Form 70-Cd-IP - ISDN Interface Specifications Program
70-Cd-IP S/T TYP
111
Cd = 01-04, IP = 01-03
System default
General:
To assign the ISDN interface to “S” interface or “T” interface.
Description:
Cd= 01 is to assign the “S” or “T” interface for the ISDN port on G2-SIU card.
0= “S” interface. It can connect two ISDN devices. Use Program 43-CN to set the Device Station
Number (Station Type is 9).
1= “T” interface. It can be connected to “NT” interface of ISDN line.
Cd= 02 is for the test purposes only.
0= Loopback disabled
1= Loopback enabled
Cd= 03 is for connection method.
0= Point to Point(recommend ‘0’ for internal ISDN S interface use if only one ISDN device connected)
1= Point to Multi-point (Default)
2= Point to Multi-point and ignore the unknown MSN or DDI number (not assigned in mode 72)
 This application is normally for other ISDN device (e.g. ISDN TA, ISDN video conference, ISDN card, …)
that is connected to NT1 with TD-1648i/TDS-600 together.
Cd= 04 is for ISDN PLL (Phase Loop Lock)
0= Auto detect
1= Lock this ISDN line for PLL. Signal.
The following table is the Cross Reference Table for physical position of ISDN interface and
programming position.
Cd
Cd=01 Cd=02 Cd=03 Cd=04
IP=01 1st interface 1st interface 1st interface 1st interface
IP=02 2nd interface 2nd interface 2nd interface 2nd interface
IP
IP=03 3rd interface 3rd interface 3rd interface 3rd interface
Example:
70-01-IP S/T TYP
110
It sets the 1st and 2nd ISDN interface to “T” interface and 3rd interface to “S” interface.
The user can program the station number in program mode 43, port 61~68.
