Displaying the DS0 Signaling Bits
The show t1/e1 ds0Signaling command provides a real time display of the bit pattern for voice channel signaling bits ABCD. You can use the entry option to view a specific DS0 channel, or the table option to view all DS0 channels within the Passport 4430/50/55 unit.
To display the voice signaling bit pattern of a single DS0 channel, enter the following command:
CLI> show t1e1 ds0Signaling entry
You will be prompted to specify the following:
| Parameter | Range of Values | Required Action |
|---|
| <LineIndex> | localEnd(T1=DSX-1/E1=L1) | networkEnd(T1=DS-1/E1=L2) | Select localEnd or networkEnd. |
| <DS0Index> | INTEGER (1..30) | Specify the DS0 channel whose signaling bits you want displayed. |
To display the voice signaling bit pattern of all DS0 channels, enter:
CLI> show t1e1 ds0Signaling table
A sample display for a single port E1 is shown below:

*The values shown in the RxABCDBits and TxABCDBits columns are decimal equivalents of the binary values presented by signaling bits ABCD. For example, the value 14 would translate as follows:
|
The RxABCDBits (receive) column shows the activity of the signaling bits from the PBX to the digital voice module. The TxABCDBits (transmit) column shows the activity of the signaling bits from the digital voice module to the PBX. Interpretation of the signaling bits is dependent on the CAS format selected for the specified DS0 channel.
