What Is REDSTONE-DS1-MIB?

REDSTONE-DS1-MIB is a private enterprise MIB from Redstone Communications Inc. covering the T1/DS1 physical-layer interfaces on their WAN access platforms. It exposes configuration objects (line mode, line build-out, time-slot mapping, channelization) and physical-layer quality metrics (line attenuation, line length) used to characterize and troubleshoot T1 circuits. Its primary monitoring value is in hardware/line status: detecting degraded signal conditions, misconfigured line build-out, or excessive attenuation that would cause bit errors or circuit outages on the DS1 span. It naturally complements the standard DS1/E1 MIB (RFC 1406/2495-style) conventions, since Redstone's rsDsx1 objects mirror the structure of the IETF DS1 MIB while adding vendor-specific capabilities. It is deployed on Redstone access routers or muxes that terminate leased-line T1 circuits, typically monitored by carriers or enterprises relying on those circuits for WAN connectivity, with the REDSTONE-DS1-MIB download generally sourced from the device vendor's legacy documentation archive.

IPNetwork Monitor allows you to monitor SNMP objects defined in REDSTONE-DS1-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Monitoring Examples

An engineer would poll rsDsx1ConfigTable/rsDsx1ConfigEntry keyed by rsDs1ChannelNumber to check rsDsx1Mode, rsDsx1LineBuildOutType, and rsDsx1TimeSlotMap against the expected circuit provisioning. Rising rsDsx1LineAttenuation or a mismatched rsDsx1LineLength reading relative to the known cable run would point to a physical-layer fault causing errored seconds on the T1. Comparing rsDsx1Capabilities to rsDsx1LineBuildOutCapabilities helps confirm the interface is configured within its supported hardware limits.

What Can Be Monitored

T1/DS1 line configuration and mode
line build-out settings
line attenuation and line length
time-slot channel mapping
DS1 alarm/fault conditions

OIDs

OID symbolic	OID numeric	Type	Access	Description
rsDs1MIB	1.3.6.1.4.1.2773.2.5			The T1 MIB for the Redstone Communications Inc. enterprise.
rsDs1Objects	1.3.6.1.4.1.2773.2.5.1
rsDsx1ConfigTable	1.3.6.1.4.1.2773.2.5.1.1		not-accessible	This table contains entries for DS1/E1 interfaces present in the system.
rsDsx1ConfigEntry	1.3.6.1.4.1.2773.2.5.1.1.1		not-accessible	Each entry describes the characteristics of an DS1/E1 interface.
RST rsDsx1TimeSlotMap	1.3.6.1.4.1.2773.2.5.1.1.1.1	RsTimeSlotMap	read-only	A bitmap representing the timeslots on the DS1/E1 interface that have been allocated for service. For channelized DS1/E1, set bits reflect the union of timeslot allocations across all fractional arrangements operating over this DS1/E1 interface. For unchannelized DS1/E1, all relevant timeslot bits will be set.
I32 rsDsx1Ds1ChannelNumber	1.3.6.1.4.1.2773.2.5.1.1.1.2	Integer32	read-only	This variable represents the channel number of the DS1/E1 on its parent DS3/E3. A value of 0 indicates this DS1/E1 does not have a parent DS3/E3.
I32 rsDsx1Capabilities	1.3.6.1.4.1.2773.2.5.1.1.1.3	Integer32	read-only	A value which indicates the set of capabilities of the DS1/E1 interface. The value is a sum. This sum initially takes the value zero, Then, for each capability, C, in the range 1 through 3, that this interface supports, 2 raised to (C - 1) is added to the sum. For example, an interface which is only E1 capable would have a value of 2 (2^(2-1)). In contrast, an interface which is both T1 and J1 capable would have a value of 5 (2^(1-1) + 2^(3-1)). The values for DS1/E1 interface capabilities are as follows: capability function 1 T1 2 E1 3 J1
INT rsDsx1Mode	1.3.6.1.4.1.2773.2.5.1.1.1.4	INTEGER	read-write	This variable represents the DS1/E1 interface mode. The value of the rsDsx1Capabilities object for the DS1/E1 interface indicates the valid set of values for this object.
I32 rsDsx1LineBuildOutCapabilities	1.3.6.1.4.1.2773.2.5.1.1.1.5	Integer32	read-only	A value which indicates the set of line build out capabilities of the DS1/E1 interface. The value is a sum. This sum initially takes the value zero, Then, for each line build out capability, C, in the range 1 or 2, that this interface supports, 2 raised to (C - 1) is added to the sum. For example, an interface which is only short haul capable would have a value of 2 (2^(2-1)). In contrast, an interface which is both short haul and long haul capable would have a value of 3 (2^(1-1) + 2^(2-1)). The values for DS1/E1 interface line build out capabilities are as follows: line build out capability function 1 short haul 2 long haul
INT rsDsx1LineBuildOutType	1.3.6.1.4.1.2773.2.5.1.1.1.6	INTEGER	read-write	This variable represents the configured line build out type of the DS1/E1 interface. The value of the rsDsx1LineBuildOutCapabilities object for the DS1/E1 interface indicates the valid set of values for this object.
INT rsDsx1LineAttenuation	1.3.6.1.4.1.2773.2.5.1.1.1.7	INTEGER	read-write	This variable represents the configured line attenuation of the DS1/E1 interface. Note that the value of this object only takes effect when the value of the rsDsx1LineBuildOutType for the DS1/E1 interface is set to longHaul(2).
I32 rsDsx1LineLength	1.3.6.1.4.1.2773.2.5.1.1.1.8	Integer32	read-write	This variable represents the length of the DS1/E1 line in meters. Note that the value of this object only takes effect when the value of the rsDsx1LineBuildOutType for the DS1/E1 interface is set to shortHaul(1).
rsDs1Conformance	1.3.6.1.4.1.2773.2.5.4
rsDs1Compliances	1.3.6.1.4.1.2773.2.5.4.1
rsDs1Compliance	1.3.6.1.4.1.2773.2.5.4.1.1			The compliance statement for entities which implement the Redstone DS1/E1 MIB.
rsDs1Groups	1.3.6.1.4.1.2773.2.5.4.2
rsDs1Group	1.3.6.1.4.1.2773.2.5.4.2.1			A collection of objects providing management of DS1/E1 interfaces in a Redstone product.
