Information
Install an IP Media
Processor and an IPSI
board in every survivable
Port Network.
In all IPSI controlled Port
Networks, verify that the
TN570D board is used.
ESS is not supported in a
Direct Connect
environment. The Direct
Connect environment must
be converted to an IP
Connect environment.
All ATM PNC and CES
boards must be TN2306B
boards.
If the ATM is local to the
Port Networks, a five to one
IPSI port ratio is allowed for
each survivable Port
Network.
If the ATM is remote to the
Port Networks, an IPSI is
required in each survivable
Port Network.
No changes are needed for
an IP Connect
environment.
Install an IP Media
Processor and an IPSI
board in every survivable
Port Network.
