Table 65: IP networking limit calculations
CALCULATION
FORMULA
RESULT
Traffic from IP sets
Number of sets (250) x 6 CCS
1500 CCS
Percentage networked
Total traffic x 15%
225 CCS
Percentage traffic intercom
Networked traffic x 35%
79 CCS
Percentage traffic trunk to PSTN
Networked traffic – intercom traffic
146 CCS
Total Number of IP trunk channels
needed
ErlangB on total IP trunk traffic (225
CCS)
13 channels (P.01)
Number of channels needed for PSTN
trunks (G.711)
ErlangB on PSTN trunk traffic (146
CCS)
10 channels (see note)
(P.01)
Number of channels needed for
intercom/internal traffic (G.729a)
ErlangB on Intercom traffic (79 CCS)
7 channels (see note) (P.01)
Bandwidth needed
(use worst case)
Number of G.711 channels (10) x 100k
+ [Total number of channels (13) –
PSTN trunk channels(10)] x 40k
1120 kbps
WAN bandwidth required
Assume with QoS so / 70%
1600 kbps
Number of channels (IP trunk) for IP
networking
Total number of channels
13 Channels
