The Codec Data pane allows you to configure one or multiple Codec-Data within the Media Component Description of the N30 interface.

Include Codec Data

Indicates whether a Codec Data includes a media component description.

Tcl Parameter: N30NpcfCodecEn_0
Number of Codecs

Indicates the number of Codec Data you wish to provided.  The maximum number of Codec Data you may provide is 2.  Depending on the number of Codec Data you select, an equivalent number of Codec data tabs display for you to enter the actual codec data.

Tcl Parameter: N30NpcfNumCodecs_0
Codec 1

You may enter 1 codec data and description for each codec.

NOTE: You are responsible for entering correct codec description as multi-lines ASCII text.

 

AVP Line 1: Value Uplink or Downlink.  

  • Uplink indicates a configured SDP is used by UE for sending data to network.

  • Downlink indicates configured SDP is used by network for sending data to UE.  

AVP Line 2: Value Offer, Answer, Description. See RFC 3264.

SDP Lines: The Session Description Protocol (SDP) lines describe a media session. For syntax and Detail information see RFC 4566.

Tcl Parameter:

N30NpcfCodecLn1_0_1

N30NpcfCodecLn2_0_1

NOTE:

For example, if SDP Line value is m=audio 49170 RTP/AVP 0, the Codec-Data AVP value is as follows.

uplink \n description \n m=audio 49170 RTP/AVP 0 \n

Where, description indicates that the SDP lines are not being applied from SDP offer/answer messages.
