2.3
IPv6 Support and IPv4 Changes
This release adds IPv6 support and in doing so makes some changes to the
commands previously used for IPv4 configuration. 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.
For both IPv4 and IPv6, static IP addresses are now specified in CIDR
notation containing IP address followed by the ‘/’ separator followed by the
subnet mask (which is an integer identifying the number of leading (i.e.
significant) bits in the mask).
To accommodate IPv6 configuration the old commands IPEPS/IPEPP have
been replaced (for IPv4 and IPv6) by the new commands IPNIC and IPNIP for
configuring IP Network Interfaces. The STEPP/MSEPP commands have been
replaced by STNIP and MSNIP which display status and measurements for the
network interfaces.
The IPGWx commands have been modified to support IPv6. As both IPv4 and
IPv6 networks can have a default gateway the ‘Default’ identification should
be assigned to the IPNW parameter rather than the IPGW id parameter.
When configuring non default gateways the IP Network and Network Mask are
both configured using the IPNW in CIDR notation.
A new config.txt command IP_TOKEN allows the user to create a token
associated with a numerical IPv6 (or IPv4) address. This token can then be
used throughout config.txt when configuring IP addresses without the need to
retype the full IP address each time.
2.4
SCCP_GTT Command
This release adds the ability to have separate Global Title Translation (GTT)
tables for incoming and outgoing messages. This is achieved by the addition
of a new optional parameter (GTTSRC) to the config.txt command SCCP_GTT.
When GTTSRC=LOCAL the command only applies for messages generated by
a local sub-system (ie. outgoing messages). When GTTSRC=REMOTE the
command only applies to messages passed up to SCCP from the network (ie.
incoming messages). If GTTSRC=ANY (or the parameter is omitted) the
command applies to all messages.
A new optional parameter (BAK_DUAL) has been added to the SCCP_GTT
command that when set to Y causes any SCCP messages that matches the
GTT pattern, but cannot be routed due to network failure, to be passed to
SCCP on the partner unit so that it can reattempt routing.
A new optional parameter (OPTIONS) which is reserved for future use has
been added to the SCCP_GTT command.
2.5
Mobile Number Portability Option
This release supports a purchasable run-time option which in conjunction with
Message Router functionality allows the SS7G41 to work in conjunction with
the Dialogic Directory Services Engine (DSE) which is an element of the
Dialogic
®
ControlSwitch™ System for the realization of Mobile Number
Portability. Further information on this feature is available on request.
