CHAPTER 1

APRIL, 1990

NIGHT CHIME(S) control is provided when the system is equipped with an ECR-E ETU. The ECR-E ETU contains ten relays. Three of these relays (one per tenant) can be programmed to provide closures when incoming CO/PBX calls are received in the Night Mode. The Night Chime feature is used after normal working hours to alert night personal of incoming outside calls. Locally provided external bells and/or amplifiers are controlled by the system. ANA, DIT or DID trunks will not activate the Night Chime relay(s).

NIGHT TRANSFER is a function controlled only by the Attendant Positions (with or without DSSIBLF Consoles). When an Attendant sets the system into Night Mode, it provides a change from the Day Mode ring assignment and enables the Night Call Pickup

and ANA features (if so programmed), in systems supported by a CPU-EB2 (or higher revision level) ETU.

OFF-HOOK VOICE ANNOUNCEMENT can be provided to any Multiline Terminal (except ETE-8( )

and ETE-16-2) with the installation of the DPA-E Unit. The DPA-E Unit provides a Multiline Terminal with a secondary voice path, which allows that station to receive a Voice Announcement while on a handset call with someone else. This requires the Multiline Terminal to be supported by an ESI-EB ETU (located in any of the first three CCUs), as well as being programmed as a Dual Path terminal.

OFF-HOOK RINGING allows a Multiline Terminal user to hear when an incoming call is signaling while the Multiline Terminal handset is in use. The off-hook ring is provided at a reduced level. This feature can be disabled in programming if not desired.

OFF-PREMISES EXTENSION is provided by the connection of a standard Single Line Telephone (DTMF) remotely located from the main installation site, to access the system’s features with the same capabilities as an on premises Single Line Telephone. Locally provided Dial Long Line (DLL) equipment is required for this feature.

PC VOICE DIALING allows the system user to dial

telephone numbers for voice calls from the PC Keyboard. Modem Pooling is used in conjunction with this feature.

PC Voice Dialing and Modem Reserve capabilities can be allowed through system programming if the system is supported with a CPU-EB3 (V3.05) ETU (or higher revision level). PC Voice Dialing requires the use of a MFR-EA ETU.

Each modem (four maximum) must be able to respond
to Keyboard		commands	such		as	the	HAYES@
Commandset,		provide	auto	answer,		and	must	be	1
supported	by an SLI-E ( ) ETU port, a Multiline
Terminal	with LCD (equipped with a DTA-E Unit),
and supported by an ES&EB ETU port.
POOLED LINE allows multiple trunks to be assigned
to a multiline		Terminal’s	line	key for		incoming		and
outgoing calls. This feature allows station users to
answer	and	originate	outside		calls	for	any	line
belonging to a Pooled Line Group with one Pooled Line
key. Up to eight Pooled Line Groups can be assigned

per system. This feature requires the support of a CPU-EB3 (or higher revision level) ETU.

POWER FAILURE TRANSFER ensures that a customer can always have access to the central office network, even during a commercial power outage.

This feature requires the use of Single Line Telephones supported by SLI-EB ETUs. If power fails to support the Electra Mark11 CCUs, the CO Tip and Ring are

automatically transferred to the Tip and Ring of a

preselected (and cross connected) Single Line Telephone. These SLTs may function in the system during normal operation, or only during power failure, depending upon the customer requirements.

PRIME LINE ASSIGNMENT simplifies the use of the system by providing automatic selection of a line. When a Multiline Terminal, programmed for Prime Line Assignment, goes off-hook, the assigned extension

or outside line key is seized automatically. This feature seizes the line when it is IDLE. When a Single

Line Telephone, programmed for CO Prime Line Assignment, goes off-hook the assigned CO line is seized. To release this line and obtain a new internal dial tone, hookflash, and dial the preprogrammed release code [when the system is supported with a CPU-EBB (or higher revision level) ETU].

Variations of this feature are accomplished when the

system is programmed for Prime Line pickup for

incoming calls, or the terminal is programmed for Ringing Line Preference and Prime Line.

PRIVACY ON ALL CALLS provides the secure knowledge that no one can listen to your ongoing conversation. Only the person holding a conversation can allow another party to enter the conversation (via

Add-On Conference). All lines in the system are provided with complete Privacy.

PRIVATE LINES can be assigned via the Flexible Line Assignment feature. Restriction assignments can be used to assure that a line is made private.
