Release 2.2.3

Overview
This release is a significant feature release which adds support for IPv6, adds
the ability to provide Mobile Number Portability in conjunction with the
Dialogic
®
ControlSwitch™ System and provides a number of OA&M
enhancements.
IPv6 is supported for the configuration of SIGTRAN protocol software as well
as SIU host links (RSI), NTP, SNMP, IP Gateways and firewalls. IPv6 access to
the unit is permitted using Browser, Telnet, FTP, SFTP and SNMP.
Mobile Number Portability (MNP) is supported in conjunction with the Dialogic
Directory Services Engine (DSE) which contains the MNP database.
This release supports enhanced syntax for config.txt commands. The new
syntax allows parameters to be entered in any order and allows optional
parameters to be omitted. Each parameter is entered in terms of parameter
name and parameter value
The release also includes major enhancements to the Alarm List including
addition of new fields, addition of an Alarm Log (which list historic alarms)
and the additional logging of alarms to a text file for offline analysis.
This release includes major new SNMP enhancements including the ability to
view the active alarm list using SNMP and provision for SNMP notifications on
changes of state of alarms. In addition, this release addresses an important
syntax issue with respect to the SNMP MIB.
This release is fully backwards compatible with Release 1.3.9, however there
are some important differences as follows which should be read and
understood prior to commencing installation:
This release should be used in conjunction with SNMP MIB V4.xx, which
owing to the correction of a syntax error in the MIB is not fully backwards
compatible with the previous MIB. A mechanism is provided to allow
users to select the previous mode of operation as a short term option to
ease migration. See below for details of the changes and how to retain
compatibility if required.
IP configuration is maintained when upgrading to this release however
downgrading to an earlier (pre 2.0.3) release will result in the reset of the
system IP configuration to its default values. It is therefore important to
take a backup of the config.txt and config.CF3 files prior to upgrading to
this release.
The IP configuration commands for local IP address configuration have
changed. Instead of using IPEPP/IPEPS to configure local IP addresses the
commands IPNIC/IPNIP/IPNII/IPNIE should be used.
For local IP Address configuration, IP Gateway and IP firewall
configuration rather than using a separate SUBNET mask the IP address
and netmask should expressed in CIDR notation where the IP address
and netmask are separated by the '/' character and netmask is a integer
identifying the number of leading (i.e. significant) bits in the mask.
IP firewall configuration is maintained when upgrading to this release
however downgrading to an earlier (pre 2.0.3) release will result in the IP
firewall configuration reverting to the values it held prior to system
upgrade.
