Procedure 2
Determining the number of carriers required
Step

Engineering examples
Engineering examples are developed to illustrate the procedure described
above. They cover only traffic capacity issues specifically associated with
Carrier Remote IPE engineering.
Given the number of carriers, find allowed ports and required
enclosures. Example 1: Three T1 carriers are provided to serve a
Carrier Remote IPE. All ports are lines with 6 CCS each.
Find the maximum number of lines three T1 carriers can support.
1.
From
can be handled by three T1 carriers is 1665.
2.
Divide CCS by 6: 1665/6=277. Traffic generated by 277 lines at 6 CCS
each can be supported by three T1 carriers.
Action
Multiply the number of lines by CCS per line, the number of trunk
by CCS per trunk, and so on, and total them to obtain the total
traffic offered to the carrier.
Refer to Table 5 "Carrier capacity calculations" (page 39)
the T1 or E1 column to find the CCS number greater than the
calculated number, and find the corresponding carrier number to
determine the number of carriers required.
If no number in Table 5 "Carrier capacity calculations" (page
39) is large enough to cover the calculated number, it means that
the given configuration and traffic is too large for three carriers.
Reduce the number of ports, or the CCS per port, or both. The
resulting number has to be less than the entry from
"Carrier capacity calculations" (page 39)
handle the given configuration.
If traffic and number of lines have to be maintained, multiple lines
of carriers and cabinets will be needed.
Use only columns with 1 or 2 carriers in
calculations" (page
The port counts in the final configuration should be within the
slot limitation of the Carrier Remote IPE enclosure (16 for IPE
module, 10 for the Main Carrier Remote IPE cabinet and 6 for
the Expansion Carrier Remote IPE cabinet).
