Note:
The drivers for the Toshiba Strata DKTU station board are Windows native drivers that
start automatically when Windows loads.
To configure an ISDN or Robbed Bit T1 line, continue with the following sections.
Configuring an ISDN line __________________________________
If you have an ISDN line, verify that it is working correctly before you proceed to the rest of the
TeleVantage installation. See Appendix B, “Configuring Intel Dialogic Board ISDN
Parameters” for details.
Configuring Robbed Bit T1 signaling ________________________
If you have a Robbed Bit T1 line, you must verify that your T1 board is configured properly. Do
not proceed to the rest of the TeleVantage installation until you have checked your T1 board.
Although it is possible to configure your T1 line after you have installed TeleVantage, doing it
now ensures that TeleVantage can use your T1 line correctly as soon as it is installed.
Note:
This section is for Robbed Bit T1 installations only. If you have an ISDN T1 connection,
you do not need to configure your board.
If you experience problems with your Robbed-Bit T1 line after following the instructions in this
chapter, see “Troubleshooting Robbed Bit T1 problems” on page C-14.
About Robbed Bit T1 signaling
Robbed Bit T1 signaling replaces the least significant bits in specific locations in the T1
transmission with signaling information, such as whether the caller's line is on-hook or off-hook.
The specific locations that contain signaling information are called A-bits, B-bits, C-bits, and
D-bits. Robbed Bit T1 suppliers use different patterns of bit values to signal various events,
including the following:
The signaling information is contained in A, B, C and D bits where each bit can be set High or
Low. Robbed Bit T1 suppliers use different patterns of these bit values to signal various events,
including the following
Q
Incoming call
Q
Line drop
Q
Inbound pickup (answering an inbound call)
Q
Outbound pickup (seizing the line to make an outbound call)
Q
Disconnect
Q
Digit collection (capturing DID/DNIS or ANI information about an incoming call)
Check with your carrier to find out the precise patterns used to signal these events.
