qbTimingPortImpedanceMode
Module: QB-TIMING-MIB
OID (symbolic): QB-TIMING-MIB::qbTimingPortImpedanceMode
OID (numeric): 1.3.6.1.4.1.4323.2.11.1.1.8.1.7
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: The object is used to set the impendance in ohms. Note: this value is applicable only for E1 ports.
What is qbTimingPortImpedanceMode?
This read-write object sets the port's line impedance, in ohms, to either 75 or 120, defaulting to 120. The setting applies only to ports configured in E1 format, since DS1 ports use a fixed impedance and don't expose this setting. For example, an admin connecting an E1 BITS source over unbalanced coaxial cable would set qbTimingPortImpedanceMode to 75 rather than leaving the default 120-ohm balanced setting.
