Extension Cables
Extension cables can be ordered for use with the 50-pin FXO, FXS and E&M
Voice APM connectors. They are all straight-through cables (i.e., Pin 1 on the
voice APM side is Pin 1 on the M66 block side of the cable), and they coincide
with the pins on the 50-pin APM connector.
The following table identifies these cables, indicates the voice APM it is used
with, and describes when you might use each:
