28 WAN Probe/Device Setup
Digital DS3/E3/HSSI Probe Settings
Digital T1/E1 Probe Settings
Setting Explanation
WAN/Frame Relay Type Choose DS3 (T3) , E3 or HSSI to match the type of link you are
analyzing.
Encapsulation You must set this to match the settings on the frame relay
CSU/DSU. The encapsulation options are:
-ATM-DXI - ATM Data Exchange
-Frame Relay - Cisco
-Frame Relay - IETF Standard
-HDLC - Cisco Proprietary
-LAPB (modulo-128)
-LAPB (modulo-8)
-PPP - Point-to-Point Protocol
-X.25 over LAPB (modulo-128)
-X.25 over LAPB (modulo-8)
Subprotocol If ATM or LAPB is the selected encapsulation method, you must
choose the subprotocols on the link.
ATM subprotocol choices are NLPID and SNAP multi-protocol;
LAPB subprotocol choices are IP and Ethertype multi-protocol
Fractionalized Check if your link is configured for fractionalized operation.
Bandwidth Set to match the bandwidth setting of the link you are analyzing.
