Provisioning
The 30 card slots available can support a system configuration of 384 lines
(24 line cards) and 48 trunks (6 trunk cards). The total CCS for this
configuration will be:
(24 line cards) and 48 trunks (6 trunk cards). The total CCS for this
configuration will be:
Total CCS: (24 line cards x 96 CCS/card) + (6 trunk cards x 176 CCS/card)
= 2304 CCS + 1056 CCS
= 3360 CCS
= 3360 CCS
If the number you receive is greater than one, you can add an NTAK03 TDS/
DTR card to the system.
DTR card to the system.
Example 2
A system that is more heavily trunked, say a one to one ratio, can support a
configuration of 192 lines (12 line cards) and 144 trunks (18 trunk cards):
configuration of 192 lines (12 line cards) and 144 trunks (18 trunk cards):
Total CCS: 12 line cards x 96 CCS/card + 18 trunk cards x 176 CCS/card
= 1152 CCS + 3168 CCS
= 4320 CCS
= 4320 CCS
The SSC card, at 7260 CCS, still provides plenty of TDS capability.
Calculating memory requirements
Use “Worksheet D: Unprotected memory calculations” on page 141
and“Worksheet E: Protected memory calculations” on page 142 to calculate
memory requirements. Use the two-year figure for telephones, consoles, and
trunks for the calculation. Add 10 percent to the total memory requirements.

Assigning equipment and preparing equipment summary
Use “Worksheet F: Equipment summary” on page 143 to record the
equipment requirements for the complete system at cutover. Assign the
equipment. The equipment summary may have to be updated as a result of
assignment procedures. Use the finalized equipment summary to order the
equipment for the system.

Calculating battery backup time
Use this procedure to determine:
•
system power consumption
•
battery current for customer-provided DC reserve power
