Table CLLI

Table CLLI defines both a name and a quantity to a certain MTX trunk assignment. For the Metro application the number of trunks assigned in TRKGRSIZ should be capable of supporting the additional VCHs supported. The minimum number of trunks required is shown in Table 6-2 for various Metro configurations with the maximum number of DRUs.

Table 6-2

Trunk requirement for different Metrocell configurations

Metro Site Type	Minimum Number of Trunks assigned to Table
	CLLI field TRKGRSIZ

Omni site	24

120 Sectored (1 RF Frame)	24

60 Sectored (2 RF Frames)	48

Note: It is a good practice to assign more trunks than is necessary to prevent from having to backtrack through all the Tables to change the number in Table CLLI.

Table ACUALM

A Metrocell has input alarm points hardwired to the ACU. The alarm points for the CE Frame remain the same as per the standard NT800DR Macro Cell Site although their numbering scheme is changed. However the Metro RF Frame alarm points differ. The alarm point configuration for each Metro RF Frame has 23 alarm points to be datafilled in Table ACUALM. The alarm points monitor the:

•TRU/DPA cooling fans

•A and B side DC power filters

•ATC: cavities, DC power, and cooling fan

The alarm points are also assigned for each DRU in the frequency assignment tables (CCHINV, LCRINV, VCHINV) of the Metro Cell Site.

The MTX alarm point numbers for the hardwired Metro RF frame alarm points are listed in Table 6-3 and Table 6-4 for the MTX Table ACUALM.
