This delay serves two purposes:
It ensures that the answer supervision signal is valid and not a secondary delay-dial or
●
wink-start signal.
It ignores momentary off-hook signals resulting from connections made off-network
●
through certain No. 5 Crossbar CCSA switches as the connection is being established.
Therefore, calls aren't dropped inappropriately.

Usage
Enter e&m for 6-wire connections that pair 2 signaling wires with 4 voice
wires. You'll use e&m in the vast majority of systems in the U.S.
Enter simplex for 4-wire connections that do not use an additional
signaling pair. This configuration is very rare in the U.S.
