Configuring T1 Cards
Overview of T1 configuration
“Configuring inband robbed-bit
signaling” on page 7-11
If the lines use inband signaling, change
the signaling mode to robbed bit and
specify the type of robbed bit signaling
to use. You can also specify that the
TAOS unit process the numbers dialed
for use with Dialed Number
Identification Service (DNIS) and
Calling Number Identification (CLID)
authentication.

“Configuring NFAS” on
page 7-13
Specify non-facility associated signaling
(NFAS) if you want two or more PRI
lines to share a D channel.

“Configuring T1 R1 and
R1-Modified (Taiwan) with ANI
and called-number processing”
on page 7-15
R1 is a multifrequency inband signaling
system that uses a set of register signals
known as MFR1 tones as addressing
signals. R1 signaling can optionally be
used with Automatic Number
Identification (ANI), which is similar to
Caller ID (CLID).

“Configuring clocking” on
page 7-17
Set Clock-Source to specify whether the
T1 line can be used as the master clock
source for synchronous connections.
Also specify the priority of the T1 lines
to be used for clocking.

“Configuring the front-end
transceiver” on page 7-17
Set the front-end type of the T1
transceiver to CSU (channel service
unit) or DSX (digital signal cross
connect), depending on the type of
device the TAOS unit connects to.

“Configuring channel usage” on
page 7-18
Specify how each of the 24 channels of a
T1 line is to be used.

“Assigning telephone numbers
to switched channels” on
page 7-19
Typically, you specify only the
rightmost digits necessary to distinguish
one number from another. These are
called add-on numbers.
Phone-Number
“Configuring trunk groups” on
page 7-20
A trunk group is a group of channels that
has been assigned a number.
