According to the customer : the average traffic for trunk module is 0.8E/DTM, Every
call duration is 90s,So the traffic for every module is:
0.8E*3600*30tks/CE=960BHCA/CE

3. Traffic calculate
3.1 Test identity 1: normal traffic: 0.8E/ DTM line,90s call duration, 960BHCA/DTM
we use 2600 DTM ,create traffic 1,248,000 BHCA
Investigate IPTM or HCCCSM behavior
(1). For TUP-----TUP call
8 message /call( e.g 3SAO, NO COT), average length is 20 BYTE(?) 0.8E/DTM, The call hold time is 90s
So: the number of Calls on MGTS1 (LIC1—8) and MGTS 2(LIC1—8)
is 3600*0.8*50*30CICs
-------------------------------- = 48.000 N7(TUP) calls 90
The number of MSU/Sec on MGTS1(LIC1—8)and MTS2(1—8) is:
48,000*8/3600= 107MSU/sec ,so equal 107*20=2133bytes/sec
the traffis on IPMN7 or HCCSm is 2133*8/64000=0.27 E
(2) For ISUP—to ISUP call
The average length for ISUP call is 25 Bytes
So the link MGTS1(LIC9-LIC14) and MGTS2 (LIC9—LIC14) Traffic is 64MSU*25*8/64000=0.2E
(3) For TUP—to ISUP call
the average length of TUP call is 20 bytes , the average length of ISUP call is 25 bytes
the traffic of MGTS1 (LIC15—LIC16),MGTS3 (LIC1—LIC4), carry the TUP traffic
the number of N7 calls is 0.8E*3600*30*30/90=28,800 calls
so the MSU on per link is 28,800*8/3600=64MSU/s
the traffic on these link is 64*8*20/64000=0.16E
the traffic on ISUP call links MGTS2(LIC15—LIC16), MGTS4(LIC1—LIC4) is 02E as the situation (2) is 02E
(4) For ISUP—TUP call the average traffic on MGTS3(LIC5—LIC10 is 0.2 E the average traffic on MGTS4(LIC5—LIC10 is 0.16E
(5) FOR TUP—R2—R2—TUP call
the average traffic on MGTS3 (LIC11—LIC13) is 0.16E the average traffic on MGTS3 (LIC11—LIC13) is 0.16E
(6) FOR ISUP—R2—R2—ISUP call
the average traffic on MGTS4 (LIC14—LIC16) is 0.2E the average traffic on MGTS4 (LIC14—LIC16) is 0.2E
3.2 At overload situation : 2,000,000BHCA carry on Exchange
For to get the load, we need to more traffic: 2,000,000-1,248,000=752,000BHCA
we need to add al these traffic to NTUP_NTUP,ISUP_ISUP, NTUP_ISUP,ISUP_NTUP call
SO: we need to add more traffic to every DTM is: 752,000/(400+180+180+180)=800BHCA/DTM
SO every trunk module now carry: 800+960=1760BHCA/DTM
(except DTM that interworking with R2)
Now : every call duration is: 3600Ss*30tks/DTM*0.8E/DTM/1760=49s
SO; we assume every call duration is 48s: we create traffic on these DTM is :
940*1800=1,692,000BHCA
we add the traffic the Interworking with R2: 360*960BHCA/DTM=345,600BHCA
Now the traffic on whole exchange is : 1,692,000+345,600=2,037,600BHCA
Investigate IPTM or HCCCSM behavior
(1). For TUP-----TUP call
8 message /call( e.g 3SAO, NO COT), average length is 20 BYTE(?) 0.8E/DTM, The call hold time is 90s
So: the number of Calls on MGTS1 (LIC1—8) and MGTS 2(LIC1—8)
is 3600*0.8*50*30CICs
-------------------------------- = 90.000 N7(TUP) calls 48
The number of MSU/Sec on MGTS1(LIC1—8)and MTS2(1—8) is:
90,000*8/3600= 200MSU/sec ,so equal 200*20=4000bytes/sec
the traffis on IPMN7 or HCCSm is 4000*8/64000=0.50 E
For the N7 link traffic Didn’t above 0.4E ,we assume that every N7 call has 6 MSU(only one SAO)
thus: we have 90,000*6/3600=150MSU/s
so the traffic on per link is: 150*20*8/3600=0.375E/per link
(2) For ISUP—to ISUP call
The average length for ISUP call is 25 Bytes
So the link MGTS1(LIC9-LIC14) and MGTS2 (LIC9—LIC14)
Traffic is 3600*0.8*30*30/48=54,000N7calls(ISUP) Euqal 54000*8/3600=120MSU/S the traffic on per link is 120MSU*25*8/64000=0.375E
(3) For TUP—to ISUP call
the average length of TUP call is 20 bytes , the average length of ISUP call is 25 bytes
the traffic of MGTS1 (LIC15—LIC16),MGTS3 (LIC1—LIC4), carry the TUP traffic
the number of N7 calls is 0.8E*3600*30*30/48=540,000 calls
so the MSU on per link is 540,000*8/3600=120MSU/s
the traffic on these TUP link is 120*8*20/64000=0.3E
the traffic on ISUP call links MGTS2(LIC15—LIC16), MGTS4(LIC1—LIC4) is 0.375E as the
situation (2) is
(4) For ISUP—TUP call the average traffic on MGTS3(LIC5—LIC10 is 0.375E the average traffic on MGTS4(LIC5—LIC10 is 0.3E
(5) FOR TUP—R2—R2—TUP call ,traffic is no change
the average traffic on MGTS3 (LIC11—LIC13) is 0.16E the average traffic on MGTS3 (LIC11—LIC13) is 0.16E
(6) FOR ISUP—R2—R2—ISUP call, traffic is no change.
the average traffic on MGTS4 (LIC14—LIC16) is 0.2E the average traffic on MGTS4 (LIC14—LIC16) is 0.2E
