Day Count Registers
The day count registers count the number of events that
have occurred in the previous 24 hour period. There are
five separate day count registers. They are:
ESDCR (2D)
UASDCR (2E) counts Unavailable Seconds (UAS)
BESDCR (2F) counts Bursty Errored Seconds (BES)
SESDCR (30) counts Severely Errored Seconds
(SES)
CSLFDCR (31) counts Controlled Slip Seconds (CSS)
and Loss Of Frame Counts (LOFC)
counts Errored Seconds (ES)
Each of these current interval registers are 16 bits in
length. Please see “54016 Definitions” for definitions of
ES, UAS, BES, SES, CSS, and LOFC.
VITR: Valid Interval Total Register (32)
.
An 8–bit
register that counts the number of 15 minute intervals
since the last reset. Hence, it has a maximum count of
96.
RMSR: Request Message Status Register
(33)
.
An 8–bit register that indicates which (if any) re-
quest maintenance message has been received. If a re-
quest maintenance message is received, the INT pin
will be asserted (transitions low). The RMSR will be
cleared when read. This indicates to an external con-
troller that a request has been received and is being pro-
cessed. The INT pin will return high as soon as the
RMSR is accessed. There are currently 15 request
messages defined.

CR: Control Register (34)
.
An 8–bit register that
selects whether the DS2282 will respond to address A
(or Z) or address B (or Y). The default is for the DS2282
to respond only to address A (or Z). The user can set the
DS2282 to respond address B (or Y) by setting the AD
bit to a one. In addition, CR allows the user to send an all
one’s sequence FFh or LAPD idel code 7Eh.

54016 DEFINITIONS
Errored Seconds (ES)
: A one–second period with ei-
ther:
a. one or more CRC–6 error events or
b. one or more OOF events or
c. one or more controlled slips.
Severely Errored Seconds (SES)
: A one–second peri-
od with either:
a. 320 or more CRC–6 error events or
b. one or more OOF events.
Unavailable Seconds (UAS)
: A one–second period in
which an unavailable signal state is present. In counting
UAS, the initial period of 10 consecutive SES’s is in-
cluded in the count whereas the final 10 seconds of 10
consecutive non–SES’s which removes the unavailable
signal state is not included in the count. During UAS’s,
neither ES, or SES, or BES, are counted. Refer to
“Monitor Registers” for a more detailed description of
UAS.
Unavailable Signal State
: An unavailable signal state
is declared when 10 consecutive SESs have been re-
ceived. An unavailable signal state is considered
cleared when 10 consecutive non–SES events have oc-
curred.
Controlled Slip Seconds (CSS
): A one–second period
with one or more controlled slips. A controlled slip is the
deletion or replication of a DS1 frame. Indications of
controlled slips are input to the DS2282 via the SLIP pin.
If indications of controlled slips are not available, the
SLIP pin should be tied low.
