CAUTION If you have not configured the DELST-UI using
software, do not connect any cables. Refer to
the section titled Software Setup before
proceeding.
ACHTUNG Wenn Sie die DELST-UI-Einheit nicht unter
Verwendung von Software konfiguriert haben,
dürfen Sie keine Kabel anschließen. Lesen Sie
die Informationen im Abschnitt zum Einrichten
der Software (Software Setup), bevor Sie mit
diesem Schritt fortfahren.
ATTENTION Si vous n'avez pas configuré le DELST-UI à
l'aide d'un logiciel, ne connectez aucun câble.
Reportez-vous à la section intitulée Software
Setup (Configuration du logiciel) avant toute
opération.
PRECAUCIÓN Si no ha configurado el DELST-UI a través del
software, no conecte ningún cable. Consulte la
sección referente a la instalación y
configuración del software antes de continuar.

Safety
xvi DELST-UI Local Management
CAUTION DO NOT plug the ISDN cable into the ISDN
wall jack until after the software setup has
been completed by using either QuickSET or
the management procedure. If the ISDN cable
is plugged in prematurely, before the host unit
is configured, the telephone company may
disable the ISDN line for a period of time. Plug
in the cable as a final step, after you have
configured the DELST-UI.
ACHTUNG Stecken Sie das ISDN-Kabel erst dann in die
SteckdosefürdenISDN-Anschluß, NACHDEM
die Software vollständig entweder mit
QuickSET oder dem Verwaltungsverfahren
eingerichtet wurde. Wenn das ISDN-Kabel vor
der Konfiguration der Host-Einheit
angeschlossen wird, könnte es vorkommen,
daß die Telefongesellschaft die ISDN-Leitung
für einige Zeit sperrt. Das Kabel sollte deshalb
erst im letzten Schritt angeschlossen werden,
nachdem Sie die DELST-UI-Einheit
konfiguriert haben.
ATTENTION NE PAS connecter le câble RNIS (ISDN) à la
prise RNIS murale avant d'avoir terminé la
configuration du logiciel soit à l'aide de
QuickSET, soit par la procédure de gestion. Si
le câble ISDB est connecté trop tôt, avant
d'avoir configuré le système hôte, la
compagnie de téléphone risque de désactiver
la ligne RNIS pendant quelque temps. Ne
connectez le câble qu'après avoir configuré le
DELST-UI.
PRECAUCIÓN NO conecte el cable RDSI a la toma RDSI
mural hasta que se haya completado
totalmente la instalación del software mediante
el uso de QuickSET o el procedimiento de
gestión. Si se conecta prematuramente el
cable RDSI, antes de que se configure la
unidad central, la compañía telefónica puede
desactivar la línea RDSI durante cierto período
de tiempo. Conecte el cable durante el último
paso, tras haber configurado el DELST-UI.

DELST-UI Local Management Guide 1-1
CHAPTER 1
INTRODUCTION
This chapter provides information about the features and performance of
the DELST-UI. It also briefly explains Integrated Services Digital
Network (ISDN), call back-up, and the WAN protocols supported by the
DELST-UI.
Note the following requirements for successful operation of this device:
•Install the DELST-UI in a Wide Area Network host platform. Refer to
Chapter 2 for directions on installation procedures. Refer to the
appropriate host platform manual for other installation and
troubleshooting procedures.
•Use the Graphical User Interface QuickSET to fully configure the
DELST-UI. Due to the automation of setup features, QuickSET use is
strongly recommended. However, Chapter 3 contains additional
information on configuring the DELST-UI, which can be done
independently of QuickSET.
1.1 DELST-UI FEATURES
The DELST-UI provides ISDN 128 Kbps Basic Rate Interface (BRI) in a
backup or fail-over capacity for other devices in which the DELST-UI can
be installed. The DELST-UI provides an ISDN back-up link for a remote
site or branch office when the primary connection for a frame relay or
leased line is lost or becomes disabled.
The device or module in which the DELST-UI is to be installed
may be referred to in this document as the host platform.

Chapter 1: Introduction
1-2 DELST-UI Local Management Guide
1.1.1 Performance
The capability of the DELST-UI is 128 Kbps when both B Channels are
active.
There are several user-configurable timers that control the connect and
disconnect time-outs to provide optimum performance. These are detailed
in Chapter 3.
1.2 ISDN
ISDN provides inexpensive switched digital access to remote sites. The
ISDN BRI standard provides for two high-speed 64-Kbps bearer (B)
channels used for voice or data connections and one 16-Kbps signaling
data (D) channel used for call setup, signaling, and other information.
ISDN allows all types of information to be transmitted including voice,
data, fax, and video. Multiple devices can be linked to a single ISDN
connection, each having their own telephone number. Two or more
channels can be combined into a single larger transmission pipe offering
variable transmission speeds.
1.3 ISDN CALL BACK-UP
The ISDN call back-up feature provides a back-up link for a remote site
or branch office when one or more primary WAN interfaces for a frame
relay circuit or a nailed-up PPP connection fails. The DELST-UI serves
as the backup medium for this primary connection, using the ISDN
interfaces to back-up any primary interfaces that have been configured for
ISDN back-up.
The following are two reasons to use ISDN call back-up:
•Hardware failure of a nailed-up PPP connection
•PPP fails to connect (software problem)
Use call back-up if either of the following conditions exist when using
Frame Relay:
•DLCI circuit fails to connect in 12 minutes
•DLCI goes inactive
