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 to four 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


NOTE Beginning January 2002, all shipments of this interface module will be supplied with

BNC connectors. Information about Lemo connectors and cabling are provided in

this manual for reference only.

Connections to the network are made with the eight Lemo connectors or eight BNC

connectors on the interface module. Each pair of connectors provides a full duplex link.

BNC Connectors

Lemo Connectors

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 23.

RXa Ports - Receive E1 unbalanced signals.

RXb/TX Ports - Receive E1 unbalanced signals in Monitor mode, and transmit E1unbalanced signals in Emulate mode.

Connecting to a Protected Monitor Point

Set the Signaling Advisor bearer operating mode to 20 30 dB Terminated Monitor

when connecting to a monitor point that attenuates the line signal by 20 to 30 dB. The

Signaling Advisor terminates the cable from the monitor point properly and causes

minimal reflections. Maximum cable length depends on cable quality and is specified

as 6 dB loss at 1024 kHz, typically this will be more than 100 m. For more information

on configuring E1 bearer settings, refer to the instruments On-Line Help.

Connecting to an Unprotected Monitor Point

Set the Signaling Advisor bearer operating mode to Bridged 2k4 ohms when

connecting directly to an active line (the high input impedance allows you to make the

connection without affecting the signal). The cable length from the Signaling Advisor

to the line being monitored should not exceed 3 m (longer cables cause reflections

which may produce errors and lead to alarms).

For more information on configuring E1 bearer settings, refer to the instruments On-

Line Help.

CAUTION Do not connect to an unprotected monitor point when the Signaling Advisor bearer

operating mode is set to 0 dB or 20 30 dB Terminated Monitor. This will load the

network.

Terminating a Link in Monitor Mode

If you need to use the Signaling Advisor to terminate a link before you can monitor

data, then set the Signaling Advisor bearer operating mode to 0 dB Terminated

Monitor. Maximum cable length depends on cable quality and will typically beseveral hundred meters.

For more information on configuring the Signaling Advisors E1 bearer settings in

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

Connecting for End Emulation

Set the Signaling Advisor bearer operating mode to End Emulate when you

want to send/receive messages to/from Network Equipment. The Signaling

Advisor terminates the Receive side of the Bearer and generates E1 signals on

the Transmit side. Maximum cable length depends on cable quality and will

typically be several hundred meters.

For more information on configuring the Signaling Advisors E1 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:

E1 loopback cable(s), part number Agilent 8120-2682 (BNC connectors) or Agilent

15981-60001 (Lemo connectors).

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.

Web Site for Additional Product Information

Use a layer of shock absorbing material 70 to 100 mm (3 to 4 inch) thick, around all

sides of the instrument to provide firm cushioning and prevent movement inside thecontainer. Do not rely on pellets for shock absorption, as during transit the

instrument will sink to the bottom of the pellets.

Seal shipping container securely.
