Migrating X.25 over PSI to X.25 over TCP/IP (XOT)

8 Benefits of XOT against PSI
Following are the advantages of using XOT instead of X.25 over PSI card:
Lower hardware cost
• Ethernet cards cost less compared to PSI cards. Moreover, the extensive use and large demand
for Ethernet cards are expected to lower the cost of Ethernet cards.
Lower operational cost
• The administration, management, and maintenance costs involved in implementing XOT systems
with Ethernet cards are significantly lesser than the costs involved in implementing X.25 over
PSI.
• Skilled TCP/IP network administrators are easily available in contrast to administrators with
working knowledge of X.25 over PSI. This reduces the total cost of ownership.
Higher performance
Tests show that X.25 applications perform better on XOT protocol stack than on X.25 over PSI
protocol stack.
NOTE: Currently, there is no SAM support for XOT configuration. The X.25 configuration files
are edited manually. The X.25 interface must be started and stopped manually.
