Ease Of Installation; Isdn Basic Rate Interface (Bri); Isdn Leased Line - Planet IRT-1001ST User Manual

Ease of Installation

Your IRT-1001 or IRT-1002 is a self-contained unit that is quick and
easy to install. Physically, it resembles an external modem except for
the fact that it is a router and uses an Ethernet cable to connect to the
host network.

ISDN Basic Rate Interface (BRI)

Using a standard S/T or U Interface (the IRT-1001ST and IRT-1002ST
use the S/T interface, while the IRT-1001U and IRT-1002U use the U
interface) the IRT-1001ST and IRT-1002ST support a full range of
switch types. The switch type depends on the CO (Central Office) switch
your ISDN line is connected to. See the ISDN Switch Types chapter for
more information on North American, European, and Asian ISDN
firmware and switch types supported by these routers.
The two B-channels can be used independently for two destinations. Or
they can be bundled for one connection to support bandwidth-on-
demand.

ISDN Leased Line

If the router is set up for an ISDN leased line (that is, if any option but
"Switch/Switch" or "Switch/Unused" is selected for the B Channel [Usage
control] in setup menu 2, [ISDN Setup], and the [Transfer Type control]
is set to Leased in either setup menu 4, [Internet Access Setup], or
setup menu 11.1, [Remote Node Profile]), the router will automatically
initialize the leased-line connection each time it is powered up or setup
menu 2, 4, or 11.1 is saved.
The IRT-1001ST and IRT-1002ST implement the PPP echo mechanism
for verifying ISDN leased line status. The setting of the Idle Timeout
control in setup menu 11.1 will be used as the interval between two
LCP_Echo_Req messages. It is supposed that there exists an echo
reply corresponding to an echo request. Whenever an echo request is
sent, the counter will be incremented by one.
