Quantity of each card to be employed in the exchange is calculated similarly. After that, the
number of the card slots that is needed is calculated. The following information would be
critical for that calculation:
1) One must keep in mind that two slots for each of the PRI and R2 cards is to be used.
2) An extension card is supposed to be installed in the first slot of the exchange.
Once the number of the card slots that is to be used in the exchange has been calculated,
then one can decide about the type of the exchange:
-
If the number of the slots is less than 9, then DS200M can be employed.
-
If the number of the slots is between 9 and 14, then DS200S can be employed.
-
If the number of the slots is more than 14, then DS200 is supposed to be employed.
-
Number of racks that would be needed while the number of the slots is more
than 14: This can be calculated by rounding the outcome of the ratio “Number of
slots / 14” to the greater integer.
-
If the number of the slots is less than 28, then wall-type installation with one or
two racks can be performed.
-
If the number of the slots is more than 28, then cabinet-type installation should
be carried out.
-
Number of cabinets that would be needed can be calculated with respect to
the number of the racks to be employed.
-
If 1, 2 or 3 racks are needed, then a three-rack cabinet,
-
If 4 racks are needed, then a four-rack cabinet,
is supposed to be employed.
