Setting the Line Coding
On AN or ASN routers, and on a router with an Octal Sync link module, you can
specify the line coding of the physical synchronous line to match the line coding
of a device at the other end of the line. Specify the line coding as follows:
• Select NRZ (the default) for nonreturn to zero coding.
• Select NRZI for nonreturn to zero inverted coding.
• Select NRZI Mark for nonreturn to zero inverted mark coding.
Set the line coding for the interface.
Using the BCC
sync-line-coding
variable
For example:
sync/4/1# sync-line-coding nrz
sync/4/1# sync-line-coding nrzi
sync/4/1# sync-line-coding nrzimark
Using Site Manager
See the Sync Line Coding parameter on page A-70 for information.
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 2-5)
