Module: AC-SYSTEM-MIB

OID (symbolic): AC-SYSTEM-MIB::acSysTDMClockNetRefSpeed

OID (numeric): 1.3.6.1.4.1.5003.9.10.10.1.2.1.5

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: Determines the NetRef frequency (for both generation and synchronization). 0 = 8 kHz 1 = 1.544 MHz 2 = 2.048 MHz. Access: Online. AC INI-Param: TDMBUSNETREFSPEED

What is acSysTDMClockNetRefSpeed?

This OID sets the NetRef frequency output for clock generation and synchronization: 0 (8 kHz), 1 (1.544 MHz), or 2 (2.048 MHz). Engineers choose the frequency based on the external equipment they're synchronizing with—8 kHz for voice signals, or higher rates for T1/E1 line synchronization. Selecting 2 outputs a 2.048 MHz reference signal compatible with E1 telecom standards.
