ITG Trunk 2.0 ISDN Signaling Link (ISL) Description, Installation and Operation
Single vs. separate subnets for T-LAN and E-LAN
It is highly recommended that you use separate subnet s a nd sep arate T -LANs
and E-LAN for the ITG Trunk voice and management networks. Separate
subnets implies separate port groups on hubs or switches for T-LANs and
E-LAN and separate IP Gateway (Router) interfaces with one subnet per
router interface.
For traffic reasons, you should use separate subnets for nodes cons isting of
multiple 24-Port ITG Trunk cards.
Refer to the Engineering Guidelines sections “Se t up a system with separate
subnets for voice and management” on page130 and “Single subnet option
for voice and management” on page131.
