ISDN can also be used to make voice calls
using the
OfficeConnect Remote
from an ordinary telephone
handset, connect faxes and other similar office
equipment.
All OfficeConnect Remote models have
facilities for ISDN data transmission. Some models
have an additional port for voice calls and/or a port
to handle a third category of connection over a
serial WAN port.
The WAN port connects to a permanent leased line,
also available from your telephone carrier
organization. Leased lines are available to work at a
range of speeds which incur higher costs the higher
the line speed. The benefit of leased lines is their
permanenc
e
and fixed cost. No dialling is required
but unlike ISDN you pay a fixed cost regardless of
whether you transfer little data or high volumes of
data 24 hours a day.
Overall ISDN is probably the most cost effective
solution for small businesses. However, if your
requirements to move data between sites is likely to
increase you should consider purchasing the
OfficeConnect Remote model fitted with both ISDN
and WAN ports to ensure increased flexibility. The
range of OfficeConnect Remote units is as follows:

transfer facilities, this model has a Voice port allowing a
telephone (or other equipment such as a Fax) to
communicate via ISDN.
■
OfficeConnect Remote 530
–
This model has the
ISDN and Voice port facilities
and additionally the
ability to connect via a WAN port to a serial leased

All of the above models are available with
U
or
S
ISDN interfaces.
Typically, the OfficeConnect Remote is used to
interconnect LANs running protocols such as
Transmission Control Protocol/Internet Protocol
(TCP/IP) or Novell Internetwork Packet Exchange (IPX).
Offering full LAN-to-LAN connectivity at speeds up to
64 Kilobits per second (Kbps) on each ISDN channel
and up to2 Megabits per second (Mbps) on the WAN
