Explain why individual ET Networks are desired by interestes aggravate flag PSTN?
The E1 length is an American flag and T1 length is an European flag of network which procure purpose to purpose digital transmission of postulates . In PSTN length a solitary copper wire is used to impel signification and postulates period in E1 and T1 networks span pairs of copper wires are used to impel and assent-to postulates
The reasons coercion using E1 and T1 networks in interestes are as follows:
a) The E1 and T1 networks are used widely coercion interestes accordingly they procure network lengths which are consecrated to signification message and procure 99.9% of bandwidth coercion most of the spell.
b)The E1 and T1 lengths can too interconnect with each other accordingly they consists of DS1 signals.
c)The E1 and T1 networks are principally used as interest lengths accordingly they can be disconnected into any association of signification and postulates transmissions .
d) The E1 and T1 lengths raise 24 calls aggravate them which makes them cheaper than purchasing 24 incongruous analog lengths , future are widely used in interestes.
Now a day abundant interestes are switching to VoIP – Signification aggravate IP accordingly they are comfortable to regular up and are of very moderate require compared to any other network lengths.
