Planning of IP address
Item Description
Card 1
The IP address is 10.22.11.9/24, and the gateway is 10.22.11.254.
This network port is used to catch the packets of the MGC (whose
address is 10.22.11.2).
Card 2
The IP address is 10.22.3.201/24, and the gateway is 10.22.3.254.
Peer IAD
The IP address is 10.2.128.65/28. This address can be pinged
through from card 1 and card 2.
When card 2 is selected for the OPENEYE, monolog occurs
when the OPENEYE and IAD call each other. Voice can be heard on a
phone set under the IAD, but the peer-end voice cannot be heard on
the OPENEYE.
When card 1 is selected for the OPENEYE, communication is
normal.
When the OENEYE is installed in a PC with two network cards,
the incoming voice stream must be processed.
8.6
Voice Quality Deterioration
8.6.1 Fault
Jitters occur in communication and voice cannot be heard clearly.
8.6.2 Cause
Since only a few IADs in this office operate like this, it can be
seen that this is a network fault.
