DI-206 ISDN Remote Router
•Rx FAE Packets – Frame Alignment Error. The number of packets received that does not end on a byte boundary and the CRC does not match.
•Rx Overrun Packets – The number of packets received that exceed the 1518 octet maximum length imposed on Ethernet packets. Overrun packets are generated by some proprietary software applications.
•Rx MPA Packets – Missed Packet. This is a count of packets intended for the router, but at the time, the router could not receive the packet (usually due to the temporary lack of receive buffers).
•Rx DFR Packets – Deferred Packets. This is a count of incidents where CRS (carrier signal lost) and COL both occur at the same time. These two events happen simultaneously as a result of jabber (produced by faulty networking equipment, usually NIC’s).
ISDN Counter Table
•Tx Packets – The total number of valid packets transmitted by the router since the last reset.
•Tx Bytes – The total number of bytes transmitted by the router.
•Tx Discard Packets – The number of packets dropped by the router.
•Tx Error Packets – The number of invalid packets transmitted by the router. This hardware counter shows the sum of Collisions, Abort and Underrun packets.
•Tx Underrun Packets – Runt packets. This counter shows the number of packets transmitted by the router that are less than the allowed 64 octets minimum length. Underrun packets occur due to jam signals generated by collisions, backpressure, etc.
•Tx Lost CTS Packets – The number of Clear To Send packets that were lost by the router.
•Rx Packets – The total number of packets received by the router.
