Chapter 5: Configuration
5 sec or EON (default)
The ISU 512 assumes the dial string is fully entered if more than 5 seconds
elapse since input of the last digit, or an EON command is received. This is the
factory default setting.
10 sec or EON
The ISU 512 assumes the dial string is fully entered if more than 10 seconds
elapse since input of the last digit, or the unit receives the EON command.
20 sec or EON
The ISU 512 assumes the dial string is fully entered if more than 20 seconds
elapse since input of the last digit, or the unit receives the EON command.
Wait for EON
The ISU 512 assumes the dial string is fully entered only if the unit receives the
EON command.
See the section RS-366 Y Cable in this chapter for information on enabling the RS-
366 Y cable for dual-port video applications.

This option should remain disabled for all normal commercial applications. It
is designed for use with only a few specialized military applications and is not
described in this manual. For more information on this option, contact ADT-
RAN Technical Support (see the inside back cover).
V.25 bis
Configuring the ISU 512 for HDLC V.25 bis enables in-band dialing over a
DTE interface using standard synchronous HDLC V.25 bis commands with
Mark Idle. Configuring the ISU 512 for HDLC(FLAGS) V.25 bis enables in-
band dialing over a DTE interface using standard synchronous HDLC V.25 bis
commands with 7E HEX idle. V.25 bis can be used to establish and end a call.
Calls can be disconnected using the front panel, a VT 100 terminal, or from the
far-end unit. See Configuring the ISU 512 for V.25 bis In-band Dialing in this
chapter for more information.
