Reference no: EM13329153

An E1 is the European version of our T1. An E1 frame has 32 channels. The first channel is channel 0. All 8 bits of channel 0 are used for framing. Channels 1 to 15 are used for data or voice and no bit robbing is used or needed. Channel 16 is used for control information on all the voice and data channels. Channels 17 to 31 are also for voice or data.

a. How many channels are overhead?

b. How many channels can be used to send data?

c. What is the overhead and the through put for an E1 frame?

d. Using the magic number, what is the total data rate used to send E1 frames?

e. What is the data rate for the users information?

f. How many framing bits are sent in one second?
