The basic subnet IP mask for Class C addresses, which supports the maximum possible number of hosts, 254, is 255.255.
Installation and Operation Manual Appendix C IR-IP Interface Module The default operation is used when the Default Gateway field is blank. Operation with Default Gateway You can instruct IR-IP to send packets with destinations not located on the local LAN to a specific router, which is called the default gateway. The default gateway must be connected to the local LAN. To use this option, enter the IP address of another router attached to the local LAN in the Default Gateway field.

Appendix D IR-G.703/CO Interface Module D.1 Introduction IR-G.703/CO is an interface module for RAD modems, converting G.703 64 kbps codirectional signals to TTL levels. The converted data is sent over the modem link using the modem modulation technique and converted back at the other end into G.703 64 kbps codirectional signals, or into any other digital interface signal possible.
Appendix D IR-G.703/CO Interface Module Note Installation and Operation Manual For the G.703 codirectional interface, byte synchronization is not kept end-toend. A violation bit is inserted every eight bits, but it does not appear in the same location at the remote end. D.2 Selecting the IR-G.703/CO Timing The IR-G.703/CO interface module can operate with EXT or INT/RCV timing to match the clock reference of the ASMi-31 modem.
Installation and Operation Manual Appendix D IR-G.703/CO Interface Module INT/RCV Timing The INT/RCV clock is used in applications where the G.703 codirectional 64 kbps equipment connected to the modem recovers the clock signal from the modem link. This mode is used mainly when the attached equipment has a G.703 codirectional interface, but is not able to produce clock signals. The module has an 8-bit FIFO buffer to compensate for the phase delay introduced by the G.703 device.
