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.

61221051L1-5A Trademarks: Any brand61221051L1names and product-5,namesIssueincluded1in this document are 1 trademarks, registered trademarks, or trade names of their respective holders.

The HFAC supports the HTU-Cs / H2TU-Cs listed below.

1242024L1

• 1242002L7

1242002L2

• 1242029L1

• 1245001L2

• 1246001L2

• 1245001L9

• 1221001L2

• 1245011L1

 

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 also allows control of all provisioning information for each circuit. The unit can also be configured to provide advanced alarm processing features.

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 ADTRAN E220 HCOT-CTL System Controller, each individual shelf must be programmed with a unique shelf address. Addresses range from 00 to 99. In a system that does not utilize the HCOT-CTL System Controller, the shelf address is not used. To program

the address, select the desired address in the Options Setup Screen (Figure 11), or set the rotary switches as indicated in Figure 2.

Unit Options

Two banks of configuration switches (S1, S2 and S3, see Figure 2 and 3) are used to select advanced alarm reporting features (see Tables 2, 3 and 4).

Errored Seconds (ES) Alarm

The locations shown in Figure 4 are monitored for errored seconds and counts are maintained for each location.

If any of these counts exceed the ES 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 ES counts are zeroed at each 15-minute boundary. The ES alarm threshold and alarm type can also be configured in the Craft interface Options Setup screen.

Figure 4. ES, SES, and UAS Monitor Locations

Severely Errored Seconds (SES) Alarm

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).

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

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.

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.

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).

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.

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 wire wrap connections to the backplane-mounted connector. JP1 is the primary interface connector for the HFAC. Figure 5 shows the wire-wrap connector terminal pin assignments.

Alarms

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 or normally closed connections for alarm conditions. 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 HFAC, or by providing closure between the Remote ACO pins on the JP1 connector. The backplane is labeled with appropriate markings for the alarm and alarm cutoff connections.

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

6

61221051L1-5A

interconnect subsequent shelves. Each shelf controller 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.

4. FACEPLATE FEATURES

Table 6 defines the faceplate features of the HFAC.

5. CONTROL PORT OPERATION

The HFAC provides a faceplate-mounted DB9 connector which supplies an RS232 interface for connecting to a controlling terminal. Pin assignments are shown in Figure 6.

Minor (yellow) ... Indicates that a minor alarm condition is present.

 

ACO ................. Alarm cut off. Indicates that the audible portion of an

 

alarm has been terminated.

 

 

SHELF

The shelf address is indicated using two 7-segment LED displays. The

ADDRESS

address is programmed using the switches described in subsection 2 and

 

tables A and B; or using the Options Setup screen (see Figure 11).

A terminal session is initiated by entering multiple space bar characters which are used by the HFAC to determine the speed of the terminal. Once the speed has been derived, an Introductory Menu is presented as illustrated in Figure 7. This screen includes ADTRAN

technical support phone numbers along with serial numbers, CLEI codes, date of manufacture information for each active HDSL / HDSL2 system element, and if the circuit has an installed HDSL / HDSL2 range extender (HRE / H2R).

NOTE

The command keys valid for each screen are shown at the bottom of the display. Pressing keys other than these may cause the HFAC to adjust to a different speed. If this happens, the HFAC will not respond to keyboard commands and may display random characters. Press the space bar repeatedly until the screen is re-displayed.

A measure of signal quality for each HDSL / HDSL2 loop is displayed in graphic form on the bottom right of the screen. The measure is from 0 (poor signal quality) to 9 (excellent signal quality). Guidelines for interpreting the indicators are given below.

0Noise margin is £ 0 dB (» 10-7 BER)

1-8

Margin measurement above 10-7 BER in dB

9Margin is ³ 9 dB above 10-7 BER

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.

ADTRAN has defined the following as guidelines that correspond to the operation of the HTU-C and HTU-R faceplate LEDs labeled LP1 and LP2.

Margin < 0 Poor Loop Signal Quality

0 £ Margin £ 2 Marginal Loop Signal Quality Margin > 2 Good Loop Signal Quality

(better than 10-9 BER)

Alarm Status Screen

Selection of item 3 from the Main Menu presents the Alarm Status Screen, Figure 14. This screen is a composite display of all current alarms for each of the 13 slots. Alarm types are indicated by the number 1 for Critical, 2 for Major, and 3 for Minor alarms.

A capital A indicates the alarm is current while a trailing * indicates the alarm cutoff has been exercised. ES or SES indicates the programmed threshold has been exceeded, resulting in an alarm. The position of the alarm indicator codes in the screen matrix indicates

both the alarm location and slot number.

Alarm History Screen

The Alarm History Summary Screen (Figure 15) can be accessed from the Alarm Status Screen by pressing H. This screen provides a time and date stamp for up to 100 alarm events. These events include alarm initiation and alarm clear. For convenience, a user marker can be invoked by pressing X. This produces a highly visible marking point so that subsequent alarm events can be easily distinguished from older ones.

Loopback Status Summary Screen

Item selection 4, Loopback Control, from the Main Menu displays the loopback status information for all of the HTU-C, HRE, and HTU-R units monitored by the HFAC. Loopback Status (On, Off, or Not available) is presented for loopbacks to both the network and the customer at both the HTU-C, HRE, and HTU-R. Figure 16 illustrates the Loopback Status Summary Screen.

Loopback Options

By pressing a slot number followed by an S from the

Loopback Status Summary Screen, you will be presented with a slot-specific Loopback Options Screen (Figure 17). Multiple loopbacks can be initiated for each circuit. This screen graphically depicts the loopback activated by showing through reverse video, the path of the loopback and the locations it loops to. Also, the status indication changes from inactive to active. The initiation of a loopback is accomplished by pressing the corresponding number of the loopback desired, followed by an L.

Troubleshooting Screen

The Troubleshooting Screen (Main Menu, Item 6) provides a graphical presentation of trouble areas. Different parts of the diagram will be highlighted (on terminals that support reverse video) to indicate the trouble locations. In addition, in-band alarms and indicated problem areas are presented in text under the troubleshooting diagram. Use of this screen in conjunction with performance data and alarm status screens provides a reliable method of quickly locating system faults. Figure 18 shows the Troubleshooting Display.

Provisioning Summary Screen

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.

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).

The Enable All selection permits alarms to be presented on the aforementioned edge connector pins

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.

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.

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 automatically override an EXTERNAL LBO setting.
