Permissive. The answering device must be capable of generating the 
2.1 KHz tone needed to disable any echo cancellers on the line. Consult 
with the owner of the destination equipment to see whether it has this 
capability.

To configure this feature, you must define the DialNoList entry with a type 
of BriV, by using:

ADD !<port> -POrt DialNoList "<phone number>" Type=BriV

The Baud specifier in the ADD command, although not disallowed, is 
ignored if present. Data sent over the B channel will only be sent at 56 
Kbps.

To place a data over voice call on port 2 to an ISP with the phone number 
453-4444, enter:

There are two types of ISDN leased lines in Germany: Digi64S and 
Digi64S2. Digi64S can run only on the B1 channel, but Digi64S2 can run 
on the B1 and B2 channels.

To enable the Digi64S2 feature, follow these steps:

1 Set the LineType parameter to Digi64S2 by entering:

(abbreviated d64s2)

2 Toggle the respective paths by entering:

Path 2.1 is mapped to the B1 channel and path 2.2 is mapped to the B2 
channel. This mapping is not interchangeable.

If one of the paths is set to Digi64S2, the path in the same connector line 
is also set to Digi64S2. Mixtures of line types within a single connector 
are not supported.
