User Interfaces DMD2050 Universal Satellite Modem
4-18 TM110 - Rev. 1.3
BUFFER CLOCK POL {NORMAL, INVERTED}
Allows the user to select the Buffer Clock Polarity for the
Tx Terrestrial Clock relative to the Tx Data. If G.703
Interface is selected, this selection cannot be changed.
DROP & INSERT (menu)
INSERT MODE {NONE, T1-D4, T1-ESF, PCM-30, PCM-30C, PCM-31,
PCM-31C, T1-D4-S, T1-ESF-S.}
Allows the user to select any of the above.
T1/E1 FRAME SRC {INTERNAL, EXTERNAL, IDI/DDO LOOPBACK}
Selects the frame source for T1 or E1 framing.
Note: IDI/DDO loop is an internal loopback of the
terrestrial clocks not to be used simultaneously with
external loopback cable.
MAP COPY {TxACT, RxACT, TxEDIT, RxEDIT, USER1….USER8,
ROM1….ROM8}
Allows the user to copy drop and insert maps. RxACT
map is the insert map currently being used by the
modem.
SAT CH TERRCH Allows the user to edit the Tx edit map to specify the
terrestrial slots that will be dropped into assigned
satellite channels. The satellite channels are fixed ane
the number of channels are determined by the data rate.
The terrestrial time slots available are determinedddddd
by the drop mode. When the user has finished editing
the Tx edit map, it will be copied to the Tx ACT map
before it can be used by the modem.
TERR STREAMING {BYTE OUTPUT, PACKET OUTPUT} ASI only
Byte Output = Continuous Mode
Packet Output = Burst Mode
GENERAL (menu)
EXT FREQ (MHz) {Variable Through Data Rate}
Allows the user to select the external clock frequency in
MHz.
REF FREQ SRC {EXTERNAL, HIGH STABILITY}
Allows the user to select the Frequency Reference
Source.
REF FREQ (MHz) Allows the user to select the reference clock frequency
in MHz.
TX ASYNC MODE (menu)
TX ASYNC MODE {ES-ES, ESC ENHANCED}
ES-ES is the normal IBS Async Channel. ESC
Enhanced ca be selected in Closed Net and uses the
