Help,
Is the formula to convert traffic to erlangs for ss7linkset?
(say for the entire day)
(8 * (sifsio + (6 * MSU))
————————
(duration) * data_rateduration = endt – strt in seconds
data rate = ss7 link data rate????Can anyone comment on this?
Adel KhaderGuestThis formula is valid for 64K Signalling Links and not valid for High Speed Signalling Links
data rate in this case 64000
ScotGuestHi Adel can you provide me the formula for calculating the load percentage wise.
I am recording stats by Hourly.
Rgds
Adel KhaderGuestHi Scot;
Load is calculated based on:
1) One Tome Slot can Carry maximum of 1 Erlang @ one Hour.
2) Traffic on C7 Signaling Link should be keept bellow 0.3 Erlang per Time Slot.so the formula is:
100*8*(SIFSIO+(6*MSU)
———————————–
(0.3*64000*Number of SL in LS*3600)ZeeGuestDear All
I am working in IN deptt and I have been given a task to calculate the SS7 link load
The formula that i used is
Total subscribers * (Avg BHCA/sub * AHT) / 3600 = IN load in Erlangs
Another one is
100*8*(SIFSIO+(6*MSU)
———————————
(0.3*64000*Number of SL in LS*3600)which i couldnt get
which is this the right formula?i will appreciate any suggestions or corrections
Regards
Zee

deepakGuestWhat is signalling between BTS and BSc.Can anybody guide me about this?
SachinGuestDeepak,
The link between BTS and BSC is the Abis interface. It is a 2MBPS link with 32 timeslots. Every timeslot is for 64 KBPS. Timeslot zero is reserved for signalling and the rest are available for voice and data traffic.
Regards,
SachinraghuGuesthai deepak
the signalling between bts & bsc is on LAPD. I would say that for every TRX(voice channels) u also need to reserve a channel for signalling.
type of lapd – concentration, multiplexing.e.g of lapd concentration on a PCM ts0 – sync, ts1 will e for trxc signalling and subsequent 2 ts for traffic channels 18
