on page 33.

See the User’s Guide for additional information about:

 Configuration options  Messages and troubleshooting  Technical specifications  Cables, connectors, and pin assignments

Connecting Power to the Unit

If your package includes a power pack: Plug the power pack into an ac outlet having

a nominal voltage rating between 100–240 Vac. Connect the output cable of the power pack to the connector marked POWER on the rear panel.

If your package includes a direct-connection +24 Vdc power cable:

Connect the unit to an external +24 Vdc SELV (Safety Extra Low Voltage) power source as described in

Connecting the Unit to an Optional External +24 Vdc Power Source

If you will use a –48 Vdc power supply: Connect the unit to an external –48 Vdc SELV power source as described in the documentation shipped with the power supply and power cable.

Connecting the Unit to an Optional External +24 Vdc Power Source

Using the dc power cable, the Hotwire 79xx Standalone Termination Unit is capable of operating on a +24 Vdc SELV power supply.

 Procedure

To use the dc power cable:

1. Connect the green wire to a suitable ground.

2. Connect the orange wire to the +24 Vdc source.

3. Connect the white wire to the return.

4. Cut the black, red, and blue wires off at the outer insulation.

5. Plug the power connector into the 79xx Standalone Termination Unit.

Connecting to the Network

 Procedure

To connect your unit to the network:

1. Connect one end of the supplied network cable into the rear panel DSL jack.

2. Connect the other end to your DSL network interface.

NOTE:

not

use a flat VF network cable as this may severely degrade the

performance of the termination unit. Use only Cat 5 twisted-pair network cable.

Connecting to a DTE

Model DTE Connection

7974, 7984

The DSX-1 interface is an RJ48C, 8-position, unkeyed modular connector. An RJ48C-to-DB15 T1 network interface adapter cable is available from Paradyne.

7975, 7985

The synchronous interface is a 25-pin EIA-530-A interface. Depending on the cable used, the interface can be adapted to an X.21, RS-449, or V.35 interface.

7976, 7986

The G.703 interface is either two BNC connectors (Transmit and Receive) for a 75-ohm unbalanced interface or an RJ48C, 8-position, unkeyed modular connector for a 120-ohm balanced interface.

See

Cables and Pin Assignments

in the User’s Guide for specifications of the

connectors and cables.

Ferrite Choke (Model 7975 Only)

 Procedure

To install the ferrite choke onto the DTE cable:

1. Open the ferrite choke and place it around the cable as close to the cable connector as possible.

2. Close the two halves around the cable and snap the choke shut, pressing down on the plastic latch to secure it in place.

3. Add a tie wrap (not included) as shown to prevent the ferrite choke from slipping down the cable.

All ferrite chokes that are supplied must be installed following these instructions to ensure compliance with FCC Part 15, VCCI, and CISPR22 rules.

Connecting to a System Terminal

An optional system maintenance terminal may be attached to your Hotwire 79xx Standalone Termination Unit through the modular jack on the rear panel. The system maintenance terminal allows you to view the status of the unit and change configuration options. The terminal must be a VT100-compatible terminal or a PC running terminal emulation software.

 Procedure

To connect your unit to a system terminal:

1. Connect the 9-pin end of the terminal cable into a COM port on your PC.

2. Plug the other end into the modular jack on the rear panel.

3. Set the communication parameters on your PC or terminal to:

— 9600 baud — 8 bit characters — no parity — 1 stop bit — no flow control

Press Enter from your terminal or PC to activate the Main Menu for the attached unit. The system runs diagnostics and status checks. After a few moments, the Main Menu or Logon screen appears on your terminal.

Specifies whether the transmitted data for the synchronous data port is clocked using an internal clock provided by the LTU (synchronized to the clock source specified by the clock source configuration option) or an external clock provided by the DTE connected to the synchronous data port. If an external clock is used, it must be synchronized to the same clock source as the LTU.

Invert Transmit Clock

Possible Settings: Disable, Enable Default Setting: Disable

Specifies whether the clock supplied by the termination unit on the TXC interchange circuit DB (CCITT 114) is phase inverted with respect to the Transmitted Data interchange circuit BA (CCITT 103). This configuration option is useful when long cable lengths between the termination unit and the DTE are causing data errors.

Send All Ones on Data Port Not Ready

Possible Settings: Both, Disable, DTR, RTS Default Setting: Both

ElasticStore

Possible Settings: Disable, Enable Default Setting: Enable

Used to enable or disable a first-in, first-out (FIFO) buffer circuit for the incoming external clock. This circuit is used to compensate for the differences between the frequencies of the data clocks for the two units in the circuit. This option only applies if the unit is set for external timing. Do not enable Elastic Store if the attached DCE has an elastic store buffer larger than 32 bits.

Configuring the Unit Using the Internal Switches

Use internal Switchpacks S1 and S2 to manually configure the unit. Use the illustration on page 24 to locate Switchpacks S1 and S2.

HANDLING PRECAUTIONS FOR STATIC-SENSITIVE DEVICES

This product is designed to protect sensitive components from damage due to electrostatic discharge (ESD) during normal operation. When performing installation procedures, however, take proper static control precautions to prevent damage to equipment. If you are not sure of the proper static control precautions, contact your nearest sales or service representative.

 Procedure

To configure the unit using internal Switchpacks S1 and S2:

1. Power off the unit. Remove the enclosure cover by pushing a flat-blade screwdriver through the slots on both sides of the housing to free the four inner latches.

2. Locate Switchpack S1 on the circuit board.

3. Set Switch 1 on Switchpack S1 to ON to enable Switchpacks 1 and 2.

4. After you enable the switchpacks, you must set the switches to your desired

configuration. Refer to Tables 12 through 19.

5. Replace and secure the cover.

6. Power on the board to reset and enable the new configuration.
