This equipment is required to test a CTS 710 with any one of the optional
Optical/Electrical Plug-in Interface Modules installed; otherwise, it is not
required.
Loop-Back Connection
The incoming inspection test requires an external loop-back
connection from the TRANSMIT/OUT output to the RECEIVE/IN
input. For the SONET rate electrical loop-back, you can use the 75 W
BNC coaxial cable provided as a standard accessory to the CTS 710.
If the Add/Drop/Test Option is installed, you can use the 75 W
coaxial cable for checking DS3 operation, and will need to use a
bantam cable (a standard accessory with the Add/Drop/Test Option)
to check DS1 operation. If one of the Electrical/Optical Plug-in
Interface Modules is installed in your CTS 710, you also need a short
optical cable that is compatible with the optical connectors on your
instrument. Optical cables are not included as standard accessories to
the CTS 710.
