Chapter 2 - Features and Operation
ISDN
Description
Current XTS software supports Primary Rate Interface (PRI) and Basic Rate Interface (BRI) 
Integrated Services Digital Network (ISDN) circuits. The PRI provides 23 bearer channels and 
one data channel (23B+D). The BRI provides two bearer channels and one data channel 
(2B+D).
Calling Number and Called Number services are supported with the PRI and BRI. Calling 
Number services will be routed in the same manner as ANI/ICLID calls using the ICLID route 
table and name/number translation table.
The rules and conditions of ANI/ICLID are the same, and still apply to Calling Number service 
on ISDN lines. Called Number services will be routed using the DID/DNIS route table. The 
rules and conditions of DID and DNIS are the same, and still apply to ISDN Called Number 
service on ISDN lines.
Channels

The bearer channels (B channels) transport voice information to and from the Central 
Office.

The data channel (D channel) controls all signaling information for the bearer channels.
PRIB/BRIB

The PRIB only supports the NI-2 standard. The BRIB only supports the NI-1 standard.

Neither the PRIB nor the BRIB will support the trunk features of paging, reseize, queuing, 
or RAN support.

Vodavi has successfully integrated its BRI ISDN with the Lucent 5 ESS and DMS 100 
Central Office and its PRI ISDN with the Lucent 5 ESS, Siemens, Stromburg Carlson, and 
the DMS 100 Central Offices. Vodavi ISDN should interface with all Central Office 
switches, but this has not been verified. Therefore some delays in service may be 
experienced.
Extended Key Telephone Service
Description
Extended key telephone service (EKTS) is a feature that can be provided on BRI ISDN to 
simulate standard analog DID lines. This allows several different numbers to be shared by a 
single BRI circuit.
Due to the decline in telephony tariffs, there is an increasing demand for BRI ISDN features. A 
BRI circuit allows two simultaneous calls to be handled, due to its technical specification. BRI 
circuits have two B-channels at 64 kilobytes per second and one D-Channel at 16 kilobytes 
per second.
The Bearer (B) Channels are designed for PCM (voice) and the Data (D) Channel is designed to 
carry information specific to each incoming and/or outgoing call. 
						

							2-174ISDN
Chapter 2 - Features and Operation
The EKTS feature allows a single ISDN Service Profile Identifier (SPID) or B-channel to support 
multiple directory numbers. A SPID is a number that telephone company switching 
equipment uses to track configuration information for each terminal adapter connected to 
an ISDN telephone line. The telephone company should provide SPIDs at the same time that 
the ISDN directory numbers are assigned. A directory number is another term for a telephone 
number.
If an application requires EKTS, be aware that BRI ISDN handles a busy number differently 
than a DID circuit. When the called number is busy, BRI will issue a busy signal, but a DID 
circuit will ring another line in the circuit. The busy signal is provided by the telephone 
company, therefore the call is not presented to the Vodavi telephone switch and it is not 
forwarded to voice mail. For example, a caller dials 480-443-6000 and is connected to the 
extension. While the first caller is still connected, a second caller dials the same number. The 
second caller will receive a busy signal that is provided by the telephone company.
In a normal BRI application, two numbers are assigned to each BRI circuit, which consists of 2 
channels. There can be a maximum of 4 circuits equipped to handle 8 channels per BRIB. This 
is a direct number-to-channel relationship without hunting capability. Most circuit providers 
offer an optional “hunting” feature capability on BRI circuits. This optional feature allows 
numbers to hunt for idle channels on the BRIB up to a maximum of 8 channels per BRIB, 
assuming four BRI circuits were installed.
In EKTS applications, you can have a maximum of 64 DID numbers hunt to one BRIB. Hunting 
cannot be accomplished between BRIBs, nor will the hunting feature allow calls to be routed 
to a busy DID number.
Programming Steps
1. Press FLASH 40, Page A, Button #16 to enable or disable extended key telephone 
service. The following message displays:
2. Enter a 0 or 1 on the dial pad to enable/disable this feature.
[0] = Disabled
[1] = Enabled
3. Press HOLD to save the entry. A confirmation tone sounds and the display updates.
4. Reset the KSU,
-or-
Reset only the card using “config” without resetting the whole telephone switch. To do 
this, type config at the Enter Password prompt. Then type rk (k = slot number). For 
example, r2 indicates that the BRI card is in slot 2.
DEFAULT … EKTS is disabled.
EKTS 0-1
DISABLED
Shared numbers are routed using the standard DID tables (Flash 43 and 44).
Numbers that are not shared will only ring on the designated channel. If the 
designated channel is busy, the caller will receive a busy signal.

Chapter 2 - Features and Operation
Conditions
» To support EKTS, telephone switch software must be 3.0G or higher and BRIB firmware 
must be 0.1G or higher.
» When ordering EKTS, request basic EKTS, not cache EKTS. Vodavi supports Basic EKTS. The 
EKTS caching option is not supported by Vodavi. Caching is normally used when an ISDN 
telephone instrument is used on the customer premise.
» Order only one SPID and one primary directory number per channel.
» Secondary directory numbers (e.g., DID numbers) are shared across each channel to a 
maximum of 32 channels.
» Sharing can only be done between circuits on one card.
» Like DID, EKTS can be programmed to route calls using up to 7 digits. By default, only the 
last three digits are analyzed for routing.
Directory Number - BRI
Description
The Directory Number feature is used for BRI programming on a per-channel basis. Initializing 
terminals are required to store a 7-digit Directory Number in order to perform the 
compatibility checking procedures that are part of call termination. In addition, this Directory 
Number is desirable in call originations in order to remain in synchronization with the Stored 
Program Control Switching System (SPCS).
Programming Steps
1. Press FLASH and dial [40]. The following message displays:
2. Enter a valid number for the range of lines being programmed. If only one line is being 
programmed, enter that number twice (001 001).
3. Press HOLD to save the entry. A confirmation tone sounds and the display updates. 
Flexible Button #19 (Page A) is lit.
4. Press the Page B flexible button (Button #20). The following message displays:

SPID
Description
When you order an ISDN line, your phone company will give you a Service Provider Identifier 
(SPID) for every phone number that you have. Each ISDN BRI line typically has two phone 
numbers and thus two SPIDs. The SPID is an eight to 24-digit number that identifies the 
services that you ordered.

ISDN Programming  - Page A
Description
This section describes the procedures and steps necessary to program ISDN attributes. When 
entering the ISDN attributes portion of the database, the programmer may decide to enter 
information for a range of slots or one specific slot. Range programming lets the programmer 
change a specific parameter or a few parameters for an entire range of slots, leaving intact 
the remaining data fields that do not require change. Those data fields continue to operate 
with the previously programmed data. By default, Page A is shown.
Programming Steps
1. Press FLASH and dial [45]. The following message displays:
