DSI SS7G41 Signaling Server – SIU Mode Release Notes
Release 1.2.3
41
3.2
CNHSS command - Tracing to Management Host
This release corrects the operation of the CNHSS command when used to
change the default management host (DMHOST) to ensure that any message
tracing will change immediately to the new DMHOST rather than waiting until
the next restart.
3.3
STCGP command – Circuit Group Status
This release corrects an anomaly with the STCGP command when displaying
the status of ISUP circuit groups that previously caused circuits in Wait for
ACM or Wait for RLC states to be considered in maintenance.
3.4
STN_LINK command - M3UA Network Appearance
To assist detection of incorrect configuration data, in the event that an
STN_LINK command sets NA to a non-zero value but does not set the option
bit 3 to indicate that NA is in use, the command will now be rejected.
3.5
Event Logging
The following maintenance events are now logged to the maintenance log and
to the management host: MTP2 events (MGT_MSG_SS7_EVENT), M3UA
errors (M3U_MSG_M3U_ERROR) and M3UA events (M3U_MSG_M3U_EVENT).
3.6
ISUP – Measurements
The SS7G41 maintains a number of ISUP Circuit Group measurements
accessible using the MSCGP command. These measurements include a count
of the number of calls answered and a measure of accumulated call duration
from the point of answer. By default the point of a call being ‘answered’ is
determined by generation or reception of either an Answer message or a
Connect message.
This release introduces a new run-time configuration option (bit 15 of the
<options> field in the ISUP_CONFIG command) which modifies the behavior
of the measurements so that the point at which the call is ‘answered’ is
deemed to be upon generation or reception of the Address Complete
message. This is more useful for certain types of application which use the
time between Address Complete and Answer to play tones or
announcements.
3.7
ISUP – IAM after RESET
This release includes a change to ensure correct operation when a locally
originated circuit group reset is immediately followed by an outgoing IAM
(before the Group Reset Acknowledgement is received). Previously it was
possible that the circuit required a second circuit group reset request to
recover from this unusual event.
3.8
M3UA – Trace for received Transfer Requests
A new M3UA trace event (bit 16) has been added to the input mask for M3UA
to enable receipt of outgoing Transfer Requests from user parts to be traced.
3.9
M3UA – 8-bit SLS values with 5-bit rotation
This release corrects the operation of SLS rotation to ensure that when
operating with 8-bit SLS values and 5-bit SLS rotation the most significant
bits of the SLS are preserved rather than being set to zero.
