T3 Network Interface
FrameSaver Models 9520 and 9520-ILM have a T3 network interface.
Table 3-8. T3 Network Physical Interface Options
Circuit Identifier
Possible Settings: ASCII Text Entry, Clear
Default Setting: blank
Identifies the transmission vendor’s circuit information to facilitate troubleshooting.
ASCII Text Entry – Edit or display circuit identifier information (maximum 255 characters).
Clear – Removes the circuit identifier information.
Line Build Out
Possible Settings: Short, Long
Default Setting: Short
Specifies the line build out for the signal transmitted to the network.
Short – Activates an equalization filter to simulate a longer cable. Use this option for a
network cable less than 100 feet.
Long – The equalization filter is bypassed. Use this option for a network cable 100 feet or
longer.
Network Initiated LLB
Possible Settings: Enable, Disable
Default Setting: Enable
Allows the initiation and termination of the line loopback (LLB) to be controlled by the
receipt of LLB-Actuate and LLB-Release commands from the network.
Enable – LLB is controlled by LLB-Actuate and LLB-Release commands. Receiving a
LLB-Actuate command causes the FrameSaver unit to enter a line loopback (provided an
LLB can be performed in the FrameSaver unit’s current state). Receiving an LLB-Release
command terminates the LLB.
Disable – The FrameSaver unit ignores the LLB-Actuate and LLB-Release commands.
