i have some queries regarding RRI
and Flexi hopper
1. at max. how many E1 we can send through one Flexbus of RRI
2. During Allignment the voltage which we get in multimeter, what relationship does it have with the RSL Level(dBm) which see in FXC RRI- Measurements in NOIKIA HUb Manager
Please inform me of the above queries!!!!!!!!!1

hi mukul goo dto see ur mess.
there are 32 E1 which can be carried by one flexihopper.
sorry mukul i don’t have the ans. right now i’ll try to get that
till then good bye15th November 2005 at 07:53 #42864ATULGuest
mukul, i am also working on nokia systems. well, i beg to differ with shaleen on his answer. actually its not correct. u can at the max bypass 16 E1’s thru one rri flexbus.16th November 2005 at 13:30 #42865patrickGuest
i know RRI on citytalk, max is 4E1
But on the nokia ultrasite documentation, the max of FXC RRI is 16E118th November 2005 at 14:21 #42866MUKUL CHAINANIGuest
thanXS FOR REPLYING ACTUALLY I ALSO HAVE COME TO CONCLUDE THAT ! RRI flex bus can transfer 16 E1s
can u pls tellme in FIU19E
we can haVE THREE PLUGIN UNITS
EACH WITH Four RJ45 INPUT PORTS
AND THERE ARE 2 FLEXBUS
SO HOW MANY E1 THIS FLEXBUS OF FIU CAN SUPPORT?
CAN U PLEASE TELL ME THE ANSWER OF MY SECOND QUERY IN THE PREVIOUS MAIL…
waiting for ur reply

i really apologize for my wrong ans.
actually i had asked this from one engg. who is on contract basis with NOKIA he is from philipines.
he had given me that answer.
BUt one thing i want to quote
might be that flexihopper radio has a capacity of 32 channels but the equipments which we use like RRI card and FIU19E
they have the limioted capacity of 16
as mukul has quotted about the FIU
it comes out to be 16 again.21st August 2007 at 07:49 #42868jacobGuest
you know that in fxc rr1 unit the max. e1 depends upon the rf plan for that site. it mains if the plan is 16 e1 the number of links will depend upon the fxc rri but sometimes 16 channel cant be use, they are allocating only perhaps 13 channel for the other link.
2. the rsl and dc reading is synchronized for both of them.
the rsl is in dbm while in voltmeter is volts, it means the ratio will determine if what label you have for example -41dBm=3.++ something ok
