DMD20/DMD20 LBST Universal Satellite Modem
Allows the user to disable or enable flow control. Only
visible when Ethernet is selected as the interface
type.
{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.
{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.
{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.
{SCTE, SCT, EXT CLK}
Allows the user to select the Transmit Clock Source.
{AUTO, NORMAL, INVERTED}
Allows the user to select the Clock Polarity for the Tx
Terrestrial Clock relative to the Tx Data. "Auto" detects
wrong polarity and automatically corrects. If G.703
Interface is selected, this selection cannot be changed.
{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.

{NONE, T1-D4, T1-ESF, PCM-30, PCM-30C, PCM-31,
PCM-31C, T1-D4-S, T1-ESF-S.}
Drop mode may only be changed from none when the
drop and insert specified is in use.
{SRC Map Dest Map}
Allows the user to copy drop and insert maps. Tx Act
map is the drop map currentlt being used by the modem.
Source and destination may be any of the following:
TX ACT, RX ACT, TX EDIT, RX EDIT,
USER 1 - USER 8, ROM 1 -ROM 8
