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.
Copy drop and insert maps. RxACT map is the insert map currently
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
Edit the Tx edit map to specify the terrestrial slots that will be dropped
into assigned satellite channels. The satellite channels are fixed and
the number of channels is determined by the data rate. The terrestrial
time slots available are determined by the drop mode. The finished Tx
edit map is copied to the Tx ACT map before it is used by the modem.
ES-ES is displayed when IBS Network Spec is selected. ESC
Enhanced can be selected in Closed Net and uses the Overhead
Signaling bytes in the IBS Overhead to pass asynchronous data. This
menu is not available when SCC is selected.
Select the interface type.
ES to ES: Fixed Baud Rate based on IBS Network Specification.
