gdcDsuChannelTransmitClockSource

Module: GDC-DSU-MGMT-MIB

OID (symbolic): GDC-DSU-MGMT-MIB::gdcDsuChannelTransmitClockSource

OID (numeric): 1.3.6.1.4.1.498.8.5.2.1.21

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: This object operates in conjunction with gdcDsx1TransmitClockSource in gdcdsx1.mib. If gdcDsx1TransmitClockSource is channel(4), then this object defines whether or not the channel's customer business equipment is providing timing with ext Tx Clk to the network's transmit interface.

The value disabled(1) indicates the channel's customer business equipment is not providing timing for the transmit network interface.

The value enabled(1) indicates the channel's customer business equipment is providing timing for the transmit network interface.

What is gdcDsuChannelTransmitClockSource?

When the DSU's overall transmit clock source is set to derive timing from a channel, this object controls whether this specific channel's customer business equipment supplies that timing via its external transmit clock; enabled(1) means it does.

Examples
