2. +WS174=n where n indicates the application of the channel side (A or B) assigned by your
CDPD provider. Values for n are:
1 – A side preferred,
2 – B side preferred,
3 – A side only,
4 – B side only.
3. Optionally configure desired cellular channel restrictions:
+WPSPNI=n[,n[,…n]] where n is a SPNI value and multiple values are separated by
commas. The list of parameters provided will replace any previous table. You cannot append
entries to an existing table. You may enter up to 10 values in the table. By entering one or
more SPNI values, the SPNI matching feature is automatically enabled. In most situations the
use of SPNI matching is not required.

8.2.2.
Registration and Sleep Mode
Determine and set the registration method and whether or not to use the modem’s sleep capability.
4. Optionally set manual registration mode. The default from the factory, and the recommended
option, is to use automatic registration. If manual registration is required set +WS173=0. If
this is used, you may also wish to change the Registration Wait Time with +WS198=n where
n is the time in seconds to allow the modem to register. The default is 30 seconds.

n is the time in seconds to allow the modem to register. The default is 30 seconds.
If TCP is being used without automatic registration, you should consider both the
Registration Wait Time (+WS198) and the TCP PAD Timeout (S7). The TCP PAD
Timeout is the amount of time allowed to handshake a session open (or closed). Both
timers start when the dial command is issued so the TCP Timeout must allow for the
registration time.

5. Optionally set the modem to use sleep mode. The default has sleep disabled (all settings to 0).
+WS175=n where n is the idle time in seconds before CDPD sleep is engaged;
S31=1 to also apply Logic Sleep, or S31=2 to apply logic deep sleep.
S31=1 to also apply Logic Sleep, or S31=2 to apply logic deep sleep.
Sleep must be used with caution in TCP applications to prevent unnecessary
retransmissions or possibly dropped sessions.

8.2.3. Service
Options
Select either UDP or TCP protocol, and whether to act as a server or a client.
6. +WS45=0 to select UDP service; or
+WS45=1 to select TCP. The default from the factory is 3 – SLIP.
7. For Server operation:
a. Set the listening port with +WS212=port where port is the number from 1025 to 4999.
The default is 2100.
b. For UDP, optionally enable the UDP Server Receive Lock by setting a timeout in register
+WS217. This is highly recommended.
c. Optionally configure Friends List entries to limit access. See Section 5.1 above.
d. Optionally disable auto-answer using S0=0 (the default is enabled).
