Computer components

The BCM1000 computing functions are supported by the following hardware:

•memory: 256 MB SDRAM; 128 MB SDRAM added for 2.0 upgrades.

•hard disk: 20 GB hard disk (2.5 hardware); 8.4 GB hard disk (2.0 hardware)

Software version note: Systems running software more recent than BCM 2.5.1 require a

20 GB hard disk with specific partitioning. Refer to the upgrade guide accompanying any software upgrade for specific system requirements.

•four PCI slots containing one MSC and four possible combinations of WAN, LAN, and/or modem cards

•four PEC slots on the MSC, each of which can contain one Processor expansion card (PEC) I or PEC III (2.5) (basic 2.5 systems are delivered with two PEC III cards)

IP telephony note: The IP telephony feature requires PEC IIIs.

Hardware components

The main component of the Business Communications Manager system is the BCM1000. This hardware controls all data and telephony tasks, such as call processing, voice messaging, and data routing.
