Paradyne 316x RS-232-like MIB RFC, Near End Group ± The DS1 Total Table Objects dsx1TotalEntry

Near End Group ± The DS1 Total Table Objects (dsx1TotalEntry)

The following DS1 total table objects are provided for the Network T1 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 T1 interface.

•dsx1TotalESs ± The 24-hour total Errored Seconds.

•dsx1Total SESs ± The 24-hour total Severely Errored Seconds.

•dsx1TotalUASs ± The 24-hour total Unavailable Seconds.

•dsx1TotalCSSs ± The 24-hour total Controlled Slip 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 DTE Drop/Insert T1 interfaces.

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 T1 DSU/CSU and allows channel (time slots) to be mapped between the T1 interface and data ports. If an invalid channel map (e.g. two interfaces mapped to a single time slot, one interface mapped to two T1s, etc.) is received an error will be returned to the SNMP manager. The T1 DSU/CSU validates all channel configurations before applying them.

Operational Note: The fractional T1 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 DTE Drop/Insert T1 interface to time slots on the network T1 interface. For mapping time slots between the network and DTE T1 interfaces the following convention will be used. Time slots on the T1 interface that are mapped to another T1 interface (i.e., not a data port) will be connected in ascending order. For example, if the fractional table for the network T1 interface maps time slots 1, 3 and 5 to the DTE T1 interface and the DTE T1 interface maps time slots 10, 11 and 15 to the network the following time slots will be connected: N1 ± D10,

N3 ± D11, and N5 to D15.

RS-232-like MIB (RFC 1317)

The ªrs232º object defined by RFC 1317 is supported for all of the synchronous DCE data ports, the MODEM port, and the COM port. The RS-232-like MIB consists of one object and five tables, as follows:

•Number of RS-232-like ports

•The General Port Table

•The Asynchronous Port Table

•The Synchronous Port Table

•The Input Signal Table

•The Output Signal Table

The Asynchronous Port Table is not supported by the DSU/CSU for the synchronous DCE data ports. The Input Signal and Output Signal Tables are not supported for the MODEM and COM ports. The following sections provide clarification for objects contained in the RS-232-like MIB when it is not clear how the object definition in MIB is related to the DSU/CSU.
