Model No. Running Head PM-IOR Card User Screens and Settings PM-IOR Card
OSS
The Out of Synchronization Seconds (OSS) field indicates the number of seconds that the
HSU BERT has been out of synchronization. This is an information-only field; it is not
user-configurable.
BER
The Bit Error Rate (BER) field indicates the rate at which errors are being logged. The system
calculates BER by dividing the number of bit errors (BE) by the total number of bits
transmitted during the test. This is an information-only field; it is not user-configurable.
ELAP
The Elapsed time (ELAP) setting indicates the running tally of the total number of seconds
during the test. This is an information-only field; it is not user-configurable.
RTS
The Request To Send (RTS) field indicates the current status of the RTS control lead. The two
values that can be displayed are on and off. This is an information-only field; it is not
user-configurable.
DTR
The Data Terminal Ready (DTR) field indicates the current status of the DTR control lead.
The two values that can be displayed are on and off. This is an information-only field; it is not
user-configurable.
The DTR field will always indicate on for the HSU 35 Card (Revision A and earlier), but it
will toggle between off and on all other HSU Cards.
LB ST
The Loopback State (LB ST) field indicates whether there are any remotely-initiated
loopbacks currently active on the HSU port. This field displays both latching and non-latching
loopbacks initiated from a remote device via in-band loop-up codes. In addition to none, the
six messages that can be displayed in that field are l-ocu, l-dsu and l-csu for latching
loopbacks, and ocu, dsu and csu for non-latching loopbacks. This is an information-only field;
it is not user-configurable.
