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 HFAC supports the HTU-Cs / H2TU-Cs listed

The differences in functionality when working with
list-specific HTU-Cs / H2TU-Cs or HREs / H2Rs, if
any, are called out in this practice. Also, the HFAC
has necessary interface software for communications
with the HCOT-CTL (ADTRAN p/n: 1240009L1,
1244051L1, 1221051L1). See appropriate HCOT
practices for installation and maintenance information.
The HFAC collects and presents performance
information for each circuit deployed in the shelf. It

provide advanced alarm processing features.
2. INSTALLATION
CAUTION!
After unpacking the unit, inspect it for damage. If
damage is discovered, file a claim with the carrier,
then contact ADTRAN. See Warranty and Customer
Service.
Electrical cable compliance
Table 1 shows the Compliance Codes for HFAC. The
F1FAC complies with the requirements covered under
UL 1950 third edition and is intended to be installed
in an enclosure with an Installation Code (IC) of “B”
or “E.”
NOTE
This product is intended for installation in
Restricted Access Locations Only. Input
current at maximum load is 1A at -48 VDC.
Maximum output at overcurrent condition is
165 mA at -190 VDC.
Table 1. Compliance Codes
Code Input Output
Configuration
Operation of the HFAC is influenced by three sets of
configuration option switches (see Figures 2 and 3).
Shelf Address
Two rotary switches (U38 and U39) are provided to
program the shelf s address. In a system where
several shelves are under the common control of one

HFAC Alarm Outputs
If an FIFAC 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.
Alarm outputs presented on these pins are
programmable and can be provisioned in the FIFAC
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.

HTU-C Fuse Alarm
An alarm may be generated as a result of an HTU-C
fuse failure. The HFAC controller will sense the
failure and process this alarm event according to
switch settings as defined in Table 2.
3. CONNECTIONS
The HFAC plugs into Slot 0 (labeled HFAC) of the
ADTRAN E220 shelf. Push firmly to ensure the card
seats properly. Connections to the HFAC are made by
connector. JP1 is the primary interface connector for
the HFAC. Figure 5 shows the wire-wrap connector
A set of alarm contacts is provided through backplane
wire-wrap connections (Figure 5). Wiring can be
made to the appropriate pins on JP1 for normally open
Connection is made to the Common (C) pin and to the
Normally Open (NO) or Normally Closed (NC) pin.
Visible and audible alarm contact connections are
provided for critical, major, and minor alarms. An
audible alarm cutoff function can be initiated by
pressing the ACO push-button on the F1FAC, or by
providing closure between the Remote ACO pins on
the JP1 connector. The backplane is labeled with
An option available on the HFAC Option Setup sc
disabled. This option can only be changed in the
FIFAC menu (no dip switch option) and the factory
default is disabled (see Table 5).
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
FIFAC fuse alarm to operate correctly.
System Communications
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

should be assigned unique sequential shelf addresses.
No connection should be made to the RS422 in
connector on the shelf containing the E220 HCOT-CTL.
The terminal interface operates at a data rate range of
4.8 kbps to 19.2 kbps. The asynchronous data format
is fixed at eight data bits, no parity, one stop bit. The
supported terminal type is VT 100, or compatible.

Table 6 defines the faceplate features of the
HFAC.
