BHCC capacity for S8700 Media Server

The following is information about busy-hour call completion (BHCC) capacities for the S8700 Media Server. The values are based on current available data and may change as more data becomes available.

S8700 Media Server, light call mix--100% analog station-to-station

• 300,000 BHCC
• 250 Media gateways
• 36,000 - analog stations
• 8,000 trunks.

S8700 Media Server, general call mix--analog,
DCP stations, and PRI trunks

• 220,000 BHCC

• 12,000 IP endpoints
• 450 IP endpoints per CLAN board.

S8700 Media Server and contact center--analog,
DCP stations, and PRI trunks

• Low contact center usage--75,000 BHCC (low = simple vectors, minimal skill level use; skills-based routing is under High)
• Typical contact center usage--40,000 BHCC
• High contact center usage--25,000 BHCC (high = pre-routed calls, BSR with many skill levels, heavily linked vectors, long speed to answer and many different announcements).

NOTE: Any configuration that includes IP Solutions applications such as Road Warrior, Telecommuter, or H.322 trunking, affects the BHCCs and processor capacity. If a customer uses these applications in a high traffic solution, it is recommended that the Avaya Technology and Consulting (ATAC) team be involved to review any potential impact on traffic.

The information in this table represents the maximum number of calls the S8700 Media Server could execute, assuming it was unconstrained by other factors such as:

• TDM bus limitations
• Call duration
• Small number of telephones

We assume processor occupancy of 0.90, at which various delay criteria such as cut through is preserved, and is just at the threshold where call could no longer be processed.
