Bit Rate
The Bit Rate can be set asynchronously for 300, 1200, 2400, 4800,
9600, 19200, 38400, 57600, and 115200 bps.
The Bit Rate can be set synchronously for 2400, 4800, 9600, 19200,
38400, 48000, 56000, 64000, 112000, and 128000 bps.
Connector Type
The ISU 2x64 can provide either an EIA-232, RS-530, or V.35 inter-
face to a user DTE by selecting the desired connector type. The
V.35 interface requires the RS-530/232-to-V.35 adapter, part num-
ber 1200072L1.
RTS Options
1 ms delay causes the Clear to Send signal to change state one
millisecond after the DTE Request to Send signal changes state.
The 18 ms delay causes the Clear to Send signal to change state
18 milliseconds after the DTE Request to Send signal changes
state.
CTS Options
Forced CTS causes the CTS signal on the DTE connector to be
continually asserted. Follows RTS causes the CTS signal to fol-
low the state of the RTS lead.
CD Options
CD Forced On causes the carrier detect (CD) signal to always be
asserted. Normal causes the CD signal to be asserted when a call
has been successfully established. Off with LOCD (local discon-
nect) causes the CD signal to be disasserted for a period of 5 sec-
onds and then be reasserted at the termination of a call.
Off Link
Down causes the CD signal to be disasserted when the ISDN
interface is not ready.
