MODEM SETUP

If a pair of modems is used to connect the SIM to the

System Manager, the modems must be configured for the

type of audio circuit that they are connected to. The

19A149786 drawing in the modem maintenance manual,

LBI-33031, lists parameter sets for several applications of

the ZyXEL U-1496 modem (standard modem supplied with

the SIM Modem Shelf, when ordered). For a 4-wire leased

telephone line application, use the parameter set for the “Site

Controller 4-Wire Leased Line” for the SIM end, and the

parameters set for the “System Manager 4-Wire Leased Line

(to site)” for the System Manager end. For a 2-wire dialup

telephone line application, use the parameter set for the “Site

Controller 2-Wire Dialup Line” for the SIM end, and the

parameter set for the “System Manager 2-Wire Dialup Line

(to site)” for the System Manager end. For other audio

circuit applications, determine the correct parameter set

from the ZyXEL manual supplied with the modem.

Use the following procedure to make changes to the

parameters in the ZyXEL U-1496 modem:

1. Press the up arrow key to enter the configuration

mode.

2. Press the down arrow key to go to a parameter

group.

3. Press the left or right arrow key to select the

desired parameter group.

4. Press the down arrow key to go to a parameter in

the selected parameter group.

5. Press the left or right arrow key to select the

desired parameter.

6. Press the down arrow key to view the current value

for the selected parameter.

7. If the current value is the desired value, press the

up arrow key and go on to the next parameter. If

the current value is not the desired value, press the

left or right arrow key to select the desired value.

8. When the desired value has been selected, press the

down arrow key to change the parameter to the

selected value and go on to the next parameter.

9. If the next parameter is in this group of parameters,

return to step 5. If the next parameter is not in this

group of parameters, press the up arrow key and

return to step 3.

After all parameters in all parameter groups have been

verified or reconfigured, use following procedure to save the

changes:

1. Press the up arrow key until a parameter group is

selected.

2. Press the right arrow key until “SAVE TO =

PROFILE 0” is displayed.

3. Press the down arrow key twice.

4. Press the right arrow key until “RESET =

PROFILE 0” is displayed.

5. Press the down arrow key.

SIM SETUP

Regardless of whether the SIM was installed at the site

or the factory, you must program the SIM to obtain the

desired operational characteristics for your specific system.

Note that in the character strings used to program

the SIM, the symbol

∧∧

is used for a single space

between characters. Also note that letters used in

these character strings are case sensitive.

NOTE

Programming Setup

Use the following procedure to set up a customer-

supplied IBM-compatible PC with terminal emulation

software (or a dumb terminal).

1. Configure PC (or Terminal): Select the serial COM

port to be used (generally COM1 or COM2), and

configure as follows:

Baud Rate = 19,200

Start Bits = 1

Data Bits = 8

Stop Bits = 1

Parity Bits = None

2. Connect PC (or Terminal): Connect the supplied

programming cable (Ericsson # RPM 113 2514)

from J4 on the front of the SIM to the serial COM

port of the PC (or terminal), as shown in Figure 4.

If the serial COM port of the PC (or terminal) is not

equipped with a male 9-pin, D-subminiature (DB-

9) connector, a customer-supplied adapter will be

required.
