How To Use Hayes Compatible Packet Data mode
Some older legacy DTE equipment that the iO1500R may be interfaced to may not
have a TCP/IP stack. These devices use Hayes Module AT commands to
communicate. A non-IP interface was implemented inside the module to work with
these legacy DTEs using a simulation of Circuit Data Over Packet Data. Terminals
that are using AT-Module protocol will be thus be able to communicate with the
iDEN data modules and use the iDEN Packet Data services. This capability is only
available in the iO1500R and not the standard iDEN modules.
Circuit data over Packet data will operate as follows:
The non-IP DTE will use the AT command set described in the TIA/EIA-602
standard for Circuit Switched Data transmissions, with the following modification:
ATD<IP_address..Port_Number>
instead of :
ATD<Phone_Number>
Note: There is no Fax support while in Hayes compatible packet data mode.
An AT command interpreter, implemented in the module software, receives the
ATD<IP_address: Port_Number> command and transfers it to the Packet
Assembler/Disassembler (PAD) which prepare the data in a mobile TCP/IP format
which is recognized and transferable by the iDEN infrastructure.
The end result is circuit data interface with packet data over the air.
The user gets circuit data interface for it’s dumb terminals with the response time and
data rates of packet data.
