User InterfacesDMD15/DMD15L IBS/IDR Satellite Modem

Tx D&I (menu):

 

Drop Mode:

{Enable, Disable}

 

Allows the user to enable or disable the following:

 

T1-D4, T1-ESF, PCM-30, PCM-30C, PCM-31,

 

PCM-31C, SLC-96, T1-D4-S, T1-ESF-S.

Map Copy:

{Rx Edit, Tx Edit, Rx Acti, Tx Acti, ROM 1…ROM 8,

 

User 1…User 8}

 

Allows user to copy Drop and Insert maps. If the user

 

attempts an invalid copy, the error prompt “BAD

 

DESTINATION” will be displayed and the copy will not be

 

allowed. The Tx Active map is the drop map currently

 

being used by the modem. For a more detailed

 

description of this function, see Section 4.6.4.

SATCh TS:

Allows the user to edit the Tx Edit Map to specify the

 

terrestrial slots that will be dropped into which satellite

 

channels. The Satellite Channels are fixed and the

 

number of channels are determined by the data rate.

 

The Terrestrial Timeslots available are determined by the

 

Drop Mode. When the user has finished editing the Tx

 

Edit map, it must be copied to the Tx Active map before

 

it can be used by the modem.

Time Mark:

{Enable, Disable}

 

Allows the user to enable or disable the “Time Mark

 

Transfer” (TMT) Transmit Request External Input to

 

initialize the state machine that detects the proper states

 

of I and Q and inserts the TMT Pattern into the transmit

 

symbol stream. This feature is only available in BPSK,

 

QPSK, and OQPSK Modulations and requires specific

 

hardware and configuration at the factory.

TMT Length:

{4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16}

 

Allows the user to set the length of the pattern marker.

 

This feature is only available in BPSK, QPSK, and

 

OQPSK Modulations and requires specific hardware and

 

configuration at the factory.

Rx Setup (menu):

 

Rx Ckt ID:

Provides entry of Rx Circuit Identifier. Circuits can be

 

given up to an 11 Character alphanumeric Identity such

 

as DLINK1

Rx Type:

{G.703 (Balanced/Unbalanced), V.35, RS-232, RS-

 

422}

 

Allows the user to select the Receive Type.

Buff Size:

{0-32 msecs}

 

Allows the user to set the Doppler Buffer Size in msec.

Buff Clk:

{SCTE (External), SCT (Internal), Rx Sat, EXTCLK}
