Revision 1.8 P/N 90023363
Parameters:
<cid> (PDP Context Identifier) a numeric parameter which
specifies a particular PDP context definition. The parameter
is local to the TE-MT interface and is used in other PDP
context-related commands. The range of permitted values
(minimum value = 1) is returned by the test form of the
command.
<PDP_type> (Packet Data Protocol type) a string parameter which
specifies the type of packet data protocol X25 ITU-T/CCITT
X.25 layer 3 IP Internet Protocol (IETF STD 5) OSPIH
Internet Hosted Octet Stream Protocol PPP Point to Point
Protocol (IETF STD 51)
<APN> (Access Point Name) a string parameter which is a logical
name that is used to select the GGSN or the external
packet data network. If the value is null or omitted, then the
subscription value will be requested.
<PDP_addr> a string parameter that identifies the MT in the address
space applicable to the PDP. If the value is null or omitted,
then a value may be provided by the TE during the PDP
startup procedure or, failing that, a dynamic address will be
requested. The read form of the command will continue to
return the null string even if an address has been allocated
during the PDP startup procedure. The allocated address
may be read using the +CGPADDR command.
<d_comp> a numeric parameter that controls PDP data compression.
0 off (default if value is omitted)
1 on Other values are reserved
At present only one data compression algorithm (V.42bis) is provided in
SNDCP. If and when other algorithms become available, a command will be
provided to select one or more of these.
<h_comp> a numeric parameter that controls PDP header
compression.
0 off (default if value is omitted)
1 on (other values are reserved)
<pd1>,…<pdN> zero to N string parameters whose meanings are
specific to the <PDP_type>. For PDP type
OSP:IHOSS the following parameters are defined:
<pd1> = <host> the fully formed domain name extended
hostname of the Internet host
<pd2> = <port> the TCP or UDP port on the Internet host
<pd3> = <protocol> the protocol to be used over IP on the
Internet - "TCP" or "UDP
