Customizing Synchronous and Asynchronous Interfaces
114078 Rev. A 5-27
Setting the B Channel Override
On AN and ANH routers with ISDN support only, you can connect the ISDN
B Channel to a specific serial communications controller (SCC). By default, the
B Channel is determined by the connector.
You can use the Sync B Channel Override parameter to specify which B Channel
this interface is using for ISDN. Select BCHANNEL1 or BCHANNEL2 to
explicitly assign the B Channel. You can set the B channel to
DEFAULT
BCHANNEL1
BCHANNEL2
FLOATINGB
If your ISDN service provider only offers 2B + D service, the FLOATINGB
option enables you to use only one B channel for dial service applications.
Floating B is an alternative if you cannot purchase 1B + D service.
Select FLOATINGB to use only one B Channel of ISDN, which becomes
BCHANNEL1 or BCHANNEL2 depending on the call setup procedures.
COM1 and COM2 become available in this mode.
You can configure the B Channel on an AN or ANH ISDN interface.
Configuring KG84A Security
KG84A is a cryptographic device used to secure data transmitted over a
point-to-point synchronous line.
Bay Networks KG84A support allows the router to use the encryption services of
a KG84A device. In a KG84A configuration, the KG84A device is usually placed
between the router and a modem. The KG84A device acts as the DCE for the
attached router. Another KG84A device must be located at the other end of the
point-to-point connection so that encrypted data can be decrypted
(Figure 5-2).
