DSI Development Package for Linux - Release Notes Release 6.2.3

3.10 SCTPN – Message discard during congestion

Previously when an association was configured as the server end, if the

remote end of an SCTP association became congested new outgoing

messages were buffered instead of being discarded. This has been corrected

to prevent exhaustion of messages within the software environment.

3.11 M2PA – Throughput Licensing

Prior to this release the M2PA throughput licensing mechanism incorrectly

calculated the number of received octets. This has been corrected.

3.12 M3UA - Heartbeat

M3UA now supports the ability to turn on heartbeats at the M3UA level. This

capability is not usually required as the underlying SCTP protocol has its own

heartbeat mechanism. For further information refer to the M3UA

Programmer's Manual.

3.13 MST - Virtual packets for an invalid port

In the previous release an IP Message (MST_MSG_IP_MSG) received for an

invalid port (out of range or not configured) was not handled correctly. In this

release the IP message will be discarded correctly.

3.14 MST - Port device names

The Configure MST Port message (MST_MSG_CFG_PORT) in the previous

release would reject an empty device name for ports of port type “virtual”.

This is now accepted. Empty device names for ports of port type “Ethernet”

will still be rejected.

3.15 MST - Traffic Filtering

The TAP configuration message (MST_MSG_CFG_TAP) has been updated to

allow monitored traffic to be filtered according to the SS7 event mask

(ss7_mask) and SIGTRAN event mask (stn_mask) parameters.

The MGT_MSG_CFG_TAP options parameter settings are:

Bit 0 – When set traffic will be monitored if it meets selection criteria within

both the SS7 event mask and the SIGTRAN event mask. When bit 0 is not set

traffic will be monitored if it meet at least one selection in one of the masks.

Bits 1-31 – Reserved for future use and should be set to zero.

3.16 s7_mgt - LIU_CONFIG <options>

The LIU_CONFIG command now supports an <options> parameter which is

used to further select advanced clocking options for certain board types (eg.

SS7MD). The full syntax of the command is:

LIU_CONFIG <board_id> <liu_id> <liu_type> <line_code> <frame_format>

<crc_mode> [<build_out> <options> ]

Use of the <options> parameter is detailed in the per-board user

documentation.
