Stream Bandwidth (kbits/sec): This is the amount of bandwidth in kilobits per second required by
the stream, automatically computed based on number of TDM Bus Frames per Packet .
Stream Delay (milliseconds): This is the initial jitter/lead position in the Jitter Buffer, automatically
computed based on Jitter Buffer Size .
Stream Program Type: Defines the contents of the underrun buffer based on the type of program
stream. The underrun buffer gets played out to the internal TDM bus or external T1/E1 port any time
there is no packet from the IP network to play. Since different types of channel modules react
differently when receiving long strings of bits with a zero value or a one value, changing the value of
the underrun byte can improve how the module behaves when the network drops packets. For
example, APT-x compression modules mute faster when presented with a long string zero valued bits.
Select
Compressed Audio/Data (0 channel value), Linear Audio/Voice (255 channel value), or
Enter Underrun Value Manually to type a value between 0 and 255.
Packet Underrun Byte: When Enter Underrun Value Manually is selected in the Stream
Program Type field, the Packet Underrun Byte field is enabled so that you can define the value of
the underrun byte. Type a value between 0 and 255.
Cancel: Click this button to return to the Streams Table page without creating a new stream.
Prev: Click this button to return to the Stream Creation – Stage 3 page.
Next: After completing the Stream Creation – Stage 4 page, click this button to advance to the
Stream Creation Summary page (Figure 4-59). If the TDM bus associated with this stream is not
connected to an IP port in the TDM bus map, a warning splash page appears.
