Installation and General Information

Installing an Interface Module


You can have up to two modules installed in your Signaling Advisor. However, the

number of modules can be extended by up to two if you have an undercradle fitted. The

modules operate in either slot. If only one module is fitted to your Signaling Advisor

then a Filler Panel must be fitted to the empty slot.

WAR NI NG If this product is not used as specified, the protection provided by the product

could be impaired. This product must be used in a normal condition only (in

which all means for protection are intact).

CAUTION To prevent possible system errors, you must turn off the power to the Signaling

Advisor before installing or removing a module.

To install a module (or Filler Panel) into a Signaling Advisor:

1 Ensure the Module Release Latch is in the unlocked position.

2 Fit and slide the module (or Filler Panel) into the opening on the side of the

instrument, see the following figure.

3 Push the module firmly into place until it is seated (the Module Release Latch

automatically moves to the locked position). If you are fitting a Filler Panel, you will

need to manually move the Module Release Latch to its locked position.

To remove an interface module (or Filler Panel) from a Signaling Advisor:

1 Depress the left end of the Module Release Latch (labeled PUSH TO UNLOCK)

then slide the latch to the left end (unlocked position).

2 Pull the module (or Filler Panel) out of the module.

To install an interface module into an undercradle:

1 Switch off the power to the instrument.

2 Fit and slide the module into the opening of the undercradle.

3 Push it into place until it is seated, see the figure below.

To remove an interface module from an undercradle:

1 Slide the Module Release Latch towards the left.

2 Pull the module out of the undercradle.

For more information, refer to the Installation Manual that is shipped with theundercradle.

Connecting Interface Modules to Bearers


Connections to the network are made with the two connectors on the interface module.

Each connector provides two V.35/RS-449/RS-232 full duplex links in Monitor mode.

In Emulate mode, the interface module can transmit V.35/RS-449/RS-232 signals.

CAUTION The ports on this module go low impedance when the Signaling Advisor is switched

off. If any port is connected to an unprotected monitor point, disconnect the cable

from the Signaling Advisor before powering off, otherwise the low impedance state

could adversely affect the network.

CAUTION When connecting or disconnecting, ensure that you are grounded or, make contact

with the metal surface of the mainframe with your free hand to bring you, the module,and the Signaling Advisor to the same static potential. Modules remain susceptible

to ESD damage while the module is installed in the Signaling Advisor. Additional

ESD precautions are required when servicing, see page 29.

NOTE The Bearer settings will be disabled when there is no adapter cable fitted, or when an

invalid or unsupported cable is fitted, or when the loopback connector is fitted.

Connecting to a V35, RS-449 or RS-232 Network Monitor Point

The module is automatically configured for a V.35, RS-449 or RS-232 network when

you switch on the Signaling Advisor and the appropriate V.35, RS-449 or RS-232

adapter cable is fitted to the module via the J4208A cable. The adapter cable currently

being used and the other module settings are displayed in the Signaling Advisors

Bearer view.

CAUTION The ports on this module go low impedance when the Signaling Advisor is switched

off. If any port is connected to an unprotected monitor point, disconnect the cablefrom the Signaling Advisor before powering off, otherwise the low impedance state

could adversely affect the network.

For more information on configuring the Signaling Advisors V.35/RS-449/RS-232

bearer settings in Monitor mode, refer to the instruments On-Line Help.

The following diagram shows how you make a bridged connection on a duplex link

when a monitor point is available.

The maximum combined length for the link plus drop cable is 15 m (RS-232), 1200 m

(RS-449) and 100 m (V.35).

7/30/2019 dcomref

14/36

Connecting for End Emulation

In Emulate mode, you can send and receive messages to/from another piece of

Network Equipment. The Signaling Advisor terminates the Receive side of the Bearer

and generates V.35/RS-449/RS-232 compatible signals on the Transmit side. Maximum

cable length depends on cable quality and will typically be >15 m (RS-232), >1200 m

(RS-449) and >100 m (V.35)

For more information on configuring the Signaling Advisors V.35/RS-449/RS-232

bearer settings in Emulate mode, refer to the instruments On-Line Help.

Verifying Correct Operation


Description

You verify correct operation in Post Capture mode, by selecting All Tests from the

Signaling Advisors built-in Self Test function. When you select All Tests, the

program automatically detects which interface module(s) are housed in the Signaling

Advisor, it then selects and runs the appropriate self tests. It takes approximately 15

minutes to verify each interface module. The default settings are used which means

tests will continue to completion (even if an error is detected), and all results (Pass or

Fail) will be logged to disk.

For a detailed description of Self Test, refer to the instruments On-Line Help.

CAUTION To prevent network disruptions, ensure the Signaling Advisor is disconnected from

your network before you run Self Tests.

Verification Prerequisites

During Self Test you will be prompted to fit external loopback cables.

To minimize verification time ensure that you have following cables available before

you start the Self Test:

Self Test Loopback connector, part number Agilent J4204A.

Clock loopback cable (connects to the Signaling Advisor CLOCK/TRIG IN and

OUT ports), part number Agilent 8120-8820.

Telephone handset (this is an optional connection), part number Agilent 15722A.

ESD Precautions

ESD Precautions

CAUTION When making connections to the modules, review Connecting Interface Modules to

Bearers, Page 7.

The module contains components sensitive to electrostatic discharge.

To prevent component damage, carefully follow the handling precautions presentedbelow.

The smallest static voltage most people can feel is about 3500 volts. It takes less than

one tenth of that (about 300 volts) to destroy or severely damage static sensitive

circuits. Often, static damage does not immediately cause a malfunction but

significantly reduces the components life. Adhering to the following precautions will

reduce the risk of static discharge damage.

Keep the module in its conductive storage box when not installed in the Signaling

Advisor. Save the box for future storage of the module.

Before handling the module, select a work area where potential static sources are

minimized. Avoid working in carpeted areas and non-conductive chairs. Keep body

movement to a minimum. Agilent recommends that you use a controlled static work-

station.

Handle the module by its front-panel. Avoid touching any components or edge con-

nectors. When you install the module, keep one hand in contact with the protectivebag as you pick up the module with your other hand. Then, before installing the mod-

ule, ensure that you are grounded or make contact with the metal surface of the Sig-

naling Advisor with your free hand to bring you, the module, and the Signaling

Advisor to the same static potential. This also applies whenever you connect/dis-

connect cables on the front-panel.

Cleaning the Product

Use a soft, clean damp cloth to clean the outer surfaces.
