1X SC4812ET Lite BTS Optimization/ATP Software Release 2.16.1.x

PRELIMINARY

SCCP Cage Configuration and 1X Devices

SC4812ET Lite frames have one SCCP cage which will support up to

four MCC cards and six BBX cards.

MCC Cards

A BTS may be configured with a mix of MCC-8E, MCC-24E, and

MCC-1X cards. Any SCCP cage MCC card slot will support any of the

three MCC types. For 1X capability under R16.0, at least one MCC card

must be an MCC-1X which can be installed in any MCC card slot. In a

BSS operating with Software Release 2.16.0.84.3 and higher, MCC-1X

cards will support IS-95A and B traffic as well as CDMA2000 1X.

When operating with Software Release 2.16.0.5x.x, the MCC-1X cards

do not support IS-95A/B operation. For additional software release

compatibility and capability information, contact the local Motorola

account team.

BBX Cards

Up to six BBX cards of mixed BBX2s and BBX-1Xs can also be

supported. SCCP cage BBX2 card slots 1 through 6 are carrier- and

sector-dependent. As a result, the BBX slots dedicated to the sectors for

one carrier should be populated with the same type of cards. Refer to

Table 1-5 for BBX card slot carrier and sector correlations.

The SCCP cage R1 card slot is dedicated to the redundant BBX. This

slot will support either a BBX2 or a BBX-1X. If a cage has BBX-1X

carriers, the redundant BBX (BBXR) must be a BBX-1X card to provide

1X redundancy.

BBX-1X and BBX2 Interchangeability

In a BSS operating with R16.0 software, BBX-1X cards can be used as

direct replacements for BBX2 cards; however, different types of BBXs

should not be mixed on the same carrier. Therefore, if a BBX2 card is

replaced with a BBX-1X, all remaining BBX2 cards for the carrier

supported by the replaced card must also be replaced with BBX-1X

cards.
