Figure 5-2. KG84A Network Configuration
The Bay Networks router attaches to the KG84A device via a modified V.35
synchronous cable. The encryption/decryption process is usually transparent to
the router. However, occasionally two KG84A devices can lose cryptographic
synchronization. When this occurs, the modified cable allows the router to initiate
cryptographic resynchronization. The modified cable also allows the router to
detect and monitor the local KG84A device resynchronization, whether the
resynchronization is initiated locally or by a remote KG84A device.
The router detects the loss of synchronization between KG84A devices by
monitoring the number of FCS errors and valid frames received. If the router
detects FCS errors, and it does not receive a valid frame within a time you specify,
the router software requests resynchronization. The router also requests
resynchronization if it determines that the previous resynchronization request did
not complete before the time you specified.
You can also force a resynchronization of the local KG84A device by pressing its
RESYNC button. The router can detect this type of remote resynchronization
also, and can request a new resynchronization if one does not complete in the
configured time period.
Configure KG84A support on synchronous lines that connect to KG84A
cryptographic devices, using the following parameters in the Edit SYNC
Parameters window.
KG84A Cycle
KG84A Sync Loss Interval
KG84A Remote Resync Wait
KG84A Sync Pulse
Note: Be sure to also set the RTS Enable parameter to Enable.
