available MGI channels. This is due to voice traffic possibilities. If it is not anticipated
that all ITP keyphones will be in use at the same time the probability factor of not
having a voice channel can be calculated based on the station activity or use. If an ITP
keyphone attempts to use an MGI card that does not have a voice channel available,
the ITP keyphone display will show "No MGI Channels Available"
The ITP 5100 series keyphones must be programmed to provide the keyphone IP
address, subnet mask, router gateway (if used) and MP10/MP10a (IP Server) address.
Each ITP keyphone must also have a User ID and Password. This User ID and
Password must match the User ID and Password in the OfficeServ 7100 system (MMC
840: IP SET INFO). The ID and Password are used to register the ITP keyphone to the
OfficeServ 7100 and retain the number associated with that particular ITP keyphone.
The ITP keyphones will register with the MP10/MP10a and be provided a default
extension number from the OfficeServ 7100 system provided the ID and password
match. The assigned default numbers can easily be changed to match the iDCS
keyphone station numbering plan. New ITP keyphone registrations can be enabled or
disabled via MMC 840 and MMC 841: IP SET INFO, SYS IP OPTN. See Figure 4 for the
relationship of ITP keyphone and iDCS keyphones.

When an ITP keyphone is connected and in conversation to another ITP keyphone the
MGI card audio codec is not involved when called on the private network side. The
MP10/MP10a is involved to provide call setup and tear down, programmable button
functions, displays and system feature accesses. However, an MGI port is used for
system features such as conference and transfer or internal paging as needed. See
Figure 5.
