Strata CTX28 Overview

System Interface Options
Circuit Cards
Note See the “CTX28 Functional Block Diagram” on page 7 to see how the circuit cards and
interface connectors can be used for connecting stations and peripherals.
Reserve Power
One or two HPFB-6 optional units can be added to the CTX28 to provide reserve power. The
amount of reserve power time depends on the hardware (see
Table 4). The table below is an
estimate of battery backup time based on the premise that the HPFB-6 unit(s) are fully changed at
the time of AC power failure. This estimated backup time is based on normal call traffic, the time
estimates will be reduced by as much as half with extreme heavy traffic volumes.
Note The CTX28 should be plugged into AC power and the DC power switch should be turned
On when installing the HPFU-6. The HPFU-6 will not start to operate if AC power is not
available during the initial installation.
