13. IP-FAX communication specifications
13.1 IP-MAX communication
(1) IP-MAX communication is IP-FAX board communication which is independent of modem’s
communication speed.
(2) IP-MAX communication declares capability by NSF/NSC signal during IP-FAX board
communication.
(3) IP-MAX communication instructs by NSS signal only when capability is declared by NSF/
NSC signal.
(4) IP-MAX communication declares/designates by the following Bit of NSF/ NSC/ NSS
signal.
13.2 Restrictions in IP-FAX board communication
13.2.1 When IP-FAX board communication is performed, V.34 communication is not allowed.
13.2.1.1 Sending
1. Does not move to V.34 communication when an IP-FAX board sends, even though it
receives ANSam signal. Communicates by DIS (NSF) signal.
2. Does not move to V.34 communication when an IP-FAX board sends, even though V.8 Bit
of receive DIS signal is ON. (CI signal is not sent.)
13.2.1.2 Receiving
1. ANSam signal is not sent when IP-FAX board sends.
2. V.8 Bit of DIS signal is set to OFF when IP-FAX board sends.
13.2.2 In case of communication by IP-FAX board, Oki high speed protocol B is not allowed.
13.2.2.1 Sending
1. In case of communication by IP-FAX board, NSS signal does not assign Oki high speed
protocol B even though NSF signal assigns it.
13.2.2.2 Receiving
1. In case of communication by IP-FAX board, NSF signal does not assign Oki high speed
protocol B.
13.2.3 NSF RMCS Bit
At the time of NSF sending, it is sent with RMCS bit: OFF.
