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 c ard s. The
maximum number of ITG cards that can be configured by MAT depend on
the following:
1All MAT ITG data is stored in a single dat abas e file . The enti re d ataba se
is read into PC memory when you launch the program. If a large ITG
network is to be managed from a sin gle MAT ser ver, the n eac h MAT PC
client should have more than the m inimum RAM r equirements 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 incre as e as the size of the
ITG network grows (this also depends on the network speed).
2In 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.
3MAT Alarm Notifica tion can receive a ma ximum of 20 SNMP t raps per
second based on the recommended PC configuration ). In large netwo rks,
it is recommend ed that multiple MA T 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.
