RIM
The total number of Request Initialization Mode (RIM) frames received from or 
transmitted to an adjacent SDLC link station since link station startup, expressed 
as a rate (RIM frames/second). 
DISC
The total number of Disconnect (DISC) requests received from or transmitted to 
an adjacent SDLC link station since link station startup, expressed as a rate 
(DISCs/second). 
UA
The total number of Unnumbered Acknowledgment (UA) requests received from 
or transmitted to an adjacent SDLC link station since link station startup, 
expressed as a rate (requests/second). 
DM
The total number of Disconnect Mode (DM) requests received from or transmitted 
to an adjacent SDLC link station since link station startup, expressed as a rate 
(requests/second). 
SNRM
The total number of Set Normal Response Mode (SNRM/SNRME) requests 
received from or transmitted to an adjacent SDLC link station since link station 
startup, expressed as a rate (requests/second). 
Octets
The total octets received from or transmitted to an adjacent SDLC link station 
since link station startup, expressed as a rate (octets/second). This includes the 
address, control, and information Þeld of I-frames only.
Retransmits
In the Rx Statistics window, this is the total number of I-frames retransmitted by 
the remote link station because the N(s) received from that link station indicated 
that one or more I-frames sent by or to that station were lost. 
In the Tx Statistics window, this is the total number of I-frames retransmitted to a 
remote link station because the N(r) received from that link station indicated that 
one or more I-frames sent by or to that station were lost.
This event causes the Þrst missing I-frame of a window and all the subsequent 
I-frames to be retransmitted. This value is expressed as a rate 
(retransmits/second).
