i need to know number of E1 needed to connect remote BSC with MSCS and number of E1 needed for SS7 signaling4th May 2008 at 11:34 #52313pixGuest
it highly depends on the traffic you’ll carry in the BSC.
4 E1 = 123 channels + 1 SS7 timeslot
then you can use your erlang B table to find out how much channels you need to carry your traffic.
the SS7 uses usually 1 timeslot for 4 E1 (typical configuration rule, a little over-dimensioned though)
If you need 20 E1, then you’ll need 5 SS7 timeslots.4th May 2008 at 12:00 #52314mosaGuest
but in full configuration what number of E14th May 2008 at 12:59 #52315pixGuest
oh, ok, THE full configuration. Well, I’ve no idea about THE full configuration of your BSC, because the full configuration of a Huawei, Ericsson, Alcatel, Nokia, Motorola, ZTE BSC’s are all different.
As said earlier, it depends on how many TRX will be connected to the BSC.7th May 2008 at 05:25 #52316mosaGuest
if i have siemens bsc what number of E1 in full configuration7th May 2008 at 07:15 #52317pixGuest
good morning mosa,
sorry, i can’t help you on this one. it is dependent on Siemens specs, but if you can tell me how many TRX are connected to your BSC in full config, i can give you a rough idea of how many E1 you’ll need.
I can’t do anything more 🙂

how much erlang carry a E1 and a ter link?25th June 2008 at 15:21 #52319pixGuest
1 E1 of the ATer can carry 30 x 4 calls = 120 calls simultaneously.
the capacity = 120 channels. check your erlang B table to have the amount of erlangs. It should be about 115 to 119 erlangs.29th May 2011 at 02:29 #52320Abdullah Al MamunGuest
How much TRX will be support for a E1?
