PERATION
Port Rate
Selects the required port bit rate in increments of 56 or 64 kbps, depending on the
selection in Rate Multiplier. The N multiplier ranges in value from 0 to 24.
# of Channels
Displays the number of channels to be passed through to Port 1. This number is
determined by the selection in Port Rate.
Transmit Clock
This field selects whether the INTERNAL DTE port clock or the EXTERNAL
terminal clock is used when data is transmitted from the DTE.
V.54 Loop
Selecting Enable allows the unit to respond to in-band V.54 loop commands. If
Disable is selected, the unit ignores these commands.
Invert Data
In the invert mode (YES), transmit and receive data are inverted at the port
interface. This function may be used as a means of guaranteeing ones density
when the data is composed of SDLC-type protocols. The choices are YES and NO.
CTS,DSR, and DCD Control
Setting any of these three fields to FORCE TRUE or FORCE FALSE allows the
forcing of the port control lead output state. INTERNAL allows for normal
operation as shown in Figure 4-12.
