Land Line Calling Features


In accordance with the U.S. Federal Communications Commission regulations, here is a list of calling features offered to our land-line telephone service customers.
Hosted VoIP customers have different and more robust calling features and are listed in the bottom section of this page.


900 Restriction

Restricts access to 900 area code and 976-Office Code toll calls. It is activated or deactivated by the service provider.

· This feature applies to outgoing calls.

Automatic Callback

Enables the subscriber to automatically call the last incoming number. If the called party is busy, the system continues to try to make the connection until both parties are idle. This feature is typically invoked after the initial dialing attempt leads to a busy signal. This feature is also known as “*66” and “repeat call.”

Vertical Service Codes

· Activation code: *66 (to re-dial the last number)· Deactivation code: *86 (terminate all current AC requests)

· This feature applies to outgoing calls.

· For BLHG members this feature can only be assigned if the member has a valid DN.

· If AC is performed to a number with ACR, that call is rejected by ACR if the called number is marked “private.”·

Refer to the “Provisioning AC/AR” section of theCSX Family -Provisioning Guidefor more information on the timers associated with this feature.

Anonymous Call Rejection (ACR)

ACR enables the subscriber to automatically block calls from parties whose DNs are marked “Private.” When subscribed and activated, it routes incoming calls to an announcement if the calling party number is marked “Private.”

Vertical Service Codes:
Activation code: *77
Deactivation code: *87

For individual BLHG members this feature can only be assigned if the member has a valid DN.
ACR is applied before call forwarding, call waiting, and TEEN services.
Advanced Do Not Disturb (ADND)
A subscriber who tries to place a call to an idle subscriber, who has the ADND feature active, receives ADND intercept treatment. The calling subscriber can enter a PIN during this tone or announcement after the announcement or tone has ended. If this PIN matches the called subscriber’s PIN, the ADND feature is overridden and the call is extended to the called subscriber.


The following two fields are provisioned on the Subscriber Care window:
ADND PIN -This is the number that the calling subscriber enters. This is a required field. At dial tone or recall dial tone, the subscriber can enter the access code to modify the PIN code.
ADND PIN Length-The maximum number of digits for the PIN. The valid values are 4 to 10. The default value is 4.


Vertical Service Codes:
Activation Code: *51
Deactivation Code: *52
Advanced Do Not Disturb PIN Change: *53


This feature takes precedence over AIN DND.

Automatic Recall

Enables the subscriber to automatically call the last incoming number. If the called party is busy, the system continues to try to make the connection until both parties are idle. This feature is typically invoked after missing an incoming call or to resume the call to the last incoming party.

Vertical Service Codes:
Activation code: *69 followed by a 1 after the confirmation request
Deactivation code: *89 (terminate all current AR requests)
Notes: This feature applies to incoming calls.

· For BLHG members this feature can only be assigned if the member has a valid DN.

· If AR is performed to a number with ACR, that call is rejected by ACR if the called number is marked “private.”

· Select the AR Activation Level. Valid values are:

Level 1-This is the default value and indicates that the feature is activated as soon as the subscriber dials *69.
Leve 2 -Selecting this value indicates that when the subscriber dials *69, the system plays an announcement containing the telephone to be called and asks the subscriber if they want to continue.

· Refer to the “Provisioning AC/AR” section of the CSX Family -Provisioning Guide for more information on the timers associated with this feature.

Basic Business Group

This feature is assigned to individual subscribers or BLHGs when a BBG is created using the Basic Business Group window. The BBG feature is then automatically assigned to all members and displays in the Subscriber CareFeature Administration window for member subscribers. For more information about creating and administering a BBG, refer to the “Basic Business Group” section of the CSX Family – Provisioning Guide.

Call Forwarding Busy

Enables the subscriber to forward incoming calls to another line when the subscriber’s line is busy, up to a limit of five forwarding hops. The Courtesy Call field is used to confirm a remote address when a customer activates the Call Forwarding feature through their telephone keypad. After the forwarded-to number is dialed, the remote telephone rings after a small delay. This enables the originating caller to confirm that the call is going to the correct destination. Also, the person that is called can be informed of the forward-to calls.


If the forwarded call is not answered, the CSX Switching System starts a two-minute timer (for the Answer option and Answer with Confirmation Tone option) when the subscriber goes on-hook. If the subscriber goes off-hook, receives dial tone, dials an activation code, receives recall dial tone, and enters the same remote number before the timer expires, the CSX System will activate the feature and return a confirmation tone in the same way as for an activation without courtesy call.


The Courtesy Call options are as follows:
None – No courtesy call (default)
Answer – The subscriber dials the activation code, hears a stutter dial tone, then enters the forward-to number. The forward-to number rings. When the forward-to number answers, call forwarding is activated.
Answer With ConfTone -The subscriber dials activation code, hears a stutter dial tone, then enters the forward-to number. A confirmation tone is received. When the forward-to number answers, call forwarding is activated.
No Answer -The subscriber dials activation code, hears a stutter dial tone, then enters the forward-to number. The forward-to number rings. When the forward-to number answers or does not answer, call forwarding is activated.
NoAnswerWithConfTone -The subscriber dials activation code, hears a stutter dial tone, then enters the forward-to number. A confirmation tone is received. When the forward-to number answers or does not answer, call forwarding is activated.


The Call Forwarding Limit field is used to limit the number of simultaneously forwarded calls. The valid values are No Limit and 1 to 255. The default value is 1.


Vertical Service Codes:
Activation code: *68 -After *68 is pressed, the subscriber hears a confirmation dial tone. The subscriber then enters the forward-to DN. If the forward-to DN is invalid or if CFBL is already activated, an announcement informs the subscriber.
Deactivation code: *88 -If CFBL is already deactivated, an announcement informs the subscriber.

Call Forwarding Don’t Answer

CFDA is a sub feature of Call Forwarding. This feature enables the subscriber to redirect incoming calls to another line if the subscriber’s line is not answered after a predetermined number of rings. The ring count is set when the feature is assigned to a subscriber.

Call Forwarding Variable

CFV is a sub feature of Call Forwarding. This feature enables the subscriber to redirect incoming calls to another line regardless of the status (busy or idle) of the subscriber’s line. When the call forwarding variable feature is activated, the subscriber’s line, if idle, receives a ring reminder when a call has been forwarded. The subscriber cannot answer calls at the base station while CFV is active but can originate calls.

Call Hold

Enables the subscriber (calling party or called party) to place an active call on hold to activate another feature, such as placing a call or answering another station’s call. When the other feature is completed, the subscriber can re-establish communications with the held party.

Caller Identification

Forwards the calling party’s DN, name, date, and time to the subscriber line during the ringing cycle, if the calling party has not blocked the delivery of their calling identity.

Caller Identification on Call Waiting

Service that enables the subscriber, while on a call, to receive calling party CID or Calling Number Delivery (CND) information. CND or CID must also be assigned for this feature to work.

Calling Identity Delivery/ Suppression

Controls the delivery of caller ID on a per-call basis. This feature is activated to make an anonymous call and is deactivated to show the calling ID again.

Calling Number Delivery

Enables the subscribers to receive a calling party’s DN during the ringing cycle, if the calling party has not blocked the delivery of the calling party number.

Call Transfer

Similar to TWC except when the originating subscriber disconnects, the call gets transferred between the two remaining parties. The feature can also enable a quick conference by enabling the subscriber to dial an add-on party and hook-flash before the party answers.

Call Waiting Operation

Enables the subscriber to know there is an incoming call while they are on the line. The subscriber receives an audible tone (that only the subscriber can hear) and the calling party receives audible ringing. The subscriber may answer the new call by one of two methods. 1. The subscriber can hook-flash, placing the original call on hold and answer the new call. 2. The subscriber can hang up. The telephone rings and the subscriber can pick it up.

Denied Termination

Prevents the subscriber from receiving calls (except for emergency ring back or Traffic Service Position System). 

Denied Origination

Prevents the subscriber from placing calls (except 611 and 911).

Enhanced Telemarketing Do Not Disturb

Enhanced version of the basic Telemarketing Do Not Disturb, providing subscribers an alternative method of handling telemarketing calls. Only calls that have calling numbers that are available and allowed to be present are connected to the subscriber line without receiving an intercept announcement.

Public Feature Code

This Advanced Intelligent Network (AIN) trigger is supported for subscribers on the CSX System by the Innovative Systems Application Peripheral (AP). The CSX System encounters the Public Feature Code (FCD) trigger when it receives a vertical service code (for example, *XX) from the system. Although several vertical service codes may cause the FCD trigger, the CSX System does not differentiate between the codes by subscription (for example, *46, *53, and *58 cause the trigger for all subscribers). 

Flex ANI II Digits

A line with this feature will have the FANI class mark and be assigned the two ANI II digits entered in the ANI II Digits field.

Family Time

Enables a subscriber to have scheduled Selective Call Acceptance (SCA) and/or Selective Call Forwarding (SCF) to be activated at specific days in a week and within a specific time of a day. FT features can be assigned to the primary DN and secondary DNs. The schedule for Family Time can be modified at any time through the Subscriber Care window or the Subscriber Self-Care Web portal.

Hot Line Feature

Automatically places a call to a specified DN as soon as the subscriber’s telephone goes off-hook. If this feature is selected, enter the number to call in the Hot Line DN field on the Subscriber Care window.

Music on Hold

Provides music or announcements to calls placed on hold by the Call Hold (CHD) or Call Park (CPRK) features. While on hold, the held or parked party hears the music or announcements until the person hangs up or is taken off hold.

Multiple Pic

Feature to assign multiple Primary Interexchange Carriers (PICs) for the different routing types. Refer to the “Assigning Carriers” section of the CSX Family – Provisioning Guide for more information on the PICs used by the system. If MULTIPIC is selected on the Subscriber Care window, enter a valid PIC for one or more of the routing types in the associated fields.

Nuisance Call

Logs the subscriber’s originating and terminating calls in the Nuisance Log file. Refer to the “Nuisance Log” section in the “Log” chapter of the CSX Family – Maintenance and Troubleshooting Guide for information on viewing the log file.

Night Service

A scheduled version of the Call Forwarding Variable (CFV) feature. Night Service enables the subscriber to redirect incoming calls to another line if the current time falls within the schedule of this feature. The NS feature can only be activated when the forward-to number is specified. The feature can be assigned to primary DN and secondary DNs. NS is primarily used by business customers.

Off-Hook Delay

This Advanced Intelligent Network (AIN) trigger is supported for subscribers on the CSX System by the Innovative Systems Application Peripheral (AP). When subscribed, a trigger is recognized immediately upon detection of a call attempt from the originating facility that has the trigger assigned to it. This OHD trigger is detected when the caller goes off-hook. However, an SCP or local query is delayed until digit collection is completed. The CSX System suspends call processing and launches a query to the SCP for further instructions. The SCP can instruct the SSP to do various things, such as block the call, route the call to a specified number, or play an announcement.

Remote Access to Call Forwarding

Enables a subscriber to activate or deactivate their call forwarding feature from a remote line. The subscriber dials the number provisioned for this and is prompted for their 10-digit home telephone DN followed by another prompt for their five-digit Personal Identification Number (PIN). After the PIN is accepted, the system prompts for the subscriber’s choice: 1) Activation, which includes changing the Forward-to number, 2) Deactivation, or 3) change the PIN.

Selective Call Acceptance

Enables the subscriber to receive calls only from those DNs in the screening list. If a call arrives while SCA is activated from a DN that is on the selective list, the call is accepted and rings through. If the incoming call is from a DN that is not on the selective list, the call is rejected with an announcement.

Selective Call Forwarding

Similar to Call Forwarding except that the call is forwarded only if it originates from a DN in the screening list. If a call arrives while SCF is activated and the call originates from a DN on the selective list, the call is forwarded. If the incoming call is from a DN that is not on the selective list, the call rings through and is not forwarded.

Selective Call Rejection

Enables the subscriber to reject (block) incoming calls based on a list of DNs to be rejected. If a call arrives while SCR is activated and the call originates from a DN on the selective list, the call is rejected with an announcement. If the incoming call is from a DN that is not on the selective list, the call rings through and is not rejected.

Selective Distinctive Ringing/ Call Waiting

Enables a subscriber to define a list of DNs with special incoming call treatment. Any incoming calls from DNs on the selective list are indicated by a distinctive ringing pattern or a distinctive Call Waiting tone. Any incoming calls from DNs that are not on the selective list rings through as normal. SDRCW combines the Selective Distinctive Ringing (SDR) and Call Waiting (CW) features together.
