Name
Name of the modem. This name is for reference only and will appear in the
following places:
■833IS Manager statistics.
■833IS Front Panel.
■SNMP Modem MIB, field mdmIDProductDetails.
Maximum length is 16 characters. The default name is automatically generated as
SxMy, where x = slot number of the Modem card, and y = Modem number.
Modify
Check this box if you wish to override the default modem initialization. You may
wish to do this if you have users dialing in with old modems that cannot negotiate
correctly with current modems.
Modem Initialization String
Enter the modem initialization string here. This string will be attached to the end of
the default modem initialization. Please note that the base modem initialization will
have reset the modem. It is not recommended that you do another modem reset (do
not perform an AT&F), because there are additional parameters required for the
correct operation of the 833IS. You should minimize the changes to only those items
required for your environment. All commands must be valid AT commands as
defined in Appendix 2.
Be very careful if you are overriding the default modem string. Setting this
improperly could prevent the modem from receiving incoming calls entirely. It is
strongly recommended that you place any modems with modified initialization into
a separate modem group. See section see “Group Settings” on page 182.
The modem behaves differently from a stand-alone modem because it does not
directly interface to the telephone line. Phone call handling is done by the ISDN BRI
interface. Once the call is established it is switched to the modem. Therefore, modem
commands that do line control (such as ATA, ATH) may behave slightly different
then they would in the case of a modem which is connected to a telephone line.
