D/I MUX III User's Manual
The REN is used to determine the quantity of devices that may be connect to the telephone line and still
have assurance that all of those devices will ring properly when the applicable number is called. In most,
but not all areas, the sum of the RENs of all devices should not exceed five (5). To be certain of the
number of devices that may be connect to a line, as determined by the RENs, the local telephone
company should be contacted for information on the maximum REN for that calling area.

* In some cases connection of this system requires filing an affidavit with the telephone company. When
connecting a system configured without an integral CSU, report the FCC registration number which contains the
equipment code "XD". An external FCC registered CSU is required to connect "XD" category equipment to the
1.544 Mbps public network. The Facility Interface Code is determined from the CSU.
