The following sections describe how to add a T1 Digital Line Card
(3C10116C and 3C10116D) and how to connect to a T1 service provided

Installation Notes
An NBX 100 system can accommodate up to 3 T1 Digital Line Cards; a
■
SuperStack 3 NBX system can accommodate up to 30 T1 Digital Line
Cards.
You can choose to configure a T1 Digital Line Card to use one of two
■
types of signaling:
DS1 protocol (sometimes called Standard T1). By default, the Auto
■
Discover process selects DS1 as the signaling type.
ISDN PRI (Primary Rate Interface) signaling.
■
The 3C10116D T1 Digital Line Card can be installed at a remote
■
location and communicate with its NCP over a routed network. For
information on how to set up a remote T1 card, see the NBX
Administrator's Guide.
Before you install any T1 Digital Line Cards, you may want to
■
configure the Outdialing Prefix settings. For more information, see the
Dial Plan chapter of the NBX Administrator's Guide.
For IP operations, a 3C10116D T1 Digital Line Card must have either a
■
static IP address or get its IP address from DHCP. 3C10116D T1 Cards
cannot use the NBX IP On-the-Fly feature.
3C10116D T1 Digital Line Cards do not support DHCP lease times of
■
less than 20 minutes.
