Note that some methods of connection to the network or circuit are the responsibility of
the public telecommunications operator or a person authorised by that operator.
If any other apparatus, including cable or wiring, is to be connected to any speech band
circuit, then all that other apparatus shall comply with the following:
(1)
The overall transmission characteristics of all that other apparatus shall be such as
to introduce no material effect upon the electrical conditions presented to one
another by the apparatus and the speech band circuit.
(2)
All other apparatus shall comprise only:
(i)
Apparatus approved (see note) for the purpose of connection between the
T805 and the speech band circuit;
(ii)
Cable or wiring complying with a code of practice for the installation of
equipment covered by Section 9 of BS6328 or such other requirements as
may be applicable.
Figure 7.3 shows the levels that should be presented to the Telecom lines if the system is
correctly aligned and a balanced test tone of 1kHz at -10dBm is injected into input 1 of
the TSGM.
Note:
To key the appropriate transmitter in the system:
either
make the ICCS input of the corresponding AIM active;
or
sum a 2970Hz key tone at -23dBm into the TSGM's audio input.
No adjustment of the levels into or out of the ASP card should be required if they are set
using the methods described in either Sections 7 or 8 (all input and output levels are set
for 600
Ω
terminations).
