ITG MAT PC management configuration
This section provides guidelines on how to set up MAT to support the
Meridian Internet Telephony Gateway (ITG) Trunk 2.0 card. The MAT
application name is ITG ISDN IP Trunks.
MAT ITG Engineering rules
MAT ITG can manage multiple nodes with multiple ITG cards. The
maximum number of ITG cards that can be configured by MAT depend on
the following:
1 All MAT ITG data is stored in a single database file. The entire database
is read into PC memory when you launch the program. If a large ITG
network is to be managed from a single MAT server, then each MAT PC
client should have more than the minimum RAM requirements of 32 Mb,
and the recommended RAM is 64 Mb or more. If the data is stored on a
MAT server, the application launch time will increase as the size of the
ITG network grows (this also depends on the network speed).
2 In theory, a single MAT installation can support up to 500 Meridian 1s.
However, MAT applications requiring real time, such as Traffic Analysis
retrieval of traffic data is limited to a much smaller number of systems.
3 MAT Alarm Notification can receive a maximum of 20 SNMP traps per
second based on the recommended PC configuration). In large networks,
it is recommended that multiple MAT PCs be used to collect traps from
ITG cards, each PC supporting one or more ITG nodes. Alarm
notification scripts can be used to forward critical alarms to a central
MAT PC or Network Management application.
