SDM-309B Satellite Modem
Operation
MN/U-SDM309B Rev. #
3–9
CODING
Programs the modem for “AMI”, “B8ZS”, “B6ZS”, or “HDB3” coding of the
baseband data.
On entry the current coding format is displayed. Use the arrow keys to
select the desired coding format. Press the “ENTER” key to execute the
change.
TX_2047
*Programs the modem to insert a 2047 pattern in lieu of the normal transmit
data.
On entry the current status is displayed with the flashing cursor on the first
character. Use the arrow keys to select ON or OFF. Press the “ENTER” key
to execute the change.
TXD_FLT
Transmit Data Fault. This configuration function is used to select a Transmit
Interface fault monitor of AIS, Data, or None. When AIS (Alarm Indication
Signal) is selected the TX_INTF (Transmit Interface) fault “Data/AIS” is
monitoring a fault condition of all 1’s from customer data input to the
modem. When Data_Flt is selected, the TX_INTF fault “Data/AIS” is
monitoring a fault condition of all 1’s or all 0’s. This is referred to as a data
stable condition which means that the data is not transitioning. When None
is selected, the TX_INTF fault “Data/AIS” is not activated. On entry the
current TX Data fault that is being monitored is displayed with the flashing
cursor on the first character.
Use the arrow keys to select Data, AIS, or None. Press the “ENTER” key to
execute the change.
RXD_FLT
Receive Data Fault. This configuration function is used to select a Receive
Interface fault monitor of AIS, Data, or None. The data monitored for
Receive Data is coming from the Satellite. Refer to TXD_FLT for a
description of the function choices.
On entry the current RX Data fault that is being monitored is displayed with
the flashing cursor on the first character. Use the arrow keys to select Data,
AIS, or None. Press the “ENTER” key to execute the change.
BUF_SIZE
This configuration function is used to set the size of the plesiochronous
buffer.
On entry the current plesiochronous buffer length is displayed. Use the up
and down arrow keys to select the desired buffer size. You may select from
384 to 262,144 bits in increments of sixteen. Press the “ENTER” key to
execute the change.
BUF_CNTR
This configuration function is used to center the plesiochronous buffer.
Press the “ENTER” key twice to center the plesiochronous buffer.
READ_ERR
This configuration is used to select the read error function mode. Frame or
2047 errors may be selected.
On entry the current read error mode is displayed. Use the arrow keys to
select “2047” errors or “FRAME” errors as desired. Press the “ENTER” key
to display and monitor the selected errors. To exit the read error mode press
the “CLEAR” key.
Dscrmblr
Programs the demod/decoder for descrambler On or Off.
On entry the current status of the descrambler is displayed with the flashing
cursor on the first character. Use the arrow keys to select ON or OFF. Press
the “ENTER” key to execute the change.
Scramblr
Programs the modulator for scrambler On or Off.
On entry the current status of the scrambler is displayed with the flashing
cursor on the first character. Use the arrow keys to select ON or OFF. Press
the “ENTER” key to execute the change.
* Indicates Test Mode configuration option.
