ITG Engineering Guidelines

Leader And DCHIP Card Real Time Engineering
If you will be configuring an ITG Trunk node with five cards or less, then you
can safely skip this section. Real time engineering becomes important in the
case of nodes with more than five cards and very large networks, i.e. one
hundred or more ITG Trunk nodes.
Leader and DCHIP card standard confi
g
uration rules
1 Leader 0 with DCHIP and fully configured trunks supporting Leader 1
and all Followers. This rule covers most ITG Trunk node configurations.
2 Leader 0 with first DCHIP and fully configured trunks supporting half of
the Followers, and Leader 1 with second DCHIP and fully configured
trunks supporting the other half of the Followers. This rule covers
D-Channel redundancy with two ITG trunk routes per node.
3 Leader 0 with first DCHIP and partially configured trunks, Leader 1 with
second DCHIP and partially configured trunks supporting very large ITG
Trunk nodes in very large ITG Trunk networks. This rule covers very
large nodes and networks with multiple ITG trunk routes per node.
To setup an incoming voice (or fax) call, the Follower Card is responsible for
communicating with the Follower Card at the far-end to set up (and tear
down) the call. However, the Leader Card needs to assist the Follower Card
in obtaining the IP address of the far-end Follower Card and provide network
performance statistics so that the Follower Card can set up the call correctly.
The Leader Card CPU real time needs to be engineered to reserve enough
capacity to provide this call processing functionality.
The real time capacity of the Leader Card depends on various factors:
1 host module CPU (Intel 486 or Pentium-based)
2 the number of ports on the Leader Card configured to transmit voice or
fax traffic (and the selected codec and voice sample size)
3 the size of the ITG network (number of Leader Cards in the network)
4 number of probe packets sent to every Leader Card at remote node, etc.
Factor (1) impacts the real time capacity significantly. Factors (3) and (4)
impact the real time requirement of the software component Network
Monitoring Module on the Leader Card. In this section the following
