Card capacity depends on the software release, test requirements, path confirmation type and hardware. The most accurate numbers can be found in the hardware datasheets located at https://www.spirent.com/Solutions-Directory/Abacus.aspx (Document tab). For example, if you want capacity information regarding SIP, look in the ICG datasheet. If you have the Abacus GUI software installed on your PC, you may also find capacity information in the release notes located in you manual folder (Example: C:\Abacus 5000\6.10\MANUAL).
