2. IP address of a router or server to ping when testing the connection. This may be a Domain
Name Server (DNS).
Both of the above items are in the form of an IP number. This is made up of four numbers
ranging in value from 0 to 255, separated with periods (sample: 192.168.0.9)
3. Side designator, A or B. This determines the channels used by your CDPD service provider.
4. SPNI number of the provider. This is optional. The Service Provider Network Identifier
(SPNI) can be used to restrict the modem to accepting service from a limited list of providers
and can help speed up cellular channel acquisition and registration.
This information will be required when configuring your modem for CDPD registration either
with WirelessExpert or AT commands.
2.2.2. CSC (AMPS)
To use your SB320 modem in CSC mode it must be activated with a cellular phone service
provider. To register your modem for CSC activation, contact your local cellular carrier.
Give the service provider the Electronic Serial Number (ESN). This is the identification number
of the radio/modem. A Sierra Wireless ESN has the following format: 206-xxxxxxxx. Look for
this number on the back of your modem and on a label affixed to the outside of the package that
the modem was shipped in. The number is also available by querying the modem with the
AT+WVESN command.
The cellular service provider supplies the following:
1. A Number Assignment Module (NAM). This is your cellular telephone number and your
Home System ID (SID).
2. Side designator, A or B. This determines the channels used by your service provider.
This information will be required when configuring your modem for CSC mode use either with
WirelessExpert or AT commands.
2.2.3. Wireline
There are no particular setup issues to configure your SB320 modem for use in wireline mode. It
is required that the telephone line be analogue and not digital as found on some PBX systems.
2.3. Setup Considerations
2.3.1. Host Computer Terminal
You will require a PC with a communications program capable of operating in ASCII terminal
emulation mode. This allows the PC to function as a terminal attached to the modem and permits
the entering of AT commands required for modem setup and diagnostics. We recommend that the
program chosen be capable of logging terminal communications activity to a file for later analysis
or printout in the event that technical support is required.
For IBM PC-compatibles, Windows Terminal, Hyperterminal, Procomm, and Kermit are all
acceptable. Note that early versions of Hyperterminal do not allow you to send SLIP framing
characters to the modem, preventing use of the escape sequence. This is corrected in later
versions.
A 9-pin D connector RS-232 serial cable (part number 006.0011) is provided with the OEM
Developer’s Kit for connecting the PC host to the Multipurpose Interface Board.
