Q. 1. Telephone Companies use a hierarchy of Digital Signals Service (DS) which have different levels as DS-0, DS-1, DS-2, DS-3 and DS-4. All these levels have different data rates and are implemented through different types of T lines (from T-1 to T-4) or E lines (from E-1 to E-4) on the basis of data rate in each level.
Now you are required to fill the columns of the given table according to following instructions:
Note: Type of line (form T-1 to T-4 or from E-1 to E-4 line) and total number of T or E lines must be selected on the basis of calculated data rate having minimum wastage of capacity of the line. Only optimal solution is required for these columns.
Q. 2. Using Modulo-2 Division and Polynomial x4 + x3 + x + 1, perform the complete process of Cyclic Redundancy Check (CRC) on the given message by writing all steps for both sender and receiver end.
Assume that the message has been received by the receiver without any error. [15 Marks]
asif sahib yeah taheek ha na upload ker dain
very thx Asif Bhai MCS for improving the assignment
plz tel me how u find T /E lines are using?And how calculate data rate .what overhead is also added ?plzzzzzzzzzzzzz explain
thank u so much Asif. abhi work itna tha k is assignment par kam krna bht mushkil hota.
Thank you Bro.
I just want take the concept how did you Draw the Division. and seen from your document but i didn't copied.
Once Again Thanx Brother.
Instruction about Assignment No.4
|Dated: Jan 24, 13|
In assignment no. 4, while selecting T or E lines, there is no need to include any overhead in the table although we have used it in handouts but you are not required to include it. You are just required to select T or E lines on the basis of calculated data rate (without including overhead).

data rate find kerny k steps kya hongy?
Steps for Data Rate Calculation:
So in this way you can calculate Data Rates.
