Option 11C and 11C Mini Technical Reference Guide
• 80 conferees when equipped with three Fiber Expansion Link
• 96 conferees when equipped with four Fiber Expansion Link
For the Option 11C Mini, the MSC provides 16 channels of conferencing with
a maximum of six conferees per conference call on conference loop 29. This
allows for up to five simultaneous three-party conferences and up to two
simultaneous six-party conferences.
TDS loops
Option 11C has been engineered such that a single SSC card, SSC, or MSC,
with 30 channels of TDS. This should be enough to meet all TDS
requirements.
To illustrate this point, two examples are given below.
Example 1
Option 11C configured with two expansion cabinets provides 30 slots for
trunk and line cards.
The SSC card can support 7260 CCS of call traffic. A digital line card
supports 16 units per card. A Universal trunk card supports 8 units per card.
The CCS per card would be:
Assume the following:
• An average station generates 6 CCS of traffic
• A 20 percent trunking ratio
• An average trunk generates 22 CCS of traffic.
Digital Line card 16 Units/card x 6 CCS/Unit = 96 CCS/card
Universal trunk card 8 units/card x 22 CCS/Unit = 176 CCS/card
