ASCII-Based Terminal 6
In Release 5 and later releases, an ASCII-based terminal may be used to
interface with the FT-2000 OC-48 Add/Drop-Rings Terminal. Users communicate
with the FT-2000 OC-48 Add/Drop-Rings Terminal using an ASCII-based terminal
and TL1 messages. The same TL1 message set is used by the message-based
operations system interface (X.25/TL1). The TL1 messages must be entered
manually by an experienced user.
In Release 5 and later releases, the TL1 message set consists of maintenance
commands (excludes autonomous messages) and cannot be used to install
software in an FT-2000 OC-48 Add/Drop-Rings Terminal. On-line help messages
and menus are not supported. For detailed information about TL1 messages,
refer to 824-102-151,

.
An ASCII-based terminal must meet the following minimum requirements to be
used as a CIT:
n ASCII-based data communications terminal with an 80-column display
n Scroll capability
n Local echo
n Serial port (EIA-232-D)
n Data transmission speed should be from 1200 to 9600 baud
n XON/XOFF flow control capability.
The ASCII-based terminal should be configured for byte serial data transmission
of 8-bit bytes with one start bit and one stop bit. Parity should be "none" and the
flow control should be "DC1/DC3." With flow control, entering <Ctl-S> stops the
output (X/off state), and <Ctl-Q><CR>, <Ctl-Q><Ctl-J>,or
<Ctl-Q><Ctl-M> resumes the output (X/on state).
