3Com NETBuilder SI, SuperStack II manual Example, Toggle the respective paths by entering

Configuring ISDN on the WAN Port (43x, 44x, 53x, and 54x) 73

Permissive. The answering device must be capable of generating the

2.1KHz 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.

Example

To place a data over voice call on port 2 to an ISP with the phone number

453-4444, enter:

ADD !2 -POrt DialNoList "4534444" Type=BriV

Enabling Digi64S2 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:

1Set the LineType parameter to Digi64S2 by entering:

SETDefault !2.1 -PAth LineType = Digi64S2 (abbreviated d64s2)

SETDefault !2.2 -PAth LineType = Digi64S2

2Toggle the respective paths by entering:

SETDefault !2.1 -PAth cont=e

SETDefault !2.2 -PAth cont=e

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.
