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.
8.This apparatus has been approved for the following facilities:
•Connection to direct exchange lines providing DTMF signaling
•Connection to compatible PBXs providing DTMF signaling
•Operation in the absence of proceed indication, selectable by user
•Call progress monitoring functions
•Data modem functions
•
•
Any other usage will invalidate the approval of the apparatus, if as a result, it then ceases to conform to the standards against which approval was granted.
All apparatus connected to this modem, and thereby connected directly or indirectly to the British Telecom Public Switched Telephone Network, must be approved apparatus as defined in Section 22 of the British Telecommunications Act of 1984.
Although this equipment can use either loop disconnect or DTMF signaling, only the performance of the DTMF signaling is subject to regulatory requirements for correct operation. It is therefore strongly recommended that the equipment is set to use DTMF signaling for access to public or private emergency services. DTMF signaling also provides faster call set up.
The modem may not be used on extension wiring that makes use of plug pins 1 and
6.If in doubt, advice must be obtained from a competent telecommunications engineer.
