nATM Network Duplication configurations come equipped with a simplex 
SPE complex in the PPN, duplicate connectivity over ATM to all PNs and 
duplicate ATM interfaces in each PN. 
nThe EPN configuration for ATM Network Duplication is the same as that for 
an EPN equipped for ATM critical reliability.
nDuplicated paths to the ATM WAN may be through the same ATM switch,...

nBoth an expansion control carrier and a port carrier are required in each 
EPN. 
nEach of the two TN2305 or TN2306 ATM interfaces and tone clocks are 
placed in each of the two carriers. 
nA TN771 facility test circuit pack is required in each port network of a R8r 
system equipped for ATM Network Duplication. DEFINITY® system 
software does not prevent placement of 2 ATM...

nOnce the ATM Interfaces, tone clocks, and ATM B-PNC addresses have 
been administered for all EPNs, the change system-parameters duplication 
command is issued. This brings up the DUPLICATION-RELATED SYSTEM 
PARAMETERS form. The Enable Operation of PNC Duplication? option is 
then changed to y. The option for Enable Operation of SPE Duplication? 
must remain as n.

Interworking with Bandwidth Constricted ATM 
Networks
Conserving ATM Bandwidth Introduction
This is a recommendation to allow DEFINITY® R8r systems using ATM Port 
Network Connectivity to perform optimally when bandwidth is at a premium. 
nATM bandwidth can be conserved, where possible, through optimal 
DEFINITY® resource allocation.
— Resources that can be optimally placed can...

nATM-PNC operation is the same from the DEFINITY® system perspective 
as if OC-3 is deployed end-to-end, except when traffic exceeds the carrying 
capacities of the IMA links, and contention occurs. 
— Similar to what occurs in an ATM network arrangement where IMA is 
not used but bandwidth is constricted over the ATM network when 
congestion occurs as the result of traffic...

nIntegrated announcement board resources are associated with extension 
numbers and are often triggered by vector directory numbers (VDNs). 
nR8r can be traffic engineered and administered to minimize the number of 
the expensive SVCs using existing software.
nIn a large ATM PNC system distributed over many locations, use of 15A 
announcement units may be preferable to the use...

Improved Resource Allocation
nATM bandwidth can be conserved, where possible, through optimal 
DEFINITY® resource allocation. 
— Resources that can be optimally placed can include general 
purpose tone receivers, TN750/B/C multiple announcement boards, 
and TN771 maintenance test boards. 
nR8r can support up to 10 TN750/B/C integrated announcement boards. 
— SVC connection is...

nTechnicians should consider lowering the Activation threshold, and raising 
the delay time threshold. 
nIf an ATM-IMP becomes alarmed unnecessarily, it is preferable to raise the 
delay threshold rather than raising the Activation threshold.
System Setup Alarms
nA System SETUP alarm uses the existing MO_ATM_IMP maintenance 
object. 
— Reported as either a minor type alarm or a...

nThe Off board ATM Network Alarms field will appear regardless of the 
option for ATM PNC, but will not appear if the system is a csi or si.

from minor to warning level, or vice versa.
