After you have used the filter to display session data, complete these steps to display details about a session.

1.

If you have not already done so, display the details for the session whose resources you want to view.

2.

From the Session Details window, click the resource number for the resource that you want to

examine in more detail. The Session Resource Details window opens and displays the following
information about the resource you selected:

Note: The details that display vary according to the resource you select. The following lists all possible
details in alphabetical order for easy reference. 



Allocation Time - A time stamp indicating when the session-setup request is sent to the

DNCS.



ATM VCI - The virtual circuit identifier of the ATM card in the BFS BIG. (Shown only for the

ATM Connection resource.)



ATM VPI - The virtual path identifier of the ATM card in the BFS BIG. The VPI identifies a

bundle of virtual circuits that may be switched as a single unit. (Shown only for the ATM
Connection resource.)



Audio Encryption - The percentage of encryption applied to the session's audio stream. (This

field appears only for sessions on GoQAM modulators.) 



Bandwidth - The amount of bandwidth used by the selected transport stream ID (TSID).



Direction - The direction of the physical channel. A value of 1 indicates that the direction is

downstream. Currently this is the only value for a physical channel resource. 



Forward Error Correction - The type of FEC used. The following lists all possible values:



0 = FEC transmission system



1 = FEC DAVIC (Digital Audio Visual Council)



Frequency - The frequency (in Hz) that the physical channel uses.



Headend Flag - The headend that transmits the session to the access network. A value of 1

indicates the headend named by the headend ID.



Headend NSAP - The network service access point address of the headend transmitting the

session.



Inner Coding Mode - Per DSM-CC ISO/IEC 138-18-6, Generic coding of moving pictures and

associated audio information -- Part 6: Extensions for DSM-CC, the inner coding mode always
shows a fixed value of 15, indicating that trellis-coding is used.



Interleave Depth - The level of interleaving used by the QAM modulator carrying this

session. A value of 0 indicates a depth of 128:1. 



Modulation Format - The modulation used for this session. The following lists possible

values.



6 = QAM 16 



7 = QAM 32 



8 = QAM 64 



12 = QAM 128 



16 = QAM 256 



Modulation Mode - Per DSM-CC ISO/IEC 138-18-6, Generic coding of moving pictures and
