Option Description
Activate the CSU This option depends on whether the connection between
the adapter and the T1 line requires a CSU:
• Select Activate the CSU to activate a CSU between
the network and the adapter. The CSU is included on
the
iSPAN-PRI adapter. However, to activate the
CSU you must purchase the CSU option. (An external
CSU is not required).
• Deselect Activate the CSU to deactivate a CSU
between the network and the adapter.
The CSU facility is protected by a password. You must
enter this password when selecting ‘Activate the CSU’
for the first time. For password instructions, refer to the
Read Me First information provided in your adapter
package.
Network Line
Build Out
The Network line build out compensates for the signal
attenuation due to the length of the cable between the
adapter and the switch.
Four values are available (expressed in dB):
• 0
• 7.5
• 15
• 22.5.
Select the value indicated by your Telco. If this
information is not available, use 0 dB.
