Using a standard, straight through eight conductor data cable or straight through eight

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.
3. T1/E1 is not supported on the OfficeServ 7100 system.
