Strata CTX28 Overview 1
This chapter provides a system overview of the
Strata CTX28 telephone system.
The Strata CTX28 system is a compact system that
provides large system features (for dimensions, see
Table 1). The CTX28 is designed for wall mounting
and occupies very little space.
The CTX28 does not require processor licenses for
Line/Station ports, DTMF Receivers, etc.
The CTX28 basic system comes with eight digital
telephone ports, three CO line ports with Caller ID
interface and one standard telephone port.
The system can be expanded to 16 digital telephone
ports, six CO line ports with Caller ID Interface and
two standard telephone interfaces.
The GCTU processor comes with a built-in
maintenance modem, one Music on Hold (MOH)
interface, one External Paging interface, one Relay
contact, and one SmartMedia card slot. The
processor is a standard part that is shipped inside
the CTX28 cabinet shipping box. The GCTU plugs
into a dedicated cabinet slot.
An optional four port voice mail circuit card (GVMU) can be added to provide Auto Attendant/
Voice Mail features including: Voice Mail Call Monitor, Voice Mail Soft keys and Record to Voice
Mail. The GVMU provides 20 hours of voice recording storage or up to 1,024 saved messages.
The GVMU plugs into a dedicated cabinet slot and requires no additional hardware to provide its
full set of features.
The plug and play CTX28 is easy and very cost effective to install. The system is pre-programmed
to match all related voice mail programming in the GVMU Voice Mail system. This includes
station numbers, mailboxes, voice mail hunt groups, voice mail station IDs and many other items
which are listed in the CTX28 Installation documentation. The pre-programmed data is set when
the processor is initialized even if the Expansion cards or GVMU Voice Mail system is not
installed prior to system initialization.
