SCCP Cage Configuration and

the 1X Devices

SC4812ET Lite frames have one SCCP cage which will support up to 4

MCC cards and 6 BBX cards.

MCC Cards

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

MCC–1X cards. Any 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.

BBX Cards

Up to 6 BBX cards of mixed BBX2s and BBX–1Xs can also be

supported. BBX 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 BBX–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 support.
