!
CAUTION:
CAUTION:
Issuing the commands below will cause a service interruption. When Port 
Networks switch to either a Main server or ESS server a level 2 restart is initiated 
on the Port Network. Service will be interrupted to the entire Port Network. Note 
that shuffled IP to IP calls will not be dropped but during the restart they will not 
have any access to features (Hold, Transfer, Conference, etc.). 
7. When the Main media server(s) and network are operational and stable, schedule or 
initiate an on demand switch back of Port Networks to the Main. At the Main use these 
commands:
Note:
Note:
ATM PNC
When a Port Network, that is providing control for other sub-tending Port 
Networks via an ATM Expansion Interface (ATM-EI) circuit pack switches to a 
media server, the other sub-tending Port Networks may or may not end up being 
controlled by the same media server. All IPSI controlled Port Network(s) in the 
configuration will vie for control of the sub-tending Port Networks. The only way to 
guarantee that ATM-EI controlled Port Networks will be controlled by the same 
media server is if all IPSI controlled Port Networks are controlled by that same 
media server. 
Schedule a switchback to the Main with the change system-parmeters ess 
command. See 
on page 19 for more information. 
The Auto Return field may be set to scheduled or no. If no is used the only way to 
initiate a switch back is via an on demand command (See below). The 
system-parameters ess administration screen may be displayed at all ESS 
servers but may only be changed at the Main server. 
Initiate an on demand switch back by using the get forced-takeover 
ipserver-interface port-network 
command. Note that this command may 
be issued with a qualifier for all Port Networks or a single individual port-network 
N
.
b. Error Type 257: This error applies to a Main or ESS media server. 
This error is generated when an ESS server is translated on the Main but is NOT registered 
with the Main.
