Datafilling a Metro Cell Site

Datafill Overview

This section outlines the differences which you should consider when datafilling a Metro site. It makes no attempt at dealing with the entire datafill procedure and assumes that you are familiar with the MTX Cell Site Datafill Procedures. Please refer to NTP 411-2131-461 ICP Datafill Guide for information concerning the entire Cell Site Table Datafill.

A Metro Cell site looks for all intensive purposes like any other ICP/ICRM cell site to the MTX. It uses all the same tables, loads, and parameters as do the previous ICP/ICRM methods. The outstanding difference, which is apparent, is that more Trunks and DSPMs will be required to service the additional radios that the Metro RF frame is equipped with. The following datafill tables will be addressed in the view of differences to keep in mind when datafilling a Metro Cell Site:

Table

Metro differences

 

 

CLLI

More trunks should be assigned as each RF frame can be

 

equipped with 8 more radios than a standard macrocell frame.

 

 

ACUALM

PA Fan Alarms are laid out differently with the new RF frame.

 

 

CCHINV

The RF frame location of the DRU should be correctly identified

 

in relation to the ICRM P-side card port number.

 

 

LCRINV

The RF frame location of the DRU should be correctly identified

 

in relation to the ICRM P-side card port number.

 

 

VCHINV

The RF frame location of the DRU should be correctly identified

 

in relation to the ICRM P-side card port number.
