This RTB informs the changes made to the G4 (SiG4) unit software and corrections to the
Schmidt3 ISDN Unit service manual.

CHANGES MADE TO THE DEFAULT SETTINGS

1.
The following changes have been made from the first production of August.

Bit Switch 13: D channel layer 3 (Attachment IE in S: SETUP)

FUNCTION COMMENTS

0:

Condition for fallback from G4 to
G3

0:

Refer to the CPS code setting

1:

7

Fallback in response to any

CPS code

Fallback occurs when a CPS code is the
same as the CPS code settings specified by
G4 internal switches 17, 18, 1A, 1B, and 1C.
If you wish to enable fallback when any CPS
code is detected, set this bit to “1.”
This switch is effective in coping with fallback
problems where the CPS code does not match
those specified in the ITU-T recommendation.

The new default setting is “1.”

Communication Switch 07
No FUNCTION COMMENTS

0:

Fallback from G4 to G3 reflected
in programmed Quick/Speed dials

3

0:

Fallback enabled (Default)

1:

Always start with G4

If a communication falls back from G4 to
G3, the machine will always start transmission
with G3 from the next communication.
1: The machine will always start to transmit
with G4.

The new default setting is “1.”

The default settings have been changed to cope with fallback problems where CPS codes
do not match those specified in the IT U-T recommendations. If you are installing machines
that were manufactured earlier than August, it is recommended to change the settings as
explained above to avoid communication problems.

NOTE:

PCB part numbers: H5476170G (Europe/Asia models), H5476180F (USA model)

2. NEW SWITCH ADDED TO THE G4 UNIT

The following changes have been made from the first production of August.

G4 Internal Bit Switch 13
No FUNCTION COMMENTS

1:

Information transfer capability
shift down to retry transmission

0:

Shiftdown procedure disabled

(Default)

1:

Shiftdown and retry the call

1

The mac hine changes the ISD N G3
information transfer capability informed in the
[SETUP] signal to “Speech” from “3.1 kHz
audio” or to “3.1 kHz audio” from “Speech”
automatically and retries the transmission.
The information transfer capability used in the
first try is determined by the setting of G4
internal bit switch 14 bit 0.
This switch is effective with some types of
exchangers and T/As where they only accept
calls with information transfer capability
“Speech.”

G4 Internal Bit Switch 14
No FUNCTION COMMENTS

ISDN G3 information transfer
capability

0:

3.1 kHz audio

1:

0

Speech

In tx mode, this determines the information
transfer capability informed in the [SETUP]
message.
In rx mode, this determines the information
transfer capability that the machine can use to
receive a call.
Set this bit to 1 if the ISDN does not support

3.1 kHz audio.
