MSN Address is useful to the following Features for decoding the single ISDN Device from ISDN Devices on the same S-Interface
(bus),
(1) Intercom Call to ISDN Station
(2) DID Call to ISDN Station
(3) DISA Call to ISDN Station
On the other features, MSN Addressing does not effect ISDN Station’s behavior.
4) ISDN Intercom Call.
Any station can call ISDN Devices by dialing station no. S-Interface has two stations no. So, user
can call ISDN Devices by dialing one of two pre-assigned stations no. There is no difference
between calling ISDN Devices with the two stations no which is assigned the same S-Interface.
If ISDN Device is set to Sub Addressable ISDN, it needs further one digit for calling that ISDN
Device.
5) ISDN CO Line Access.
CO Line Access of ISDN Device is the same as that of Single Line Telephone ( SLT )
6) CO Line Hold.
In GDK-20W, system does not use DTMF Receiver for recognizing user’s dialing digit. So if user
want to use Hold/Transfer Feature on ISDN Device, ISDN Device has the capability of sending
Keypad Facility Information on the Information Message.
If possible, holding CO Line Call, send “*#” ( Keypad Facility ), then connected CO Line Call is held
and user can hear Intercom Dial Tone.
Retrieving Held CO Line, send “*#” ( Keypad Facility ), then the held CO Line Call is retrieved.
Please consult your ISDN Device’s Manual for sending “Keypad Facility” after connection.
7) CO Line Transfer.
