5.1.3 Transmitted voltages
Voltages transmitted to a Telecommunications Network from CE, in
any line condition, are not to exceed the limits for
Telecommunications Network Voltages (TNV), as specified in
AS/NZS 60950.1 [3].
Note: AS/NZS 60950.1 [3] specifies applicable safety requirements of CE.
5.1.4 Line-powered CE
The current drawn by CE when connected to a source of—
(a) 100 V d.c.; and
(b) 50 V d.c.
shall not exceed that which would be drawn by 1 MΩ resistor
replacing the CE. This requirement applies 30 seconds after voltage
has been applied.
Note: On some carrier network equipment, CSS and other CE, the nominal
OFF-LINE feedbridge voltage may be as low as 24 V.
Compliance with Clause 5.1.4 should be checked by using the test
circuit of Figure 2 with the CE in the OFF-LINE condition with the
battery voltage set as above.
5.1.5 Line connection
CE should terminate on and be supplied with—
(a) an insulation displacement system frame, internal or external
to the CE;
(b) a cable complying with AS/CA S008 [6] and which is able to
be terminated on an insulation displacement system frame;
(c) a socket on the CE complying with AS/CA S008 [6]; or
(d) a plug on the end of a line cord, where both the plug and
cord comply with the requirements of AS/CA S008 [6] and the
plug is one of the following types:
(i) Plug Type 605;
(ii) Plug Type 606;
(iii) ANSI/TIA-968-A-2002 [9] (six-position); or
(iv) ANSI/TIA-968-A-2002 [9] (eight-position).
Note 1: The PSTN is normally terminated on one of the following connectors:
(i) Insulation displacement or solder termination MDF; or
(ii) Compliant sockets including:
a. Socket Type 610.
