NOTES:
1. It may be necessary to cut off the CSU end of the cable and attach a different
connector to match that of the CSU. If possible, this connection should be soldered
because good connections are critical.
2. It is recommended that the CSU be connected to the network interface with a cable
supplied by the CSU manufacturer. If this is not possible or practical, a custom
cable has to be made up. This cable should be made from 22 gauge two pair cable
with each pair individually shielded. It is recommended that the connections on this
cable be soldered wherever possible to ensure good connections. The shielding of
the cable should be connected to ground at the CSU end only to prevent a ground
loop.
