A dialing pause can be manually inserted by pressing the PAUSE button, or can be automatically inserted after a user-dialed code, such as a Host PBX Access code or Special Carrier Access code. The length of the pause can be specified through system programming.

• 1.5.4.5 Pause Insertion
• 1.5.4.6 Host PBX Access Code (Access Code to the Telephone Company from a Host PBX)
• 1.5.4.7 Special Carrier Access Code

An extension user can dial preprogrammed emergency numbers (

Emergency Number [304]) after seizing a CO line regardless of the restrictions imposed on the extension.

•

A specified number of emergency numbers can be stored.

•

Emergency numbers may be called, regardless of Toll Restriction (TRS) level (

1.8.1 Toll Restriction (TRS)), even when:

—

in Account Code–Forced mode (

1.5.4.3 Account Code Entry)

—

in Extension Lock (

1.8.2 Extension Lock)

An account code is used to identify outgoing CO line calls for accounting and billing purposes. The account code is appended to the Station Message Detail Recording (SMDR) call record. For example, a firm can use an account code for each client to determine which calls were made for which client, and can submit a bill to the client according to the client's account code as shown on the SMDR call record.
There are two methods of entering account codes explained below.
One of the methods is selected for each extension based on Class of Service (COS) programming (

Account Code Mode [508]).

Mode

Description

Option

An extension user can enter an account code, but is not required to.

Forced

An extension user must always enter an account code before seizing a CO line. This method ensures extension users will not forget to enter account codes.

•	An account code can be stored in Memory Dialing (One-touch Dialing, for example).
•	Account Button A flexible button can be customized as the Account button. The Account button is used in place of the feature number for entering an account code. This button is useful because it can be used at any time, while feature number entry is allowed only when hearing a dial tone before seizing a CO line.
•	Account code entry after receiving a disconnection signal from a CO line must be done while hearing a reorder tone. Otherwise the SMDR call record is logged and entry becomes impossible afterwards.
•	If an account code is entered more than once, the code entered last is logged in the SMDR.
•	Even in Forced mode, emergency numbers can be dialed without an account code. ( 1.5.4.2 Emergency Call)
•	Proprietary telephone (PT) users can also enter an account code for incoming CO line calls during a conversation.
•	Verified Code Entry To identify who made a CO line call for accounting and billing purposes, a verified code can be used. This code can be used at any extension. ( 1.8.5 Verified Code Entry)

User Manual

1.2.1 Basic Calling

The dialing mode (rotary or tone) can be selected for each analog CO line through system programming (

LCOT Dialing Mode [410]) regardless of originating extension (under contract with the telephone company).

Mode

Description

DTMF (Dual Tone Multi-Frequency)

Numbers dialed by an extension user are transmitted to the CO line using analog tones.

Pulse Dial (Rotary)

Numbers dialed by an extension user are transmitted to the CO line using analog pulses.

•	Pulse to Tone Conversion It is possible for an extension user to temporarily switch from Pulse mode to DTMF mode in order to access special services such as computer-accessed long distance calling or voice mail services. To switch to DTMF mode, wait for a preprogrammed time period (Default: 5 seconds) after the CO line is connected, or press . This feature works only on CO lines set to Pulse mode. DTMF mode cannot be changed to Pulse mode.
•	It is possible to select a pulse rate for the CO line port which has been set to Pulse mode ( LCOT Pulse Rate [411]). There are two pulse rates: Low (10 pps) and High (20 pps).
•	It is possible to assign the minimum duration of the DTMF signal sent to the CO line port which has been set to DTMF mode ( LCOT DTMF Minimum Duration [412]).

A dialing pause of a preprogrammed length (

LCOT Pause Time [416]) can be inserted manually or automatically when dialing.
Manual Insertion: Pressing the PAUSE button.
Automatic Pause Insertion: A pause will be automatically inserted between the user-dialed codes below and the following digits.

a)	Host PBX Access code ( 1.5.4.6 Host PBX Access Code (Access Code to the Telephone Company from a Host PBX))
b)	Special Carrier Access code ( 1.5.4.7 Special Carrier Access Code)
c)	Second Dial Tone Waiting code

•	The length of a pause is programmable for each CO line.
•	Numbers stored in Memory Dialing can contain pauses.
•	Pressing the PAUSE button while dialing a number inserts a pause of the preprogrammed length.
•	When a preprogrammed Second Dial Tone Waiting code is dialed after seizing a CO line, pauses are inserted a preprogrammed number of times after the code.

1.5.4.6 Host PBX Access Code (Access Code to the Telephone Company from a Host PBX)

This PBX can be installed behind an existing host PBX. This is performed by connecting extension ports of the host PBX to CO line ports of this PBX. A Host PBX Access code assigned through system programming (

Host PBX Access Code [471]) is required to access the telephone company from the host PBX. The CO Line Access number of the host PBX should be stored as a Host PBX Access code on a CO line group of this PBX basis.
A pause of a preprogrammed length (

LCOT Pause Time [416]) will be automatically inserted between the user-dialed Host PBX Access code and the following digits. (

1.5.4.5 Pause Insertion)

[Example]

Note
	In this example, "0" should be assigned as a Host PBX Access code for CO line group (TRG) 1 of this PBX.

•	TRS TRS checks only the dialed telephone number excluding the Host PBX Access code when accessing the telephone company through the host PBX. ( 1.8.1 Toll Restriction (TRS))
•	SMDR The Host PBX Access code can be logged by SMDR along with the dialed number when accessing the telephone company through the host PBX.
•	To log by SMDR only long distance calls (not local calls) originated via a specific CO line group, assign the long distance call code as a Host PBX Access code to the CO line group.

If the PBX has access to multiple telephone companies, a Special Carrier Access code assigned through system programming (

Special Carrier Access Code [303]) is required every time a CO line call is made.
A pause of a preprogrammed length (

LCOT Pause Time [416]) will be automatically inserted between the user-dialed Special Carrier Access code and the following digits. (

1.5.4.5 Pause Insertion)

•	TRS TRS checks only the dialed telephone number excluding the Special Carrier Access code. ( 1.8.1 Toll Restriction (TRS))
•	If this PBX is installed behind an existing host PBX: A Special Carrier Access code and a Host PBX Access code should be assigned separately–these codes cannot be assigned together as one code. ( 1.5.4.6 Host PBX Access Code (Access Code to the Telephone Company from a Host PBX))

•

Button Assignment
A flexible button can be customized as a G-CO, L-CO, or S-CO button as follows:

Type

Assignable parameter

Loop-CO (L-CO)

Any CO line group that is made available for Idle Line Access through system programming is applied.

Group-CO (G-CO)

A CO line group is assigned.

Single-CO (S-CO)

A specified CO line is assigned.

It is possible to assign CO lines in the following ways:

—

The same CO line to the S-CO button and to a G-CO button

—

The same CO line group to more than one G-CO button

—

More than one L-CO button

Dialing the CO Line Access number selects a CO button according to the following priority: S-CO

G-CO

L-CO

•

Direct CO Line Access

An idle CO line is selected from the CO line groups assigned for Idle Line Access. If multiple CO line groups are available, the CO line group hunting sequence can be determined through system programming.

•

CO Line Hunting Order for Idle Line Access and CO Line Group Access
The CO line hunting sequence in a CO line group (from lowest numbered CO line, from highest numbered CO line or rotation) can be determined through system programming.

•

A company name or customer name can be assigned on a CO line port basis (

LCOT CO Line Name [401]) so that the operator or extension user who is answering the call can view the destination which the caller is trying to reach before answering.

•

It is possible to identify the CO line port that has a CO line connected to it (

LCOT CO Line Connection [400]). This prevents extension users from originating a call to a CO line which is not connected.
