An i40 might provide an adequate number of lines and trunks for the current business
requirements but not for increased requirements in two years based on growth assumptions. Or,
an i40 might provide enough lines and trunks for the next several years but another parameter,
such as the number of DSPs to handle large Fax volumes might not be sufficient. In either case,
one of the i120 constructs would be a better choice.
Table 1:
i40 constructs on page 27 and Table 2: i120 constructs on page 29 provide the
information needed to choose a construct.
Note:
Note: The list of available constructs might change over time. Check on the Avaya
Distributed Office web site for the latest set of available constructs.
i40 constructs
Each i40 construct contains the following ports:
● One console cable port
● One interface USB port (located on the chassis where you connect the Disk on Key)
● One Contact Closure Adjunct (CCA) port
● One Ethernet WAN port (not used with Distributed Office)
● Eight Ethernet LAN Power over Ethernet (PoE) ports
● One USB port (for use with a USB modem for servicing the platform)
● One Ethernet services port
● Two analog line ports
In addition to these ports, the i40 contains additional ports based on its construct. Table 1
shows
the three i40 constructs, and a description of what additional ports are available for each.

only.
