MODMIM TROUBLESHOOTING

The MODMIM uses the same indicators as the CSMIM2-16 for its 16
asynchronous ports with the addition of 5 LEDS and a reset switch per
modem port. In normal operation, the port status indicators are as follows:

NOTE

The tftp dump names are user–defined. If a name is not
specified, the CSMIM2 uses the bfs convention.

Table 4-10

MODMIM Port Status Indicators

CTS

Clear to Send. ON until the modem lowers CTS when Transmission Data
hardware flow control is enabled (&H1, &H3). Always on during
synchronous connections.

DTR

Data Terminal Ready. ON when the MODMIM receives a DTR signal
from the computer or terminal.

TXD

Send Data. Flashes when the computer or terminal sends a data bit to
the MODMIM.

RXD

Received Data. Flashes when the MODMIM sends result codes or
passes received data bits to the computer or terminal.

DCD

Carrier Detect. On when the MODMIM receives a valid data signal
(carrier) from a remote modem, indicating that data transmission is
possible.
