e3TransmitClockSource

Module: ACMIB

OID (symbolic): ACMIB::e3TransmitClockSource

OID (numeric): 1.3.6.1.4.1.1751.2.18.2.11.1.5

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: The source of Tranmit Clock. 'loopTiming' indicates that the recovered re- ceive clock is used as the transmit clock. 'localTiming' indicates that a local clock source is used. 'adaptiveTiming' indicates that the adaptive clocking mechanism is used.

What is e3TransmitClockSource?

This OID selects where the E3 port obtains its transmit clock: from recovered receive clock (loopTiming), a local oscillator (localTiming), or an adaptive mechanism that adjusts timing based on received signals. Network engineers must choose the correct source based on whether your equipment is the master timing reference or recovering clock from the carrier network. For example, if your device connects to a public E3 service, you would typically set this to 'loopTiming' to stay synchronized with the carrier's incoming signal.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.1751.2.18.2.11.1.5
snmpwalk -v2c -c public <target> ACMIB::e3TransmitClockSource

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.1751.2.18.2.11.1.5.1
snmpget -v2c -c public <target> ACMIB::e3TransmitClockSource.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.1751.2.18.2.11.1.5.1 i <value>
