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 totaling
roughly that rate, including as many as perhaps 75 E1s, could be packaged for
transport on an STM1 facility.
In mapping of PDH Signals into SDH is true.
SDH supports only 63 E1 ports for STM-1.
63 feet is equal to 21 yards. Remember that there are 3 feet in each yard, so 63/3=21

There are 0.0254 metres in one inch. Therefore, 63 inches is equal to 0.0254 x 63 = 1.6002 metres.
160 cm = 160/2.54 jnches = 63 inches
If you think to isoprostane see the link below.

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.
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.
In sdh radio 63 E1's are there
There are 63 E1 in one STM 1

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
63%
63 has a square factor, but no equal ones.
