E.
Data Port 2 (AUX2): Synchronous/asynchronous data port. In asynchronous communication, you could
implement asynchronous data transmission which data rate is smaller than or equal to 19.2Kbps via this
port. In synchronous data transmission, this port would be a 64Kbps channel which customer could
implement RS-422 data transmission via this port. This RS-422 is a contradirection channel which
input/output clock both comes from IDU. When local equipment should communicate with remote site
equipment for simple data file transmission or online text communication, this port could be used.
F.
String Port (NMS2): This port is for interconnection of NMS1 & NMS2 port between two equipments, or
between computer & NMS2 port. It also could be used as a connection port for modem which allows
customer to implement remote access. When there are more than two sets of equipments in the local
stations, connect the IDU-NMS2 of this equipment to the IDU-NMS1 of the other equipment. When the
NMS2 are connected, only one of the service phones is working.
G.
Monitor port (NMS1): This port is for cascading connection between two equipments, or PPP network
connection between computer & NMS1 port. Connect the COM1 or COM2 (RS-232) of the computer to
this port or act as a connection between more stations.
H.
IF Port (N-Type 50 ): Transmission includes transmitter 310MHz, receiver 70MHz, monitor
11.0592MHz, DC -48V/0.5A. Maximum transmission of 100m possible when using RG-6 cable.
Maximum transmission 200m possible when using RG-8 cable.
