET port status indicator activates when a path remote defect indication (PRDI) occurs and does not clear throughout the alarm integration period, which is typically 2.5 seconds. A path remote failure indication (PRFI) occurs when bit 5 of the G1 byte is set to 1 for 10 consecutive frames. This occurrence begins the alarm integration period. If this period elapses without the detection of 10 consecutive frames in which all G1 bit 5s are set to 0, the PRFI indicator activates. The PRFI indicator clears when a PRDI does not occur for a time interval equal to the alarm deactivation period (typically 10 seconds). |
Alarm Indication Signal | Reveals whether the virtual tributary alarm indication signal errors are enabled or disabled. |
Loss of Pointer | Indicates whether the virtual tributary loss of pointer errors are enabled or disabled. |
Remote Defect Indication | Reveals whether the path remote defect indication errors are enabled or disabled. |
Unequipped | Indicates STS payload unequipped—no virtual tributary-originating equipment. |
Signal Label Mismatch | Incorrect payload type signal label mismatch on a SONET line. |
No Defect | Transition from failure to no alarm state occurs when no defects (for example, LOF) are received for more than 10 seconds. |
