Creating an IP port range
After you have properly allocated all of your system's phy
sical interfaces, you must create a new IP port range.

Table 3. Configuration Parameters for New Line Services
Parameter Description
Name Used by the Web Portal to indicate a specific object or string in the system
Local Index Assigns an integer to represent an object
Framing Sets a framing type for a line service. Select from:
AUTO (typical for E1)/STD/MFRAME/SF/ESF (typical for T1)/SLC96
Loopback
Used to set a loopback state for a line service. Refer to
Table 4
for details.
Table 4. Loopback Types
Loopback Type Description Behavior Use
NONE Normal
Operation
All traffic is received and sent on the line Always
LINE Analog Line
Loopback
All received traffic is re-routed on the transmit
line. The clock and data recovered from the
line inputs are routed back to the line outputs
of the analog transceiver bypassing the framer
modules.
First step in testing a
physical connection
PAYLOAD Digital Line
Loopback
All received traffic is re-routed on the transmit
line.The clock and data recovered from the
line inputs are routed back to the line outputs
after the deframer/framer.
Second step in testing a
physical connection.
This tests the framer
configuration.
GENERATE_LOS Generate Loss
of Signal
This forces the transmit line to stop sending. This is the second-best
thing to disconnecting
the line interface physi-
cally.
LOCAL Local Loopback All received traffic is dropped. The traffic sent
is re-routed internally.
Never. Used for inter-
nal testing only
