LEDs and DIP Switches C-3
Modem Indicators
Each V.34 or I-modem indicator (1 - 16) shows the status of one
modem. The number for each modem corresponds to its port
number (mod:1, mod:2, etc.). These LEDs display the following:
Color Meaning
Off
Idle, ready to make/receive calls
Green (solid)
On-line
Green (flashing)
Testing datalink layer
Amber (rapid flash)
Seeking U interface (I-modem)
Amber (slow flash)
Seeking S/T interface (I-modem)
Amber (solid)
Dialing
Red (solid)
U interface not found
Red (flashing)
Critical failure or wrong SPID (I-modem)
Whenever a modem is reset, these LEDs cycle briefly through all
three colors. This happens when the power is first turned on
(all modem LEDs cycle in unison) and when one of the modems
is reset by software. Note that when the NETServer finishes its
POST test, it initializes the modems one by one, causing the
LEDs to cascade through all three colors.
