CHAPTER 2

System Setup

Note: If you use an external GSM modem, you can add

CBST=71,0,1 to the initialization command to tell the GSM

modem to use the fully digital V110 mode. This makes

setting up a connection much faster than with the standard

modem emulation.

b. The Modem chat timeout refers to an internal parameter

(the time-out associated with the communication

between the A733 microprocessor and the on board

GSM module); it should not be changed.

c. The Cancel the call... parameter defines how long is the

modem allowed to negotiate with its peer to establish a

connection; in some cases you may need to increase this

value if your peer modem has difficulties to connect.

However, a higher value for this parameter might lead to

higher connection costs.

Note: The above is valid only in cases of failure: normally the

modems connect in typically 40 seconds (10 seconds for

GSM modems using the V110 mode), therefore reducing

this value will have no effects on the connection costs.

d. The PIN for SIM card entry allows you to enter the PIN

for the SIM card in the external GSM Modem if there is

no valid PIN set. After a successful update, the text in this

entry field will change to accepted (reading back the PIN

setting is not possible due to safety reasons).

Note: This setting is disabled while the modem is in use. You

cannot change this setting while you are dialling in over the

modem.

e. The Country Setting combo-box allows you to configure

the country code for the built-in Worldmodem. For the

CTR21 or an external modem, this combo-box is

disabled.

Note: This setting is disabled while the modem is in use. You

cannot change this setting while you are dialling in over the

modem.

f. The Log combo-box allows you to select between

logging only failed calls (default), or all calls. Note that at

most the last 100 calls are logged, all older entries are

automatically deleted. You can check the log file via the

menu FileModem log.
