OM20 Universal Outdoor Modem Web Browser/Remote Protocol
MN-OM20– Revision 5 6–38
SCT Clock Source: {SCT, SCR}
Allows the user to select SCT Source. SCT is the internally
generated SCT clock. SCR is the Rx Satellite clock. SCR us used
for loop timing.
SCT Clock Polarity: {AUTO, NORMAL, INVERTED}
Allows the user to select the Clock Polarity for the SCT Clock
relative to the Tx Data. “Auto” detects wrong polarity and
automatically corrects. If G.703 Interface is selected, this
selection cannot be changed.
Esc Ch. 1 Gain Provides gain in channel 1of engineering service channel in 96K
framing mode.
Esc Ch. 2 Gain Provides gain in channel 2 of engineering service channel in 96K
framing mode.
Eth Flow Control: {Disabled, Enabled}
Allows the user to disable or enable flow control. Only visible
when Ethernet is selected as the interface type.
Eth Daisy Chain: {Disabled, Port 4}
Allows the user to disable the Ethernet Port Daisy Chaining or
enable it on Port 4. Only visible when Ethernet is selected as the
interface type.
ETH QOS Type {NORMAL, PORT BASED}
Selects the standard DMD20 priority hierarchy of processing an
IEEE 803.3ac Tag, Ipv4 Type of Service Field / Differentiated
Services Field, or Ipv6 Traffic Class Field. The Port Based
priority overrides any standard priority. When operating in this
mode, Port 1 (JS1) has the highest priority and Port 4 (JS4) has
the lowest.
ETH QOS Queue {FAIR WEIGHTED, STRICT PRIORITY}
Selects the standard DMD20 queue weighting of 8,4,2,1 that
insures even the lowest priority traffic gets some bandwidth.
Strict Priority insures that the higher priority traffic will always
be transmitted before any lower priority traffic. With this setting,
the lower priority traffic can starve.
TX ASYNC
Async Mode: {ES-ES, ESC ENHANCED}
ES-ES is the normal IBS Async Channel. ESC Enhanced can be
selected in Closed Net and uses the Overhead Signaling bytes in
the IBS Overhead to pass asynchronous data. This menu is not
available when SCC is selected.
ES Interface: {RS-232, RS-485}
Allows the user to select the interface type.
