Fax And Modem Over Ip - NEC NEAX 2000 IPS Reference Manual

Chapter 13 Voice Over IP (VoIP)

FAX and Modem over IP

This feature allows the system to transmit facsimile or modem communications over IP
network, via Local Area Networks (LAN) and corporate Wide Area Network (WAN). Since PBX
regards facsimile and modem equipment as one of ordinary telephones, IP Packet
Assembler/Disassembler (IP-PAD) and Voice Compression Trunk (VCT) are required for
facsimile uses over IP network same as legacy stations. The facsimile transmission procedure
(T.30 or G.711/G.726 pass-through) is supported with IP-PAD/VCT. The following figure shows
a typical configuration of facsimile or modem use on Peer-to-Peer CCIS network.
