If FR2K option is installed, it will be possible carrying tests in order to install and 
check Frame Relay services over WAN (Wide Area Network) links. The device is 
able to emulate a CPE (Customer Premise Equipment) device, in order to 
determinate the availability of Frame Relay service before installing the end user 
terminal (e.g. a router). 

The protocol is available over G.703, G.704, V.11-X.21, V.35 and V.36 interfaces. 

The test equipment shows in the Smart Status page regarding Frame Relay, all the 
information about traffic, quality of the service (QoS), controlling protocol LMI. 

In the first screen page the device displays: 

► 

Number of transmitted and received frames 

► 

Counters of frames with FECN (Forward Explicit Congestion Notification) bit  

► 

Counters of frames with BECN (Backward Explicit Congestion Notification) bit 

► 

Counters of frames with DE (Discard Eligibility) bit 

► 

Number of frames rejected because of errors over DLCI, heading or packet’s 
fragmentation 

► 

Number of frames with unexpected DLCI and unexpected DLCI values 

If LMI protocol has been activated, a second status page will be available with 
statistical information about DLCI. The following data is displayed: 

► 

Number of transmitted and received LMI frames 

► 

Number of wrong LMI frames 

► 

Status of DLCI selected 

► 

List of all PVCs configured over the link (DLCI and relative status) 

In presence of LMI activity, that is the network answers to the queries, the device 
displays a specific icon on the top of the screen. 

Goes to page 4 and 5.
