Chapter 2 - Digital Station Features
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 4 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.
Conditions
BRI EKTS support is available in Vodavi telephone systems with software version 3.0G and
higher.
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.
EKTS does not require a line appearance on a specific telephone because the BRI terminates
directly into the KSU.
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.
Keyset Mode (Digital KTU Only)
The Keyset Mode feature allows the station user to determine the mode in which the Digital
Telephone with CTI Box (optional) operates. The five modes are: Inactive mode, PC Phone
mode, ATD Command mode, ATH Command mode and CKTU mode. Through the use of a
dial code, the station user can also determine the baud rate for each mode selected. This
setting is stored in back-up memory in the event of a power outage or system reset.
Last Number Redial
The Last Number Redial (LNR) feature permits the automatic redialing of the last telephone
number dialed on an outside line. Up to 24-digits can be stored. Outside line selection of the
same line used is automatic.
