Viewing the SONET Interface Status Window—Path Tab

The SONET Interface Status window Path tab opens, which displays errors encountered while mapping signals into the format required by the Line layer. The Path tab has one area, Path. (See Figure 7-15.)

The fields in this tab are described in Table 7-15.

Table 7-15   SONET Interface Status Window—Path Tab Field Descriptions

Field  Description 

Signal Label Mismatch

Displays a green light to indicate incorrect payload type signal label mismatch on a SONET line.

STS—Alarm Indication Signal

Displays a green light to indicate that the path alarm indication signal errors are disabled.

STS—Remote Defect Indication

Displays a green light to indicate that the path remote defect indication errors are disabled.

STS—Loss of Pointer

Displays a green light to indicate that the path loss of pointer errors are disabled.

Unequipped

Displays a green light to indicate STS payload unequipped—No path-originating equipment.

Defect or No Defect

Transition from green to red (failure to no alarm state) when no defects (for example, LOF) are received for more than 10 seconds.

Viewing SDSL and G.SHDSL Interface Status

The SDSL Status window displays status information for a selected SDSL or G.SHDSL card. To view the SDSL Status window, follow these steps:


Step 1   In the Map Viewer window, within the Physical view, right-click an SDSL card or a G.SHDSL card whose interface status you want to view.

Step 2   Choose Cisco DSL Manager > Interface > Status > XDSL > SDSL from the object menu.

The SDSL Status window opens. (See Figure 7-16.)


Figure 7-16   SDSL Interface Status Window


Step 3   Highlight the relevant chassis, card, and SDSL or G.SDSHL interface from the list boxes on the left side of the window.

The status information for the selected SDSL or G.SDSHL line card displays in the window. In the SDSL/G.SHDSL area, the Downstream column applies to both SDSL and G.SHDSL line cards. The Upstream column applies only to G.SHDSL line cards.



Table 7-16 describes the fields that are located in the SDSL Interface Status window. The values in the Downstream column refer to both SDSL and G.SHDSL. The values in the Upstream column relate only the G.SHDSL line cards.

Table 7-16   SDSL Interface Status Window Field Descriptions

Field  Description 
SDSL/G.SHDSL

State

Specifies the state of the STU-C transceiver. Valid values are:

  • other(1)
  • idle(2)—Administratively down
  • training(3)—Transceiver training in progress
  • steadyState(4)—Nominal mode of operation
  • testing(5)—Transceiver in loopback or running BERT
  • downloading(6)—STU-C code download in progress
  • downloadingFailed(7)—STU-C code download failed

Output Power

Specifies the measured total output power transmitted by this STU-C. This is the measurement that was reported during the last activation sequence.

Rate

Specifies the rate the STU-C transceiver was able to obtain following training.

Defect

Specifies any possible defects currently being exhibited by the STU-C.

Signal/Noise Margin

Specifies the signal/noise margin that this STU-C uses for its receive signal.

Gain

Specifies gain applied to this STU-C receiver.

G.SHDSL

Power Difference

Displays the measured difference in the total power transmitted by the peer STU-C and the total power received by this STU-C.

Viewing FlexiCAP Interface Status

The CAP Interface Status window displays status information for a selected flexiCAP card. To view the CAP Interface Status window, follow these steps:


Step 1   From the Map Viewer window, within the Physical view, right-click the flexiCAP card whose status you want to display.

Step 2   Choose Cisco DSL Manager > Interface > Status > > XDSL > CAP from the object menu.

The CAP Interface Status window opens. (See Figure 7-17.)


Figure 7-17   CAP Interface Status Window


The relevant chassis, card, and flexiCAP interface that you selected displays in the list boxes on the left side of the window.

The status information for the selected line card displays on the right.



Table 7-17 describes the fields that are located in the CAP Interface Status Window.

Table 7-17   CAP Interface Status Window Field Descriptions

Field  Description 

Current State

Specifies the state of the ATU-C transceiver.

Current Receiving SNR

Specifies the signal-to-noise ratio for the upstream (receive side) data channel.

Current Receiving Gain

Specifies the measure of loop attenuation over the entire DSL frequency spectrum. The card uses an algorithm to boost receiver gain so that attenuation can be corrected for proper support of a given receive data rate.

Average SNR (tenth-dB)

Specifies the average signal-to-noise ratio for the upstream (receive side) data channel.
