Signaling mode
You must configure the signaling type (Sig Mode) for each T1 line.
If you set Sig Mode to ISDN_NFAS, you can also establish an interface ID or NFAS ID
number for this type of signaling. You must specify a different interface ID for each NFAS
line.
number for this type of signaling. You must specify a different interface ID for each NFAS
line.
Parameter
Specifies
Sig Mode
The signaling type for the line.
NFAS ID Num
An interface ID number for a line using Non-Facility Associated
Signaling (NFAS). Each NFAS line must have a different ID number.

Rob Ctl
The robbed-bit call-control mechanism that the MAX unit uses for
inband signaling.
inband signaling.
Switch Type
Type of switch (carrier specific) providing the ISDN service.
Framing Mode
Physical-layer frame format of the T1 line.
Front End
Type of interface used on the T1/PRI port. Select CSU (the default) if
you plan to use the MAX unit’s internal CSU, or select DSX if you
plan to connect the port to other equipment that provides the interface
to the WAN, (an external CSU, for example), and disable the internal
CSU.

Encoding
Type of encoding that the line uses at the physical-link layer.
Length
The distance between the CSU and the MAX unit. Applies to a MAX
using external CSUs only.
using external CSUs only.
Buildout
Amount of attenuation, in decibels, to apply to the internal CSU.
Consider specifying a value if the MAX is using an internal CSU too
near a repeater. For additional information, consult your carrier.

Clock Source
That the line can (Yes) or cannot (No) be used as the clock source for
timing synchronous transmissions between the sending and the
receiving device. A MAX unit only has one clock source. The first line
that comes up is the clock source for all the lines. If you set this
parameter to No, the MAX uses its internal clock.

Collect DNIS/ANI
That DNIS and CLID information from the switch are (Yes) or are not
(No) available for authentication and accounting. Applies to inband
signaling only. With the Yes setting, the Digital Signal Processor
(DSP) decodes the calling and called DTMF digits.

presented, before clearing the call.
