How to calculate the the capacity of access lines on G-bit ethernet if you need to service “n” PC’s on this access line? Used protocol-IP.
What is effective speed of users data on G-bit ethernet if the number of users raise?7th June 2003 at 15:40 #33376germoGuest

wanted to know the formula behind the extended erlang b which takes into account the retrials.
how different isit from erlang b24th July 2003 at 05:49 #33380praveenGuest
GOS or grade of service is nothing but how many calls are remaining without obtaining signalling setup ,out of 100.If 4 call attempts are being failed due to set up problem then GOS will be 4 % .28th July 2003 at 14:17 #33381luz adriana Infante LaraGuest
I want to know, What is the relation between ASR y GoS?
Thanks.29th July 2003 at 06:39 #33382MuzammilGuest
ARS (Automatic Routing Selection), is the routing table, tells the switching system or PBX where to route the call depending on the numbers dialled. Say, if routing says block all calls with 00%, It will block all the international calls.
Where as GoS (Grade of Service) is the service level offered by an operator. Say, an operator has P.02 GoS, means two calls fail out of 100 simultaneous call attempts.

i think what adriana means is ASR or answer-seizure ratio, i dont know, but they are somehow related, if you have low ASR, meaning you get very poor completion of your calls, it means you have high GoS, lots of congestion etc., and vice versa, inversely proportional i would say4th October 2003 at 00:34 #33384NRGuest
What is the corelation between TRXs and voice channels? For e.g. if I have 6 TRXs does it mean, I have 6 lines?? Then based of the 6 lines, can I back out the total busy hour erlangs I can support for a given GOS??
Thanks for the help,

In a GSM technology, what is the preferred GoS, is it 1% or 2%?11th November 2003 at 11:47 #33386v.sriramGuest
can you send me the excel of GOS matrix.
my id is firstname.lastname@example.org
thanks in advance11th November 2003 at 14:24 #33387JuliusGuest
A GoS of 2% is preffered in TCH traffic channel while that of 1% is preffered to SDCCH signalling channel,
And i think it is important to note that GoS is the Probability of Blocking and not Call drop after the setup phase.

Does anyone have a document explaining reasons for SDCCH drops on ABIS? (Not the usual timeouts)
also can anyone pls mail me the formula for TCH assign Success Rate?

I am Rudyno, third grade
student of electrical engineering from University of
Indonesia. I have a problem about switching design
course. The problem is to design configuration of a
switching network by using space switch. Which is
serve 50 subscribers with calling rate 0.05 erlang,
interoffice connection 0.2 erlang,and the rest for
outgoing. Please give me the hint to solve it,
especially about the interoffice connection. What does
it mean? I am sorry if there are many mistakes in my
words. Thank you very much.
