7.17 U.S. ISDN Features (for U.S. Only)

7.17.1 Multi-Device Connection

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.

7.17.2 Call-By-Call Service Selection

Definition

Call-by-Call service selection (CBC) lets the user select a different type of service for each channel, such as INWATS channels and some OUTWATS channels within the same trunk group.

The following are the four main features provided through call-by-call (CBC):

Foreign Exchange Non-ISDN Facility
This trunk type enables users to originate or terminate calls as if there was a local CS in the foreign (remote) central exchange office. Access to the foreign exchange (FX) is possible via LCR or trunk group access codes.
Tie Trunk Non-ISDN Facility
This trunk type enables users to connect to a privately leased analog Tie Trunk network. Access for originating calls is possible through LCR. Terminating Tie Trunk calls are routed according to the called party number (CdPn).
OUTWATS Facility
This feature allows customers to place calls to certain areas at special lower rates.
INWATS Facility
This feature supports the 800 area code that provides callers toll-free access to the terminating party. This is a terminating only service.

7.17.8 Special Access Selection

Definition

With this feature users can select specific access codes. Hicom 150 E Office supports the following four options:

Local Exchange Carrier (LEC) Operator Access
The system routes calls through the PRI to the network after the user dials 0 to connect to the LEC operator.
Inter-exchange Carrier (IEC) Operator Access
After the user dials an operator access code, a carrier identification code (CIC), and a 0, the system routes the call through the PRI and to the network, connecting the call to the IEC operator.
Operator Assisted Credit Card Call Access
This feature routes PRI calls to the network using an operator access code, a 0 or 01, and a called party number (CdPn), allowing operator assisted calls with a calling card.
N11 Access
Most commonly used for 911 access, this feature routes PRI calls to the network via an operator access code and N11, where N is any digit from 1 to 9.

7.17.10 Multiple Subscriber Number

Definition

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.

MSN 
MSNs are assigned in the DID number field for each ISDN terminal. This number is used as the internal SPID for the device. 
Primary Directory Number (PDN) 
The PDN associated with public network BRI link must be entered in the DID field for the ISDN terminal to initiate calls to the external network. 
MSN for internal use only 
Enter a seven-digit number not associated with the PDN in the DID field. 
External SPIDs 
The public network SPIDs for the ISDN links can be assigned to any station in the system. 
B channels 
The number of external data calls is limited to the number of B channels installed in the system. 
Access 
B channels are dedicated to the specific ISDN terminal and should be placed in a separate trunk group to ensure access if more than one BRI trunk is installed. 
MSN 
If the MSN for a Setup is missing or invalid, a default MSN appropriate to the situation is used. When a station number is specified that is already in use (optiset E), the Setup is rejected. If an MSN is too long, a right-justified evaluation of the digits is performed. 

7.17.11 Calling Line Identification Presentation

Definition

The calling line identification presentation (CLIP) feature transmits the caller's own station number to the interface called. The station number can be displayed on suitable telephones. Station number transmission must be supported in the public network.

Definition

All calls for the ISDN port can be forwarded. Three different types of call forwarding (CF) are available:

Call forwarding unconditional (CFU)
All calls for the ISDN port are immediately forwarded to any port.
Call forwarding busy (CFB)
Same as CFU but only for busy trunk.
Call forwarding no reply (CFNR)
Same as CFU but only if the call is not answered within a specified period (15 s).

7.17.13 Call Hold

Definition

Call hold (CH) is important in conjunction with other features such as call waiting, consultation hold, toggle, and three-party conference. The ISDN port on hold receives an indication of the hold state and retrieval of the call.

7.17.21 B Channel Cut-Through Operation Mode

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.

Definition

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.

7.17.26 Call Appearance Call Handling Electronic Key Telephone System

Definition

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.

In a basic EKTS system CAID values are not supported. The AT&T 5E and Siemens EWSD central offices support the CAID format. The Northern Telcom central offices use phantom DID numbers instead of CAID values. 

7.17.27 Called and Calling Party Display

Definition

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.
