Versatile Interface Processors (VIPs)

• VIPs hold can contain 2 port adapters with either IP or SS7 media interface

• While capable of containing a mix, recommended deployment is not to mix port adapter types for performance reasons

Link Calculations per VIP

• VIP LSL Capacity: 4096 MSUs IN and 4096 MSUs OUT• DS0=64kbps (64000bps/8 = 8000 bytes/sec)• Fail over at .6E. 8000 x .6 = 4800 bytes• Average MSU size is 120 bytes• 4800 bytes / 120 = 40 MSUs/Sec/Link• 4096 MSUs/sec Divided-by 40MSUs/sec/link

6000/40 = 102 Links
