for connection to its network. It indicates no endorsement of the product by
Telecom, nor does it provide any sort of warranty. Above all, it provides no
assurance that any item will work correctly in all respects with another item
of Telepermitted equipment of a different make or model, nor does it imply
that any product is compatible with all of Telecom’s network services.
Some parameters required for compliance with Telecom’s Telepermit
requirements are dependent on the equipment (PC) associated with this
device. The associated equipment shall be set to operate within the following
limits for compliance with Telecom’s Specification:
vThere shall be no more than 10 call attempts to the same number within
any 30 minute period for any single manual call initiation, and
vThe equipment shall go offline for a period of not less than 30 seconds
between the end of one call attempt and the beginning of the next attempt.
Where automatic calls are made to different numbers, the equipment shall
go offline for a period of not less than 5 seconds between the end of one
call attempt and the beginning of the next attempt.
vWhen used in the automatic answer mode, the equipment shall be set to
answer within 3 to 30 seconds of the receipt of ringing.
This equipment shall not be set-up to make automatic calls to the Telecom 111
emergency service.
For the modem with approval number PTC 211/99/255
Not all phones connected to the phone port will respond to incoming ringing.
Do not report this as a fault unless the same phone will not respond to
ringing when connected to a standard phone socket.
This equipment shall not be set up to make automatic calls to the Telecom 111
Emergency Services.
The grant of a Telepermit for a device in no way indicates Telecomacceptance
of responsibility for the correct operation of that device under all operating
conditions. In particular, higher speeds at which this modem is capable of
operating depend on a specific network implementation which is only one of
many ways of delivering high quality voice telephony to customers. Failure to
operate should not be reported as a fault to Telecom.
In addition to satisfactory line conditions a modem can only work properly if:
it is compatible with the modem at the other end of the call and,
the application using the modem is compatible with the application at the
other end of the call - e.g. accessing the Internet requires suitable software
in addition to a modem.
