DSI SS7G41 Signaling Server – SIU Mode Release Notes
Release 2.2.9
13
NOTE: If a software release (old or new) is manually loaded and the unit
restarted without using the RESTART=PREVIOUS then the restoration
procedure will not revert to previous configuration files.
2.2
SCCP – Rebalance of Class 0 Traffic
This release introduces the ability for Connectionless Class 0 SCCP traffic to
be evenly balanced towards a Remote Signaling Point through regeneration of
the SLS in a cyclic manner.
The option can be selected on a per-RSP basis by setting bit 6 in the
rsp_flags field of the SCCP_SSR command when configuring the Remote
Signaling Point.
2.3
SCCP - Multiple Global Title Translation Tables
This release introduces the concept of multiple Global Title Translation Tables
which allows the MAP user to select a different SCCP routing plan on a per
dialogue basis.
Selection of the Translation Table is performed using a new integer parameter
RIID (Routing Indicator Identifier) which takes a value between 1 and 65535
and acts as a token to identify the table. Refer to the
MAP Programmer’s
Manual
for further details.
The RIID parameter is optional and can be used when configuring the GT
Translation (in the SCCP_GTT config.txt command), and when configuring a
Remote Signaling Point (in the SCCP_RSP command).
2.4
MAP – Update MAP LCS Services
This release updates the MAP Subscriber Location Report and Send Routing
Info for LCS services to MAP TS 29.002 v12.3.0 to allow more data to be sent
and received.
2.5
MAP – Options to Control Default TCAP QoS
This release adds two new global MAP options to control the default value for
the Quality of Service (QoS) parameter sent to TCAP (when QoS is not
explicitly specified by the MAP user). These options are supported in the
OPTIONS parameter of the MAP_CONFIG command as follows:
Bit 8, when set, causes the ‘Return on Error’ field to be set by default.
Bit 9, when set, causes Sequence Control to be disabled by default (selecting
Class 0 operation).
2.6
SCTP – Per-association options
The following new per-association options are supported in the OPTIONS
parameter of the STN_LINK command:
Bit 8, when set, disables use of the Nagle algorithm to ensure that outgoing
packets are transmitted without delay.
Bit 9, when set, disables path MTU discovery and selects a fixed MTU value of
1438.
Bit 10, when set, designates the path associated with the first remote IP
address (RIP1) as the primary SCTP path that if available will always be used.
