E1 is carried inside C-12 container in SDH enviroment. Size of container is bigger than payload requirment of E1 in order to have clock alignment, justification opportunity bits, justification control bits, & overhead bits. C-12 container is 272 bits which multplies with 8000 (frames per second) to get data rate for one C-12 per second. Multiplying it with 63 will give you 137.088 Mbps.
How many different ways can you make $3.25 in math
A 1000grams make a killogram.
It's not.-- The E1 line rate is 2.048 Mb/s.-- The data rate of 63 E1s, simply time multiplexed, would be 63 x 2.048 = 129.024 Mb/s-- 64 E1s may be multiplexed into a single E4 stream, at a rate of 139.264 Mb/s.-- The STM1 data rate is 155.52 Mb/s. Any combination of data streams totalingroughly that rate, including as many as perhaps 75 E1s, could be packaged fortransport on an STM1 facility.

1E1=2.048MbpsSTM1=63 E1...AND STM4=4*STM1=63*4E1sbUT ITS NOT THAT EASY...In SDH there is a lot of header data...STM1 =155.52MbpsSTM4=622.08MbpsSTM16=2488MbpsSTM64=9953Mbps....

E1s mean more E1 channel,for example,2E1,4E1,8E1,16e1 etc
One STM-4 support Maximum 268 E1's.

in GE interface the STM-1 can carry 155 Mbps but on SDH it will carry 142 Mbps

STM-1 stands for Synchronous Transport Module level-1....:)
Hai, first STM stands for (Synchronous Transport Modules) it is nothing but the bandwidth Throughput, STM1 = 155.52Mbps there for for STM4 = STM1 * 4 ie = 155.52 * 4, there fore STM4 = 622Mbps, Thanks & Regards Ashok Sriram DEN NETWORKS BANGALORE
He uses the Ibanez STM1 in white and black color. And he uses an STM2 in color blue.
