3. OPTIONAL EQUIPMENT
The actual repeater configuration can be seen at the configuration list which is part of
the delivery.
3.1. MODEM
The modem option enables the provider to set parameters and to query the status of
each repeater remotely. Furthermore, the modem can be set to send all occurred
alarms of the repeater directly to a provider’s terminal, e.g. to the OMC. This can be
done either via a wireless modem or a PSTN modem (Public Switched Telephone
Network). Thus, the alarms can be evaluated and eliminated promptly. It is possible
to install the wireless modem or the PSTN modem on site!
∫ Check the communication mode between the modem and the terminal. If
necessary, set the following parameters:
Bit rate / bit per second: 9600 baud Number of data bit: 8 bit
Parity bit: No parity Stopbit: 1 stopbit
These settings can only be changed after connection to the terminal. If a different
modem is required or if the quality of the line does not allow to use the set
parameters, the settings have to be changed in PC mode. The same applies for all
other parameters which can be set previously for modem mode by software.
3.1.1. Initstrings
Depending on the provider’s network and the used modem type, it is necessary to
adjust the initstring. The following initstrings are factory set:
Modem Network Initstring
Siemens M1* GSM900 ATE0S7=60S0=2\N6
Siemens M20* GSM900 ATZE0S0=2&S0+IFC=0,0+CBST=7,0,1
Motorola Mobile
MR30 “Surf–Pro”**
PCS1900 AT*P1&F&K4E0S0=2\N0+CBST=7,0,1
MIKOM MO4000 GSM900/1800 ATE0S7=60S0=2;+CBST=7,0,1
PCMCIA-modem PSTN AT&FE0S0=2
* The Siemens M1 modem is no longer available and is replaced by the Siemens M20. In future, it is
assigned to replace all wireless modems working in GSM900/GSM1800 networks by the new MIKOM
modem MO4000.
