Ease of access to multiple types of network facilities (provided for minimum cost) is managed by:

Automatic Route Selection (ARS) allows the customer to dial a standard DDD

number.

ARS selects the preferred route and does any number conversions required

for the

facilities selected.

System 25’s Virtual Facility feature provides convenient and inexpensive access to OCCs. This feature provides access to OCC facilities over a user specified p h y s i c a l facility; dedicated OCC trunks are not needed. Local OCC access numbers and

account codes are automatically added by System 25. System 25’s Virtual Facility feature is fully integrated with its ARS, Toll Restriction, and SMDR/CAS features.

Repertory

Dialing allows multiline

voice

terminal

users

to store

a telephone number

or account and associate that number with a button on their voice terminal. Pressing a Repertory Dial button is equivalent to dialing the stored number (one- touch dialing).

System Speed Dialing allows all users to dial 90 selected numbers using three-digit codes. Users can also program up to seven Personal Speed Dial Numbers which are

accessible only from their terminals. System Speed Dialing can be used by the system administrator to hide business account codes from users.

Pooled Facility-Dial

Access

allows

both

multiline and single-line voice terminal users

to access a common

pool

of trunks

for

outgoing calls by dialing a facility access code,

or, on multiline voice terminals, by pressing a button . This grouping provides resource pooling which results in better service with a given number of trunks.

Personal Lines provide dedicated outside lines for multiline voice terminal users. Personal lines are accessed via a dedicated feature button. Up to sixteen terminals may share a personal line.

Third-Party Call Setup allows PCs to set up calls between a System 25 voice/data

terminal and any other

facility.

A PC application program could use this capability

to retrieve information

from a

database.

Last Number Dialed, Repertory Dialing and Speed Dialing are also applicable to dialing and managing internal calls. Personal lines provide both incoming and outgoing service.

Internal Call Movement

Typically, about 40 percent of PBX calls are internal calls, call transfers to another location, conference of multiple locations, temporarily suspended calls, page to locate the called party, etc. Rapid placement of internal calls and easy call movement from the answering station to a new station are supported in System 25 with numerous features.

To provide easy internal call setup, System 25 provides the following features.

Direct Station Selection (DSS) allows one-button access from a multiline voice terminal to another voice terminal, a pooled facility, paging zone or DGC group. The DSS status LED reflects the idle/busy status of the associated termination point. This feature is used to track and contact frequently called associates.
