In Figure 7 an example for base station configuration is sketched. The PEB/F 2091
Version 5.3 is designed to suit to PEB 24911/PEB 24902 (DFE-Q/AFE) in the linecard,
and to the PMB 2727 (Multichannel Burst Mode Controller) in the base station. Several
special features concerning S/G bit control (see "S/G Bit and BAC Bit Operations", page
198) allow flexible and cost effective construction of base station boards without the
need for external circuitry for S/G bit evaluation. Like the S/G bit, the S/G pin can be used
for transmitting a common synchronization pulse to the burst mode controller. Moreover
the undervoltage detection feature (see "Undervoltage Detection", page 92) can be used
to monitor power supply drops on the board.
