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

in 1stm how much bandwidth
The bandwidth of STM-64 (Synchronous Transport Module level 64) is 10 Gbps (Gigabits per second). It is part of the Synchronous Digital Hierarchy (SDH) standard used in telecommunications for high-capacity data transmission. STM-64 can carry multiple lower-rate signals, making it suitable for backbone networks and high-speed data applications.
STM-4 have the data rate 622.08Mbps. And STM-4 support 269 E1's.
One STM-4 support Maximum 268 E1's.
STM-0= 21 E1 lines STM-1=(64x1) - 1 = 63 E1 lines STM-4=(64x4) - 4 = 252 E1 lines STM-16=(64x16) - 16 = 1008 E1 lines STM-64=(64x64) - 64 = 4032 E1 lines and so on
There are 63 e1's in sdh STM-1 = 63 x E1; STM-4 = 63 x 4 E1; STM-16 = 63 x 16 E1; STM-64 = 63 x 64 E1.
A lot
Synchronous Transport Module (STM) currently has levels 1, 4, 16, 64, 256 and 1024 where each level corresponds to a specific bit rate. The STM frame is considered as the basic transmission format for the Synchronous Digital Hierarchy (SDH) technology. These STM frames are byte-oriented arranged in a row and column manner.
It can. 167 Mbps of user's business traffic on a single duplex carrier is quite common now, as are several higher data rates.
stm is stand for socaiety transportation of Montreal
There are 63 E1 in one STM 1
