Parameter Description
If PAP or CHAP has been selected then this is the
password.
A numeric string (ex: "54311") that protects the SIM
card from being used by unauthorized persons.

When establishing a client connection (the CNI4
calls a server), it must assign itself a port number
which will be reported to the host server.
If the Source Port Ending Number is the same, then
the customer can choose to use the same source
port number for each call.
If the Source Port Ending Number is greater, then
the customer can use a range of port numbers. The
first call will use the Source Port Starting Number.
For each subsequent call, the source port number
will be incremented until it is greater than the
Source Port Ending Number. Once greater, the
sequence will start over with the Source Port
Starting Number.
Example:
Source Port range = 50000 - 50010
1st Call uses 50000
2nd Call uses 50001
11th Call uses 50010
12th Call uses 50000 and so on
This defines the maximum data portion of the
TCP/IP packet, which is usually referred to as the
Maximum Segment Size, or MSS. Maximum is
65535 bytes. Legacy Ethernet v2 segment sizes
were limited to about 1460 bytes.
