OID (numeric): 1.3.6.1.4.1.930.2.2.2.5.1.1.2

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-only

Description: This field indicates the operational external clock source. The following value is read-only: 0 = Local Oscillator, 1..N = ATM port id for external clock source. This object only applies to ATM MDA modules with SM, MM, or UTP media types.

What is atmCardOperExtClockSource?

Indicates the operational external clock source for an ATM MDA module with SM, MM, or UTP media; a value of 0 means the local oscillator is used, while a value from 1 to N identifies the ATM port supplying the external clock.
