Configuring Robbed Bit T1 signaling manually
If your carrier uses C and D bits for Robbed Bit signaling, you must configure the C and D bits
manually.
Note:
See Administering TeleVantage for information on adding a Robbed Bit T1 span.
1. In the TeleVantage Administrator, edit the Robbed Bit T1 span in the Trunks view.
2. Click the Signaling tab. Double-click each event in turn to open it in the Definition
dialog box.
3. Make sure that all call events are defined to match your carrier’s usage. Ask your
carrier how it defines each event, and check that the definition is entered exactly as it
needs it to be entered. If an event does not match the definition used by your carrier,
redefine the actions that make up the event. If an action is undefined, click
Add. To
define an action, click
Edit to open the Action dialog box, and then select one of the
choices under
Actions:
Wait for bit state. In this action, TeleVantage waits to receive bits sent by the
carrier. Select the
Bit signal (pattern of bits to be sent by the carrier), and then enter
the
Timeout in milliseconds.
Send bit state. In this action, TeleVantage sends bits to the carrier. Select the Bit
signal
that TeleVantage will send to the carrier.
Pause. In this action, TeleVantage waits for a specific number of milliseconds.
Enter the
Timeout in milliseconds.
Retrieve digits. In this action, TeleVantage retrieves ANI, DID/DNIS, or filler
digits sent by the carrier. Make sure your digit collection setting matches the
sequence in which your carrier sends DID and ANI data to begin a call. Define the
sequence by adding
Retrieve Digits actions of the appropriate type, either DID, ANI,
or Filler, to match how your carrier sends the data. Click Add to choose each
Retrieve Digits action in the Digit Collection - Action dialog box.
