BUFFER CLOCK CONTROL
Buffer Size (msec):
{0 - 64 msecs}
Allows the user to set the Doppler Buffer Size in msec.
Buffer Clock Polarity:
{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.
Number of Buffer Sources:
{1 – 5}
Allows the user to select up to 5 clock sources.
Active Buffer Clock:
{RXSAT, EXTBNC, SCTE, SCT, EXT IDI}
Shows the current active buffer clock source.
BUFFER CLOCK SOURCES
Source 1 of 1:
{SCTE, SCE, RX SAT, EXT BNC, EXT IDI}
Source 2:
{SCTE, SCE, RX SAT, EXT BNC, EXT IDI}
Source 3:
{SCTE, SCE, RX SAT, EXT BNC, EXT IDI}
Source 4:
{SCTE, SCE, RX SAT, EXT BNC, EXT IDI}

RX ASYNC
Async Mode:
{ES-ES, ESC ENHANCED}
ES-ES is displayed when IBS Network Spec is selected. ESC

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.
ES Baud Rate:
{150 – 1024} For IBS ES to ES
{150 – 19200} For ES to ES Enhanced
{150 – 115200} For SCC Communications
ES to ES : Fixed Baud Rate based on IBS Network
Specification. Available rates are listed in Table 3-3.
