TDM board is registered with own slot number. It is registered automatically without any
configuration.
If the station is assigned to Master or Slave by linked station, the bracket ‘[M] or [S]’ will be
displayed by the station number in PGM 101, 103, 105, 124 of Web page.
To register IP device:
As Gateway/board and terminals are registered to the iPECS, a slot number is assigned, which
indicates the order of registration. Also, based on the type of device (CO Gateway/board,
Terminal or Station board) the system assigns a logical Sequence Number. Thus, Sequence
Numbers for CO Gateway/board, Terminals are independently assigned based on the type of
Gateway/board. These Sequence Numbers are employed to provide a relationship between the
physical MAC address and the logical port numbers of the device.
The system may assign a default private IP address to each Sequence Number. If desired, this
program may be used to modify the assigned IP address for each Gateway/board and iPECS
Phone.
Each Gateway/board and terminal can be assigned for “Direct Send”. With Direct Send enabled,
the system will employ the Ethernet MAC address of the device to send iPECS protocol
messages to the device. This reduces the overall LAN traffic by eliminating the need for IP
address headers in the messages.
The system normally employs IP multi-cast protocol to respond to a registration request from a
Gateway/board or terminal. When the device is separated from the system by a router, the
system must use the IP uni-cast protocol. This is established by the “Local Device” assignment.
When disabled (Off), the system will send an IP uni-cast message to the device in response to a
registration request.
