5.5.1.5 Hold state
5.5.1.5.1
During the hold state, the DC characteristics of CE providing a line
termination shall not be within the ‘Prohibited’ Region A of Figure 10.
5.5.1.5.2 Momentary breaks during hold state shall not exceed 2.5 ms.
5.5.1.5.3 CE designed to work in parallel with other CE should not have DC
characteristics within the ‘Not Recommended’ Region B of Figure 10.
Compliance with Clause 5.5.1.5 should be checked by using the
method described in Clause 6.7.10.
5.5.1.5.4 Under fault conditions, it is possible for one side of the line to be
grounded close to the CE while it is in the ON-LINE state. The CE
should remain undamaged if this occurs. A suggested test
configuration is shown in Figure 25.
5.5.1.6 Supervision of outgoing calls
STS CE shall remain ON-LINE and not be adversely affected in its
normal operation (before a call is established), if it loses its battery
feed potential for up to 300 ms—
(a) during the predialling hold period;
(b) during interdigital pauses; and
(c) after completion of dialling.
Compliance with Clause 5.5.1.6 should be checked by applying a
300 ms break to the battery feed potential.
5.5.1.7 Dialling digit integrity
5.5.1.7.1
If CE has a keypad or rotary dial—
(a) the decadic signal or DTMF tones it generates shall be
consistent with the ITU–T Rec. E.161 [13] layout chosen;
(b) the sequence of decadic signal or DTMF tones generated
shall correspond to the keys pressed or numbers dialled; and
(c) for decadic dialling, the number of pulses transmitted for a
digit shall correspond to the numerical value of the digit, with
10 pulses being transmitted for the digit '0'.
5.5.1.7.2 Any digit storage facility shall—
(a) correctly store the digits; and
(b) transmit the digits in the same sequence as originally entered,
in accordance with the requirements for decadic or DTMF
signalling as defined in this Standard.
Compliance with Clause 5.5.1.7 should be checked by inspection.
