2.3 TYPICAL APPLICATION

The Model IM1/I QuickConnect™ is designed to plug directly into

the rear of a Patton Electronics baseband modem (i.e. Model 1090 or
1092). The Model IM1/I is designed to be used as one of a pair of
units. Figure 1 (below) illustrates a typical Model IM1/I installation.

6.3 LED STATUS MONITORS

The Model IM1/I features two LEDs that monitor general operating

status and the 10Base-T twisted pair link integrity. Figure 6 (below)
shows the LEDs located directly beneath the RJ-45 jack. Following
Figure 6 is a description of each LEDs function.

Status

Blinks yellow from one to eleven times to indicate
system status. Each pulse pattern is separated by a
2 second “off” period. Greater pulse patterns have
higher priority (buffer saturation has greater priority
than an empty MAC table). Valid system statuses
are:

1 pulse = system status is okay
2 pulses = no MAC entries in the MAC Address Table
3 pulses = Clear to Send (CTS) or Carrier Detect

(DCD) from base unit are not asserted

4 pulses = IM1/I buffer is saturated
5 pulses = WAN receive frame(s) too large
6 pulses = WAN receive frame(s) not octet aligned
7 pulses = WAN receive frame(s) aborted
8 pulses = Detected WAN receive frame(s) with CRC
9 pulses = Detected LAN receive frame(s) too large
10 pulses = Detected LAN receive frame(s) not octet

aligned

11 pulses = Detected LAN receive frame(s) with bad

CRC

Link

Glows green to indicate good link integrity on the
10Base-T twisted pair line.
