Hello, guys!

We are trying to open dump with SSCOP/ALCAP protocol stack in Wireshark!

We use following guide for pcap header format: https://wiki.wireshark.org/Development/LibpcapFileFormat We use following guide for data type format: http://www.tcpdump.org/linktypes.html

We tried to change following parameter manually: guint32 network; /* data link type */

We tried following value: LINK-LAYER HEADER TYPE VALUES LINKTYPE_ name LINKTYPE_ value Corresponding DLT_ name Description LINKTYPE_NG40 244 DLT_NG40 Pseudo-header for ng4T GmbH's UMTS Iub/Iur-over-ATM and Iub/Iur-over-IP format as used by their ng40 protocol tester, followed by frames for the Frame Protocol as specified by 3GPP TS 25.427 for dedicated channels and 3GPP TS 25.435 for common/shared channels in the case of ATM AAL2 or UDP traffic, by SSCOP packets as specified by ITU-T Recommendation Q.2110 for ATM AAL5 traffic, and by NBAP packets for SCTP traffic.

But Wireshark shows "network type 244 unknown or unsupported"

How should we operate to open this pcap?
