Notes:
1. The RS-232 loopback cables are asymmetrical and are labeled "Internal" on one end and
"External" on the other end. The configured clock modes of each port must match the
corresponding end of the loopback cable.
2. The V.35 loopback cables are symmetrical and may be connected either way round. One port
of the pair should be configured for internal (Int) clock and the other to use the (Ext) clock
mode.
