cgmClkDist MIB Description

The following table describes the elements of the cgmClkDist MIB branch (OID:.1.3.6.1.4.1.3656.8152.1.4).

Table 5-9 cgmClkDist Objects

OID	MIB Object	Description		Access
.1.4.10	cgmClkDistMode	The clock distribution mode of the module.		r/w
		There are four main modes a module can be
		operated in:
		z	Distributed Mode (0)
			For each clock domain (CLK1/2/3), the
			module selects a payload card in the shelf
			and replicates it to the other payload cards.
			The selection can be done manually or
			automatically.
			Not applicable for PMC-CGM.
		z	Extension Mode (1)
			The module receives CLK1/2 from the main
			shelf and distributes them to the local
			payloads. Reference clocks (CLK3) can be
			routed to the main shelf.
			Not applicable for PMC-CGM.
		z	Buffer Mode (2)
			The module receives CLK1/2/3 from the
			main shelf and distributes them to the local
			payloads.
			Not applicable for PMC-CGM.
		z	Centralized Mode (3)
			The module generates the T0 clocks based
			on internal or external references. In
			centralized mode there may be up to two
			shelves connected, operating in either
			extension or distribution mode.
		z Extended Centralized Mode (4)
			Like centralized mode, except that CLK3 is
			routed to the main shelf via the front-panel
			connector (i.e. REF A/B can not be selected
			as input).
			Not applicable for PMC-CGM.
		Default value is centralized mode (3).
.1.4.11	cgmExtChConnection	In centralized mode, selects the properties of the		r/w
		connections to extension chassis 2 and 3 (not
		connected, extended mode or buffered mode):
		Single Chassis (0)
		Chassis 2 in extension mode (1)
		Chassis 3 in extension mode (3)
		Chassis 2 and 3 in extension mode (5)
		Default value is (0).
