TDM board is registered with its 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 the Web page.
To register IP device:
As Gateway/board and terminals are registered to the iPECS, a slot number is assigned, indicating the
registration order.
Also, based on the type of device (CO Gateway/board, Terminal, or Station board).
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 Gateway/board or terminal registration
request.
When a router separates the device, the system must use the IP unicast protocol. The “Local Device”
assignment establishes this. When disabled (Off), the system will send an IP unicast message to the device in
response to a registration request.
