WARNING
To avoid harming the WAN, you must first contact your
carrier for approval before connecting the adapter to the
line.
CAUTION
In accordance with FCC Rules, Part 68.218 (b), you must
notify the telephone company prior to disconnecting the
adapter from the line or turning off the power to the
adapter’s host system. Without this prior notification, the
carrier might temporarily discontinue your T1/PRI service.
Connecting directly to the line with an internal

If your iSPAN-PRI adapter includes the internal CSU option,
you can connect it directly to the line and be up to 6200 feet
(1.8 km) far from your carrier. The line will be in a DS1
