Carrier codes

In some cases, long distance service uses the same lines as local service but

is switched to a specific carrier using an access number, which is sometimes

referred to as an carrier access code (CAC). Route programming can include

the access number so the users do not have to dial it every time they make a

long distance call.

BCM feature access codes

This section describes BCM feature access codes.

Direct dial set configuration

The Direct dial setting allows you to dial a single system-wide digit to call a

specific telephone, called a direct dial telephone. The most common example

of a direct dial set is a telephone for an operator, a receptionist or an attendant.

You can program a maximum of five direct dial sets on the system, however,

you can only specify one direct dial number for the system.

Interaction between access codes

The following list describes the interaction between different access codes:

• External line access code: If the DN length is changed, and the changed

DNs conflict with the external line access code, the setting changes to

None.

• Direct dial telephone: Another direct dial telephone, an extra dial

telephone, can be assigned for each schedule in Services programming.

If the DN length is changed, and the changed DNs conflict with the Direct

dial digit, the setting changes to None.

• Public/Private Auto DN: The length of the Auto DNs are the same as the

Public or Private Received Number Lengths specified under Configuration

> Telephony > Dialing Plan. The public/private Auto DN is cleared if the

corresponding Received Number Length is changed.

• Public/Private DISA DN: The length of the DISA DNs are the same as the

Public or Private Received number length specified under Configuration >

Telephony > Dialing Plan. The public/private DISA DN is cleared if the

corresponding Received number length is changed.

Attention: When configuring a private network, ensure the numbering plan

does not conflict with the public telephone network. For example, in North

America, using “1” as an access code in a private network, conflicts with the

PSTN numbering plan for long-distance calls.

The following codes/digits must not conflict:

• park prefix

1 2 ... 57 58 59 60 61 62 63 64 65 66 67 ... 323 324
