Near End Group – The DS1 Current Table
Objects (dsx1CurrentEntry)
The following DS1 current table objects are provided
for the network interface only. Objects in the table that are
not listed are not supported and will return an error status
if access is attempted.
•
dsx1CurrentIndex – The index that identifies the E1
interface.
•
dsx1CurrentESs – Errored Seconds for the current
interval.
•
dsx1Current SESs – Severely Errored Seconds for
the current interval.
•
dsx1CurrentUASs – Unavailable Seconds for the
current interval.
•
dsx1CurrentBESs – Bursty Errored Seconds for the
current interval.
Near End Group – The DS1 Interval Table
Objects (dsx1IntervalEntry)
The following DS1 interval table objects are provided
for the network interface only. Objects in the table that are
not listed are not supported and will return an error status
if access is attempted.
•
dsx1IntervalIndex – The index that identifies the E1
interface.
•
dsx1IntervalNumber – The interval number
(1 to 96).
•
dsx1IntervalESs – Errored Seconds for the interval.
•
dsx1Interval SESs – Severely Errored Seconds for
the interval.
•
dsx1IntervalUASs – Unavailable Seconds for the
interval.
•
dsx1Interval BESs – Bursty Errored Seconds for
the interval.
Near End Group – The DS1 Total Table Objects
(dsx1TotalEntry)
The following DS1 total table objects are provided for
the network interface only. Objects in the table that are not
listed are not supported and will return an error status if
access is attempted.
•
dsx1TotalIndex – The index that identifies the E1
interface.
•
dsx1TotalESs – The 24-hour total Errored Seconds.
•
dsx1Total SESs – The 24-hour total Severely
Errored Seconds.
•
dsx1TotalUASs – The 24-hour total Unavailable
Seconds.
•
dsx1TotalBESs – The 24-hour total Bursty Errored
Seconds.
Far End Group, DS1/E1 MIB
The DS1 Far End Group consists of the following three
tables:
•
DS1 Far End Current
•
DS1 Far End Interval
•
DS1 Far End Total
These tables are not supported for either the network or
G.703 DTE interface.
The DS1 Fractional Group, DS1/E1 MIB
The DS1 Fractional group consists of the DS1
fractional table. This table (dsx1FracTable) is fully
supported by the 336x NTUs and allows channel (time
slots) to be mapped between the E1 interfaces and data
ports. If an invalid channel map (e.g., two interfaces
mapped to a single time slot, one interface mapped to two
E1s, etc.) is received, an error is returned to the SNMP
manager. The E1 NTU validates all channel
configurations before applying them.
Operational Note: The fractional E1 group only allows
specification of an entire interface to a particular time slot
on another interface (i.e., a time slot on one interface
cannot be mapped to a time slot on another interface).
This prevents complete mapping of time slots on the
G.703 DTE interface to time slots on the network
interface. For mapping time slots between the network
and G.703 DTE interfaces, the following convention is
used: Time slots on the E1 interface that are mapped to
another E1 interface (i.e., not a data port) are connected in
ascending order. For example, if the fractional table for
the network interface maps time-slots 1, 3 and 5 to the
G.703 DTE interface and the G.703 DTE interface maps
time-slots 10, 11 and 15 to the network, the following
time slots are connected: N1 to D10, N3 to D11, and N5
to D15.
