|The Wireless Communications Transfer
Protocol (WCTP) was designed to simplify the transmission of
alphanumeric and binary messages from automated, server-based
systems to and from 2-way devices. WCTP is the most technically
preferred method of connecting to the American Messaging paging
network by third-party servers and software clients. This is
because WCTP provides certain features, including the highest
level of security, not presently supported by SNPP.

WCTP and XML
WCTP was developed based on widely accepted Internet protocols
and standards including HTML and XML. You should be familiar
with these standards before attempting to implement a WCTP
connection to the American Messaging paging network. Furthermore,
we have not implemented the entire suite of commands and controls
associated with WCTP version 1.2 or later, so you should read
this document carefully to ensure that your desired implementation
is supported by our network. Because WCTP uses XML as its
communication language, WCTP operations must be formatted
in accordance with the XML 1.0 specification. This requires
that all operations be "well-formed" and “valid” according
to the WCTP Data Type Definition (DTD file specified by American Messaging). The meaning of well formed and
valid is described in the XML specifications (see http://www.w3.org/XML
for more information on XML and well formed and valid operations).
Firewall and TCP/IP Ports
Additionally, since WCTP rides on HTML, you can connect to our
network using port 80 through the Internet. Moreover, if you
need a secure connection, you connect using SSL through port
443. Both of these ports are generally open through most enterprise
firewalls, which should allow developers to implement a solution
without changing corporate firewall settings.
Benefits Over SNPP
In comparison to other protocols such as SNPP, WCTP is more
robust but more difficult to implement. Our implementation of
WCTP requires that your solution act as a WCTP client to our
WCTP host. There are some standardized clients available that
will communicate using the WCTP protocol. However, because of
WCTP’s flexibility and rich feature set, custom applications
can exploit it capabilities far beyond what an off-the-shelf
application will provide. In addition to providing a secure
connection to the American Messaging paging network, using WCTP
enables you to obtain responses from 2-way paging devices, provided
that the original message was sent via WCTP. Note, your WCTP
client is required to “poll” our WCTP host for any expected
response(s). WCTP is the preferred connection method for time
bound, full 2-way communications between our paging devices
and your servers.
Supported WCTP Operations

operations can be found at : http://wctp.myairmail.com/wctp/wctp-dtd-v1r1.dtd.
