Data
The data protocol must match the remote ISDN device to which you are going to connect.
Your options are ‘PPP’, ‘MultiLink PPP’, ‘MultiLink PPP with BACP’, ‘MultiLink PPP with AODI’,
‘V.110’, and ‘V.120’.
PPP’ operates on a single ISDN channel. Since two ISDN channels are available, the
DIVAT/A can support two PPP connections at the same time. This is useful if you
need to have two connections running concurrently. For example, you could use one
channel to maintain a connection to the Internet, and another to connect to a
remote corporate network. Or perhaps you wish to support incoming data calls, as a
PPP connection will never be disconnected to allow an incoming or outgoing analog
call. Note that if two PPP connections are active, no analog calls can be made.
MultiLink PPP When you activate Multilink PPP, the DIVAT/A combines both ISDN B-channels into a
single 128 kbps communications link. Both channels remain in use as long as long as
the connection is active, which may result in excessive ISDN connection charges if
the link is frequently idle.
Multilink PPP reserves both ISDN B-channels for its exclusive use. If you use Multilink
PPP, you will not be able to make or receive other data calls.
Analog calls are governed by a different set of rules. By default, the DIVAT/A is
configured to support call bumping, which causes the DIVAT/A to drop one ISDN
channel when you make or receive an analog call.
This reduces the throughput of the data call to 64 kbps. When the analog call is
done, Multilink PPP re-establishes the second channel, returning the data
connection to 128 kbps.
Only one of the two PHONE ports can be used when a Multilink PPP connection is
active.
V.120 The V.120 protocol, more popular in North America, adapts other transmission rates
to the 64 Kbps ISDN line rate.
V.110 The V.110 protocol, used mostly in Europe, adapts other transmission rates to the
64 Kbps ISDN line rate. V.110 carries asynchronous data rates from 2.4 to 19.2 Kbps.
