DSI Development Package for Linux - Release Notes Release 6.5.1

3.11 ISUP - BICC Timer Configuration (IPY00100565)

Previously when a BICC variant circuit group was configured, ISUP incorrectly

overwrote any user-configured timer values in the associated timer table.

This has been corrected so that user-configured timer values are preserved.

3.12 TCAP - Maximum instance now 255

TCAP now supports instance values in the range 0 to 255. When using

config.txt, the TCAP instance is configured using the <tcap_inst> parameter

in the TCAP_CONFIG command.

3.13 TCAP – Unnecessary use of large messages

TCAP now only attempts to allocate large messages when the payload

exceeds 320 bytes. Previously, when large messages were available TCAP

would allocate them in places where it was not necessary.

3.14 TCAP – Use of maximum incoming dialogs

This release corrects an issue that prevented TCAP working correctly when

configured for maximum (65535) incoming dialogs and zero outgoing dialogs.

3.15 TCAP – Dialog Idle Timer (IPY00102013)

This release corrects a fault with the TCAP Dialogue Idle Timeout which

previously resulted in timeouts greater than 6,553 seconds expiring early.

3.16 MAP – Generation of Begin Subscriber Activity

When the MAP user specifies MAPPN_dest_ref and MAPPN_orig_ref

parameters together with MAP-V1 application context parameter in a MAP-

OPEN-REQ message, the MAP module automatically sends a Begin Subscriber

Activity (BSA) component to TCAP. Previously if the user also included the

MAPPN_ellipsis parameter in the message the MAP binary could terminate.

This issue has been corrected.

3.17 M3UA – MTP label format in RX indications

M3UA now provides an indication of the MTP3 label format (or point code

size) in the id field of the API_MSG_RX_IND message. This allows the user

part module to determine the format of the MTP3 routing label contained

within the message.
