nIntend is that these capabilities will provide administrators with an 
enhanced ability to isolate, diagnose, and correct problems quickly.
Bandwidth Constricted Network 
Example
nCurrently, when a call is to be extended between PNs distributed over an 
ATM network, a CCMS message to provide ringing at the destination is 
sent after the actual SVC setup, but before the SVC...

nIf all appears normal in the error log, but the latencies are too high, may 
need to upgrade the ATM network to solve the problem. 
NOTE:
fter the problem is fixed, the alarm will clear, but it will take an indeterminate 
amount of time.
nThe ALARM REPORTING OPTIONS form is displayed via the set options 
command.
nThe Off-board ATM Network Alarms field appears regardless of...

nThe Port is deciphered as: ATxy. 
— xy is the connection number, not the port network number. 
nThe mapping between connection number and port network number can 
be found with the command list atm pnc. 
nThe Aux Data field contains the originating/ destination port network 
numbers. 
— The rightmost two digits are the destination port network number. 
— The remaining leftmost...

Example
nThe Err Type field is the value 256+destination connection #. 
nThis allows multiple entries of the same port name/ Mtce name pair in the 
error log. 
nIf the error type value was the same for a given port name/Mtce name pair, 
only get 1 entry for that port name/Mtce name pair in the error log. 
nUp to 6 entries of the same port name/Mtce name pair can be stored in...

nThe mapping between connection number and port network number can 
be found with the command list atm pnc. 
nThe alarm indicates that at least one path originating from the displayed 
Por t, has exceeded the SVC setup threshold. 
nThe alarm is resolved when SVC setups from all paths...

T1 401A/E1 402A/E1 403A Synchronization 
Splitters
A DEFINITY ATM-PNC requires network synchronization for DS1 circuit packs not 
to slip relative to the LEC/IXC switches. The ATM switch serves as the sync 
reference source for the DEFINITY. The ATM switch, in turn, derives primary and 
secondary sync. To accomplish this, the most common option is to use 
synchronization...
