Digital DS3/E3/HSSI 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.
