5.8.4 H.235 Security
When this feature gets activated all messages between the HG 3500 and the IP
phones are authenticated. Authenticated messages will contain a Crypto Token
element. As Crypto Token handling requires precise time and therefore the local
system time is distributed cyclic to the IP endpoints.
For more details on configuration please refer to
-
H.235-Security".
5.8.5 Connecting IP Gateways to the Internet or via
External Providers
The connection of IP gateways to the Internet or external providers reveals a
security vulnerability ("insecure" LAN/WAN). An IP or MAC address filter must be
set to combat this problem. This can be done via the board's WBM.
WBM > Explorers > Security > MAC Address Filtering or WBM > Explorers
> Security > IP Address Filtering.
For a detailed description, see "HiPath 4000 V5, HiPath Gateways HG 3500 V4
and HG 3575 V4, Administrator Documentation"
techdoc/de/P31003H3150M1010100A9/index.htm).
IMPORTANT: The Resource Manager is released for use in standalone systems
with HFA and IPDA.
A project-specific release (PSR) is required to use the Resource Manager in a
HiPath 4000 network.
In a real, complex IP network the available bandwidth is typically not uniform in
all sectors.
The Resource Manager (RM) can administer and monitor the bandwidth for up to
800 sectors in a given IP network.
The RM updates a cluster matrix whenever a call is setup or torn down. The
matrix allows determination whether there is a resource shortage in any of the
involved sectors. Based on the configured bandwidth and the actual bandwidth a
call is either allowed to complete or rejected.
The RM calculates real bandwidth, taking compression settings, DMC, FAX, etc.
into account.
