5.4 POWER CONNECTION
Universal AC Power (100-240VAC)
The Model 1088 uses a 5VDC, 2A universal input 100-240VAC,
power supply (center pin is +5V). The universal input power supply
has a male IEC-320 power entry connector. This power supply con-
nects to the Model 1088 by means of a barrel jack on the rear panel.
Many international power cords are available for the universal power
supply. Please refer to Appendix B for country-specific power cords.
The Model 1088 powers up as soon as it is plugged into an AC
outlet. The Model 1088 does not have a power switch.
120 VAC Power (US)
The 100-132 VAC adapter supplied with the U.S. version of the
Model 1088 is a wall mount type and may be plugged into any
approved 120 VAC wall jack.
230 VAC Power (International)
The 230 VAC adapter supplied with the International version of the
Model 1088 is a wall mount type and may be plugged into any
approved 230 VAC wall jack.
DC Power
The 36-60 VDC DC to DC adapter is supplied with the DC version
of the Model 1088. The black and red leads plug into a DC source
(nominal 48VDC) and the barrel power connector plugs into the barrel
power supply jack on the rear panel of the 1088. (See Figure 8).

When the Model 1088 has been properly configured and installed,
it should operate transparently. This sections describes power-up,
LED status monitors, and the built-in loopback test modes.
6.1 POWER-UP
Before applying power to the Model 1088, please read
Section
5.4 and ensure
that the unit is connected to the appropriate power
source.
6.2 LED STATUS MONITORS
The Model 1088 features six front panel LEDs that monitor con-
nections on the DSL and 10BaseT links, signaling, error and test
modes. Figure 9 (below) shows the front panel location of each LED.
Descriptions of each LED follow Figure 9.
DSL Link
(Active Green) Solid green (On) indicates that the
end to end DSL Framer Link is up, signifying that
the link across the DSL span is active. The DSL
Link LED is Off when the link is down.
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
16
