Chapter 1 Overview
Functional Description
The frame format and disable controls are coupled between outputs 1 and 4 and
between outputs 2 and 3. For non-1PPS signals, these output pairs must have the
same signal type since they share the same framer. Only outputs 1 and 2 can be
configured for the 1PPS signal.
If output 4 is disabled, then output 1 will be disabled if it is not configured for 1PPS.
Outputs 3 and 2 have a similar coupling.
For example, if output 1 is configured for 1PPS, then output 4 can be configured for
any signal type, except 1PPS. If output 1 is configured for E1, then output 4 must be
configured as an E1 with the same frame format.
Table 1-1 and Table 1-2 show the supported combinations of output settings.
