What Is C-PRODUCT-CBR-V35-MIB?

C-PRODUCT-CBR-V35-MIB manages V.35 serial interface configuration for channelized/constant-bit-rate (CBR) circuit ports on C-PRODUCT WAN access equipment. It exposes a per-port configuration table covering cable type, transmit/receive clock source and phase, and physical handshaking signal states (RTS, CTS, DCD, DSR). It is strongly hardware-status oriented at the serial line-signal level -- RTS/CTS/DCD/DSR objects directly reflect physical modem-control signal states used to detect a disconnected cable, a DTE/DCE mismatch, or a down serial link, while the clock-source settings affect link synchronization stability. No module_desc was provided, but the naming suggests this is one of a family of C-PRODUCT interface-type-specific MIBs, likely used alongside the standard IF-MIB. It is deployed on WAN access routers/multiplexers using V.35 serial CBR interfaces for leased-line connectivity. Engineers can download the C-PRODUCT-CBR-V35-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in C-PRODUCT-CBR-V35-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.

Supported Devices

Monitoring Examples

An admin reads cbrV35PortConfTable checking cbrV35PortConfRts, cbrV35PortConfCts, cbrV35PortConfDcd, and cbrV35PortConfDsr to determine whether physical handshaking signals are asserted -- an unasserted DCD indicates a disconnected or faulty V.35 cable. cbrV35PortConfCableType and cbrV35PortConfCableID identify which cable variant is attached, and cbrV35PortConfScrClockSource/cbrV35PortConfSctClockSource reveal which clock source is driving the link, useful when diagnosing clocking-related synchronization errors.

What Can Be Monitored

RTS/CTS/DCD/DSR signal states
cable type and cable ID
clock source configuration
transmit clock phase setting

OBJECT-TYPE

OIDs

OID symbolic	OID numeric	Type	Access	Description
cbrV35PortConfig	1.3.6.1.4.1.43.1.12.3.1.1.15.5
cbrV35PortConfTable	1.3.6.1.4.1.43.1.12.3.1.1.15.5.1		not-accessible	This object contains the CBR's V.35 specific port Configuration table. There is one cbrV35PortConfEntry associated for each provisioned CBR port interface within the shelf. This table uses portSlot and portNumber as an index which is defined in the portBaseTable of the C-PRODUCT BASE MIB. This index value uniquely identifies the CBR port interface to which this entry is applicable.
cbrV35PortConfEntry	1.3.6.1.4.1.43.1.12.3.1.1.15.5.1.1		not-accessible	An entry in the CBR specific port Configuration table.
INT cbrV35PortConfCableType	1.3.6.1.4.1.43.1.12.3.1.1.15.5.1.1.1	INTEGER	read-only	This object indicates the type of cable connected to the port. An error is returned if an access is attempted on a physical interface other than a V.35 port interface. The default value is none (1).
INT cbrV35PortConfScrClockSource	1.3.6.1.4.1.43.1.12.3.1.1.15.5.1.1.2	INTEGER	read-write	This object indicates the SCR clock source. This is aplicable for both DCE & DTE cable types. If the cable type is 'none', a get request returns whatever the value currently stored in the managed node for this port and a set request stores the value.
INT cbrV35PortConfTxClockPhase	1.3.6.1.4.1.43.1.12.3.1.1.15.5.1.1.3	INTEGER	read-write	This object indicates the type of Transmit clock phase needed to correct the clock out of phase problem. This is aplicable ONLY when a 'dte' cable is connected to the port. The default value is normal (1).
INT cbrV35PortConfRts	1.3.6.1.4.1.43.1.12.3.1.1.15.5.1.1.4	INTEGER	read-only	This object indicates RTS pin status. Default value is off (1).
INT cbrV35PortConfCts	1.3.6.1.4.1.43.1.12.3.1.1.15.5.1.1.5	INTEGER	read-only	This object indicates CTS pin status. Default value is off (1).
INT cbrV35PortConfDcd	1.3.6.1.4.1.43.1.12.3.1.1.15.5.1.1.6	INTEGER	read-only	This object indicates DCD pin status. Default value is off (1).
INT cbrV35PortConfDsr	1.3.6.1.4.1.43.1.12.3.1.1.15.5.1.1.7	INTEGER	read-only	This object indicates DSR pin status. Default value is off (1).
INT cbrV35PortConfSctClockSource	1.3.6.1.4.1.43.1.12.3.1.1.15.5.1.1.8	INTEGER	read-write	This object indicates the type of SCT clock source. This is aplicable for both 'DCE' & 'DTE' cable types. If no cable is attached then it just reflects the value stored in the database. The default value is internal (2).
INT cbrV35PortConfRxTimingSource	1.3.6.1.4.1.43.1.12.3.1.1.15.5.1.1.9	INTEGER	read-write	This object indicates the Serial interface Recieive Timing Source. The default value is dce-transmit-clock.
INT cbrV35PortConfCableID	1.3.6.1.4.1.43.1.12.3.1.1.15.5.1.1.10	INTEGER	read-only	This object indicates the type of physical interface.
INT cbrV35PortConfLoopBackType	1.3.6.1.4.1.43.1.12.3.1.1.15.5.1.1.11	INTEGER	read-write	This object indicates the type of loopback configured for the specified T1/E1 port interface. Network-line (2) redirects incoming remote traffic back into the network interface at the external edge of the card interface. Network-card (4) regenerates framing information prior to redirecting incoming remote traffic back into the network interface. Local-card (3) redirects local incoming traffic back into the local system. The default value is no-loopback (1).
