Overview of NBX
Cards and Devices
This section lists all of the NBX devices that can be used with either the
SuperStack 3 NBX or the NBX 100 system. Not all cards may be available
in every region.
Before you install any Analog Line Cards or Digital Line Cards, you may
want to configure the Dial Prefix settings. For information on this topic,
see “Dial Prefix Settings” in Chapter 2 in the
NBX Administrator’s Guide or
the NBX NetSet Help at Dial Plan > Operations > Dial Prefix Settings.
Analog Line Card The NBX Analog Line Card connects up to four analog telephone lines to
the NBX system. The SuperStack 3 NBX system can support up to 180 line
cards (720 CO telephone lines) using multiple NBX Gateway chassis. The
NBX 100 system can support up to 25 line cards (100 CO telephone lines)
using multiple NBX 100 chassis.

Figure 7 NBX Analog Line Card (3C10114C)
Functionally, 3C10114 and 3C10114C are identical. However, 3C10114C
uses some different internal components so that 3C10114C requires NBX
software release R4.1 or higher.
Each Analog Line Card contains the following lights and connectors:
■
Status Lights (1 through 4) — Each light shows the status of the
associated line.
Initialization (prior to Release R4.1):
■
All four lights flash in unison – Hardware is initializing.
■
A light flashes on twice, off for 2 seconds – Associated port
has been initialized successfully.
