voltage could damage the unit.
 
Connecting to the WAN
 
If your OfficeConnect Remote unit is fitted with a WAN 
 
port, you can connect to a WAN Network Terminating 
 
Unit (NTU) fitted by your WAN service supplier. Using a 
 
suitable WAN cable (as described in 
 
 
 
connect one end to the WAN port on the 
 
OfficeConnect Remote unit and the other to the NTU.
 
Connecting to the VOICE Port
 
If your OfficeConnect Remote is fitted with a Voice 
 
port, then a standard telephone handset or other 
 
analog telephony equipment, such as a a fax or 
 
answering machine, can be connected to the port 
 
marked VOICE if required. This port can also be used 
 
to connect the OfficeConnect fax server to ISDN.
 
Some service providers offer Basic Rate ISDN 
 
connections with a single B-channel. If you connect a 
 
handset to a unit connected to this type of ISDN 
 
service, you cannot pass data while the voice port is 
 
in use. We recommend that you only connect voice 
 
equipment to ISDN services offering the standard 
 
2 B-channel Basic Rate service.
