10.1. PABX MANAGEMENT MODE
PABX MANAGEMENT MODE COMMANDS
This mode allows remote access to a PABX Ethernet port through the buffer. It allows commands
to be passed from either the Serial MMI port or the Ethernet MMI port to the PABX Ethernet port.
Command Description
PBXC<port>
The command PBXC<port> is issued to the buffer. The buffer will
attempt to establish a connection to the PABX using the ‘LOG LAN IP
addr’ (command LLI) with the specified port number. When the
connection is established the buffer will respond with:
PMS: Connected <port>
A twenty second timer is started so that if no commands are sent to the
PABX the link will be disconnected with the message:
PMS: Disconnect
PBXM<hex data>
Messages are sent to the PABX using a Hexadecimal ‘PDU’ format
with the PBXM command. This allows any character to be sent from
ASCII 0 to ASCII 255. (0x00 to 0xFF) Example:
PBXM 727001ffffff002200000022FFFFFFFFFFFF
This message is the logon header for a popular PABX.
Responses from to PABX are converted to the same ‘PDU’ format and
prefixed with “PBXR<space>”. Example showing a login rejection
message from a popular PABX:
PBXR 707201000000000000000000000008000000
10.2. TCP CALL-BACK-MODE
TCP Call-Back Mode
This function allows the buffer to create a TCP connection to the TMS server using a specified
port. The connection is attempted to the host that was specified using the TMI command. The
purpose of this is to allow the buffer to tunnel out from behind firewalls when the using UDP LOG
to gather the data. The command to setup this call back link is:
Command Description
TCPC<port>
The response when the connection takes place is:
TCB: Connected <port>
The is an MMI timeout on the Ethernet MMI connection and when this
occurs or when the remote application disconnects a message is
output on the originating port:
TCB: Disconnected
