V3000 Analog The V3000 Analog ( Figure 1) houses the Network Call Processor (NCP),
which manages call traffic and NBX Messaging, the system disk drive and
power supply, and front panel connectors for network and external
device connectivity.
V3000 platforms come with 128 MB of memory. You must install an
optional memory upgrade to support some features. See
Table 13 on
page 60 for more information.
The 3C10600A version of the V3000 Analog is no longer available. The
system has been updated to 3C10600B. It includes a new front panel and
updated internal components. The function and the layout of the front
panel connectors and LEDs is the same for both models.
