1. GENERAL
The ADTRAN E220 HDSL / HDSL2 Fuse/Alarm/
Control (HFAC), P/N 61221051L1, unit is a shelf
controller unit designed for operation in the ADTRAN
E220 HDSL / HDSL2 Central Office (CO) shelf.
Figure 1 is an illustration of the E220 HFAC.
Revision History
Revisions to this practice will be summarized in this
paragraph.
The E220 HFAC provides a common access point to
performance and provisioning information related to
each HDSL / HDSL2 transceiver unit for the central
office (HTU-C and H2TU-C) deployed in the E220
shelf. By addressing the HTU-C or H2TU-C, the HFAC
also provides support for the HDSL / HDSL2 range
extender (HRE and H2R) and the HDSL / HDSL2
transceiver unit for the remote end (HTU-R and H2TU-R).
The shelf supports one shelf controller (HFAC) and up
to 13 HTU-C / H2TU-C cards for the 23-inch shelf or 11
HTU-C / H2TU-C cards for the 19-inch shelf. A
faceplate-mounted DB9 connector provides a VT 100
compatible terminal interface for controlling the
system.

The locations shown in Figure 4 are monitored for
Severely Errored Seconds and counts are maintained
for each location. If any of these counts exceed the
SES programmed threshold (see Tables 1 and 2) an
alarm will be generated. This alarm threshold and the
alarm type (minor or major) can be programmed by
setting switches S1 and S2 (Figure 2) to the
appropriate positions according to Tables 1 and 2.
The alarm thresholds are for the 15-minute registers
only, and the 15-minute SES counts are zeroed at each
15-minute boundary. The SES alarm threshold and
alarm type can also be configured in the Craft
interface Options Setup screen (see Figure 11).
registers only, and the 15-minute UAS errored second
counts are zeroed at each 15-minute boundary. The
UAS alarm threshold and alarm type can also be
configured in the Craft interface Options Setup screen
(see Figure 11). Note that HDSL2 two wire units only
have Loop 1.
HFAC Alarm Outputs
If an HFAC is present in the shelf, alarm outputs are
available on the backplane wirewrap pins
corresponding to the HFAC slot (see Figure 5).
These outputs are dry contact relay connections and
provide normally open, normally closed and common
connection points for alarm monitoring equipment.
Alarm connection points corresponding to critical
major, and minor alarms (both visible and audible) are
provided. These alarms are generated by the HFAC as
a result of processed data collected from the HTU-Cs /
H2TU-Cs.
Unavailable Seconds (UAS) Alarm
The locations shown in Figure 4 are monitored for
unavailable seconds. Seconds and counts are
maintained for each location. If any of these counts
exceed the UAS programmed threshold (see Tables 1
and 2), an alarm will be generated. This alarm
threshold and the alarm type (major or critical) can be
programmed by setting switches S1 or S2 (Figure 2)
to the appropriate positions according to Tables 1 and
2. The alarm thresholds are for the 15-minute
Alarm outputs presented on these pins are
programmable and can be provisioned in the HFAC
Options Setup screen (see Options Setup screen), or
using the HFAC dip switch settings (see Tables 1, 2,
and 3). Alarm severity can be provisioned for alarms

resulting from blown fuses in the HFAC, HTU-C, or
HCOT units, or from communications failure between
any HTU-C and the HFAC. Alarm severity and
threshold value can be provisioned for the errored
second, severely errored second, and unavailable
second parameters.
System Communications
An option available on the HFAC Option Setup screen
allows external DSX-1 or DS1 alarms to be enabled or
disabled. This option can only be changed in the
HFAC menu (no dip switch option) and the factory
default is disabled (see Table 5).
If the HFAC is to be used as part of a larger system
under the control of an ADTRAN E220 HCOT-CTL
system controller, then shelf-to-shelf connections are
required. Two RJ45S jacks, JP6 and JP7, located on
the shelf backplane, provide shelf-to-shelf
communications. A 4- or 8-wire cable with RJ45S
type jacks should be used to supply these
interconnections. The sequence of connections should
be from the RS422 OUT port of the shelf containing
the E220 HCOT-CTL system controller to the RS422
IN port of the next shelf. Follow this procedure to
HFAC Fuse Alarm
An alarm may be generated as a result of an HFAC
fuse failure. For alarm processing to work, two sets of
switches (S1 and S3) must be programmed. See Table
1 and 4. Both switches must be set properly for the
HFAC fuse alarm to operate correctly.

Figures 10 and 10A consolidate current information for
the HDSL / HDSL2, DSX-1, and DS1 interfaces. A key
to the information provided is found in the center of the
screen. Arrows indicate the key applies to both the
HTU-C and HTU-R.

the screen. The measure is from 0 (poor signal quality)
to 9 (excellent signal quality). Guidelines for interpreting
the indicators are given below.

Margin measurement above 10-7 BER in dB
Margin is ≥ 9 dB above 10-7 BER
and the second is the current 24-hour period (Loop 1 and
Loop 2 numbers are displayed).
An indication of Pair Reversal (if present) is given at the
bottom of the first key column. Loopback status for the
HTU-C, HRE, and HTU-R is indicated on these screens.
Status and configuration information for the DS1 and
DSX-1 signals is located in the center of the screen near
the bottom.
Predicting performance based upon signal quality varies
with each loop. Generally, a noise margin of 0 or higher
will support a bit error rate of better than 10-7.

Provisioning Summary Screen
due to faults at any of the HDSL / HDSL2 loop, DSX-
1, or DS1 locations. The Disable All disables all
alarms due to external faults or faults within the
HDSL / HDSL2 equipment or loops.
Selection of item 8 from the Main Menu supplies
provisioning information on individual circuits being
accessed by the HFAC. Figure 20 is a slot-specific
provisioning screen showing the provision option
item, current settings, and hardware settings for that
particular circuit. A key at the bottom of the screen
describes the options associated with this screen.
The Disable EXT selection allows only alarms caused
by faults in the HDSL / HDSL2 equipment or HDSL /
HDSL2 loops and suppresses alarms caused by
external DSX-1 or DS1 faults.
Menu item 7 provides a means of provisioning
specific HTU-C units, from the HFAC, to enable or
disable various HTU-C alarms. This option is
different from the Disable Alarms option on the
HFAC Options Setup screen. This option sets the
selected HTU-C to enable or disable the alarms
presented on the HTU-C edge connector pins 20 and
21 (closure between pins) and edge connector pin 1
(closure to ground).
NOTE
ADTRAN 220/E220 H2TU-Cs support an
EXTERNAL LBO option for use in legacy
220 ORB shelves. The ADTRAN E220 shelf
doesnotrequiretheEXTERNALLBOoption.
The E220 HFAC will not allow the selection
of the EXTERNAL LBO setting when
initiated through the HFAC terminal screen.
It should be noted that the HFAC will not
automaticallyoverrideanEXTERNALLBO
setting.
The Enable All selection permits alarms to be
presented on the aforementioned edge connector pins
