Customizing Synchronous and Asynchronous Interfaces
114078 Rev. A 5-23
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 for Non-Return to Zero coding.
• Select NRZI for Non-Return to Zero Inverted coding.
• Select NRZI Mark for Non-Return to Zero Inverted Mark coding.
Line coding is NRZ by default.
You can set the line coding for the interface.
Specifying the Network Link Level
By default, the Network Link Level for this synchronous point-to-point
connection is NET2.
Change this parameter to GOSIP when this synchronous point-to-point
connection is part of a GOSIP-compliant network (such as DOD).
Change this parameter to SYNC_TYPE_C03 when you are running X.25 on a
synchronous board with the MK-5025 C03 chip.
You can set the link level for the interface.
Note: See “Configuring KG84A Security” for information about the KG84A
parameters.
