2.2.3 Physical Interfaces
The DSI SS7HDP board (SS7HDPD4TEW) supports the following physical interfaces:
• Four T1/E1/J1 digital trunk interfaces. See Section 2.2.3.1 below for more detail.
• One 10/100Base-TX Ethernet interface (RJ-45 port)
• H.100 CT Bus interface. See Section 3.4.1 for details on the correct termination
of the CT Bus.
Note: The 10/100Base-TX Ethernet interface is currently not supported.
