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 Appendix B) 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.
