INFO1 signal resend 0: Resend

1: No resend

In most countries (including Europe), this should be disabled.

This should be kept at 5 s (both bits at 0) for normal operation. However, you may have to change this during PTT approval tests.

Set this bit to 1 for French PTT approval tests.

0: Some DSUs may not reply to the INFO1 signal with INFO2, if there is noise in the INFO1 signal accidentally. Try changing this bit to 0, to resend INFO1 before the machine displays “CHECK INTERFACE”.

This is normally kept at 0. However, set it to 1 for British PTT approval tests.

This is normally fixed at 0. However, some networks such as the Northern Telecom ISDN may require this bit to be set at 1 (see below). In this case, you may have to change the values of bits 2 to 7.

ISDN) exchanger. Store the lowest bit of the TEI at bit 7 and the highest bit of the TEI at bit 2. Example: If the static TEI is 011000, set bits 3 and 4 to 1 and bits 2, 5, 6, and 7 to 0.

Bit switch 12 is not used. Do not change an y of the factory settings.

Not used Do not change the factory settings.

Normally, this bit should be at 0, because most networks add the calling ID to the SETUP signal to the receiver. However, some networks may require the machine to add this ID. Only in this case should this bit be at 1.

This bit determines whether Lower Layer Capabilities are informed in the [SETUP] signal or not. Keep this bit at 0 in most cases.

This bit determines whether Higher Layer Capabilities are informed in the [SETUP] signal or not. Keep this bit at 0 in most cases.
