Administering the ATM Switch
To administer the ATM switch, refer to your switch’s quick reference guide. 
Administering DEFINITY ECS
The DEFINITY ECS switch software provides 2 kinds of ATM service: 
nATM Por t Network Connectivity (ATM-PNC)
nATM Circuit Emulation Service (ATM-CES)

Ta b l e  3 outlines important concepts to observe when administering ATM.
ATM Port Network Connectivity (ATM-PNC) 
Each DEFINITY port network must be translated in the PPN’s screen with the full 
ATM address (The ATM switch prefix, plus the port network’s ESI, plus a Selector 
of 0) that uniquely identifies it.
Use the procedure in Ta b l e  4
 to administer ATM-PNC:
