Customizing Synchronous and Asynchronous Lines

Figure 4-2. Satellite Broadcast (Sample Topology)

To avoid such confusion, assign unique addresses to each end of a point-to-point

circuit using the Local Address and Remote Address parameters in the Edit SYNC

Parameters window (r

efer to Figure 4-1). Be sure to reverse the local and remote

addresses when you conﬁgure the other end of the point-to-point circuit. For

example, the local address for router A becomes the remote address for router X,

and the remote address for router A becomes the local address for router X.

KG84A Support

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 (F

igure 4-3).
