ITG engineering guidelines
There are several configurations where it is acceptable to put multiple
IP Trunk 3.01 nodes on the same dedicated ELAN and TLAN segments
(separate subnets), or on a dedicated ELAN/TLAN segment (single subnet):
1 Several IP Trunk 3.01 (and later) nodes belonging to the same customer
in the same system can be configured to route calls with different codecs
depending on the digits dialed or the NCOS of the originating telephone,
or to limit the maximum number of IP Trunk 3.01 (and later) calls to a
particular destination node. The traffic engineering considerations on the
TLAN subnet should determine how many different IP Trunk 3.01 nodes
can be configured on the same LAN segment.
2 Layer 2 (10 BaseT or 100 Base TX) switching equipment or ATM
infrastructure can support a Virtual LAN (VLAN) segment that is
distributed across a campus or larger corporate network. In this case,
some or all of the ITG destination nodes can be on the same subnet.
3 In test labs, training centers, and trade shows, it is common for
destination nodes to be located on the same LAN segment and subnet.
Do not place other IP devices, either Nortel Networks' or other vendors'
products, on the same TLAN subnet as the IP Trunk 3.01 (and later)
nodes.
