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)
