Toshiba Strata CTX100 User Manual

Enhanced 911 calling means the routing of a call to the appropriate Public Safety Answering 
Position (PSAP) accompanied by Caller Emergency Services Identifier (CESID). The CESID 
identifies the location to which emergency services are to be sent. The Strata CTX can use two 
types of trunks to deliver E911 calls: ISDN Primary Rate Interface and CAMA (Centralized 
Automatic Message Accounting) trunks. Each 911 call generates an SMDR record at the 
beginning of the call to enable the business to initiate its own emergency response. Internal 
emergency destinations can also be automatically included in an emergency call. E911 calls can be 
routed across a Strata Net network for connection to the public network.

The External Amplified Speaker (HESB) is a six-inch, three-watt speaker with a three-watt 
amplifier built into a wooden speaker box. The amplified ringer can be used to:

•

Amplify the ringing on a digital telephone.

•

Provide a paging amplifier/speaker.

•

Create an amplified talk-back speaker arrangement in an area where a telephone is not needed. 
The HESB is installed as a speaker and connected to a door phone unit that is used as the talk-
back microphone.

Amplified ringing can improve call handling in noisy areas where non-amplified ringing on a 
phone may not be heard.

A paging speaker ensures that paging announcements can be clearly heard throughout an area. In 
an area where a DKT is not needed, a talk-back speaker provides a cost-effective communications 
solution.

The number of HESBs that can be installed per system depends on the function of the HESB. Any 
number of HESBs can provide loud ringers for digital telephones. Only one HESB can be installed 
if it is used as a paging or an amplified talk-back speaker.

A BHEU interface and an HESC-65A cable are required for each digital phone that has a 
loud ringing bell. A 3000- or 2000-series digital telephone that has been upgraded with a 
data interface unit can be upgraded with the BHEU options, but older telephone models 
cannot.

This is an optional button that can be assigned on digital telephones. It can be used either to 
disconnect a line and regain CO dial tone, or to gain access to Centrex features. The timing choice 
is set system wide through system programming. Standard telephones can dial an access code to 
flash Centrex lines.

CO line ringing can be assigned to ring a specified [DN] on a station, a [DN] appearing on 
multiple stations, a Pilot [DN], a direct appearance of the CO line, a Pooled appearance of CO 
lines, or Group CO line appearance. These assignments direct the ringing of the incoming call 
based upon the three Day/Night Modes of operation and offer immediate and two delayed ringing 
parameters. The delay parameters are assigned for each incoming Line Group.
