U.K. BABT Users Notice

	(SupraExpress 56i Pro Global Modem - Desktop Products Only)
	The modem is intended for only use in the Compaq Internet PC. For the purposes of
	BABT approval, the modem is classified as a host-independent product.
Telephone	The modem is suitable for connection to the Public Switched Telephone Network
Network	(PSTN) direct exchange lines and relevant branch systems (PBXs).
Connection	A ringer equivalent number (REN) is a value given to all apparatus to be connected to

	the PSTN. Its value can be taken and used to calculate the maximum number of
	equipment items that can be connected in parallel without impairing the performance
	of the standard bell circuit.
	1.	REN = 3/n where n is the maximum number of units that may be used in parallel.
	2.	The maximum REN of a line is 4; therefore, the total REN of all apparatus
		connected to the line (obtained by summing the individual REN values) should
		not exceed 4. This value includes any BT provided instrument, each of which is
		assumed to have REN value of 1.0 unless otherwise stated. Exceeding the REN
		value of 4 may cause your telephone(s) to ring weakly or not ring at all.
	3.	Only one modem should be connected to a telephone line. Connecting a modem
		in parallel with one or more telephone instruments is not allowed.
	4.	The REN for this piece of equipment is 0.8.
	5.	The exchange should provide facilities for either loop disconnect (pulse) dialing
		or multifrequency (tone) dialing. The modem can be configured to operate with
		either system.
	6.	During dialing, this apparatus may tinkle the bells of other telephones using the
		same line. This is not a fault, and we advise you not to call the Fault Repair
		Service.
	7.	The modem specified in this guide is for the Compaq Internet PC.
