“Configuring nailed channels”
on page 7-21
You must assign a nailed channel to a
group to make it available for use. The
group number can be referred to in a
Connection or Frame-Relay profile to
specify a permanent leased connection
using that group of nailed channels.

“Configuring a back-to-back T1
connection” on page 7-21
For diagnostic purposes you might
sometimes want to configure a
back- to-back connectionT1 connection
between ports on two TAOS unit units.
Signaling-Mode set to Inband (the
default)
Robbed-Bit-Mode set to

“Specifying analog encoding for
TAOS unit codecs” on page 7-22
Codecs connected to T1 use a different
encoding standard for digitized analog
data than do codecs connected to E1.
The default for T1 is U-Law, the default
for E1 is A-Law.

“Configuring specialized
options” on page 7-22
Typically, the D channel of a PRI line
uses normal data. However, for some
connections, you might need to invert
the data to avoid transmitting a pattern
that the connection cannot handle
Most installations use the default for the
Idle-Mode setting, which determines
what pattern the D channel looks for to
specify the idle indicator.

Chapter 19, “Configuring Call
Routing”
The TAOS unit uses call routing to
determine where to route incoming and
outgoing calls. The preferred way to set
up call-routing is to put all call-routing
information in one place: a Call-Route
profile.
If you do not use Call-Route profiles,
specify the physical address of a device
to which calls received on this channel
are routed.
