Definition
An ISDN multi-device connection enables users to connect multiple ISDN terminals (such as Internet and ISDN video devices) on an ISDN S0 applications bus. You can use the direct inward dialing (DID) number field to assign multiple subscriber numbers (MSNs) that will uniquely identify the devices.

Multiple subscriber numbers (MSNs) are used to identify ISDN terminals connected to an S0 bus in the Hicom 150 E systems. MSNs are 11 digits in length. They are entered in the DID number field in system administration.
You can assign each ISDN terminal one or two MSNs, depending on the application. A device requiring 64 Kbps of bandwidth must be assigned one MSN; a device requiring 128 Kbps of bandwidth must be assigned two MSNs. The call number associated with the MSN is dialed to reach the device during an internal data or voice transaction.

Requirements/Conditions
Definition
North American ISDN PRI most often requires that the B channel voice path cut-through to the network before connecting. This cut-through operation is different than most other parts of the world. For this reason, the ISDN service providers often provide in-band tones or announcements that require a cut-through of the voice path.

Electronic Key Telephone System (EKTS) is a National ISDN-1 standard that supports call appearances according to the directory number. This group-sharing capability associates a telephone on any interface with a particular directory number. EKTS enables sharing of telephone features like call management, caller ID, conference calling, and call forwarding.

Call Appearance Call Handling Electronic Key Telephone System (CACH EKTS) simulates multiple call handling at a single desktop station. Users can receive multiple calls for the same directory on several ISDN lines using one of the call appearance IDs that is assigned to the directory number. With this feature, the CO can offer a call on multiple interfaces because the directory number call appearances are shared. This allows the Hicom 150 E Office to respond to the call with an idle interface. CACH is called call appearance identification (CAID) in the Hicom 150 E Office.

With called and calling party number display services like dialed number identification service (DNIS) and automatic number identification (ANI) are provided by the network. DNIS is for T1 digital trunks and ANI is for PRI trunks. The calling party number (CPN) is displayed on a suitable display telephone.
With this feature, the system performs the following functions:
1. | Checks the calling number against any ANI or DNIS table entries |
2. | Translates the digits into an account number, customer name, or company name |
3. | Routes the call |
4. | Displays the information on the telephone display |
Users can override this feature system wide.
