Analog Line Ports
Overview
What It Is
Service providers who are collocated in a Verizon central office can access an Unbundled Analog Line Port in that office. The port consists of a 2-wire electrical interface to our local switch. It transmits analog voice grade signals between 300 and 3000 Hz. These ports service single line residential or business applications and have loop or ground start supervisory signaling and Dual Tone Multi-Frequency (DATMF) address signaling capabilities.
Analog Line Ports support features such as vertical services like Call Forwarding, hunt group options, basic intercept, custom calling, usage recording and many others. Some port features are optional and are provisioned for an additional charge.
How It Works
The Unbundled Analog Line Port uses a variety of supervisory signaling methods to control call processing. Two-wire interfaces connect to our local switching system via a 2-wire central office distribution frame cross-connect between your 2-wire distributing frame termination and that of the analog port.
Description
The analog line port provides a 2-wire electrical interface to the local switch.
Analog unbundled port services provide the service provider, collocated in a Verizon central office, access to analog switch ports on Verizon local switching systems. Both the service provider's collocation arrangements and the analog unbundled port must reside in the same Verizon central office.
The analog line port can be terminated to a Platform where available.
The basic analog line port is applicable to single line residential or business service. The basic analog port is provided with loop-start or ground start supervisory signaling and Dual Tone Multi-Frequency (DTMF) address signaling capabilities.
Availability
Analog Line Ports are available throughout the Verizon Footprint.
Pricing
Line ports are assessed monthly recurring charges. In addition, usage charges apply. A Non-Recurring Charge (NRC) is assessed for installation as well as a service order charge per order. There is an additional charge for activation of an additional channel or telephone number on an established line port. There are also charges for the activation of one or more features on an established line.
Pricing and applicable USOCs may vary by state jurisdiction and pursuant to individual carrier interconnection agreements.
See your federal and state tariffs for detailed information.
In Pennsylvania only, the Analog Line Port has an additional offering (Option B), which will provide all vertical features except for 3 Way Calling, Distinctive Ringing, Calling Number Delivery Blocking and Centrex Intercom. These features can be ordered separately on an individual basis.

The following features, some of which may require an additional charge, are representative of vertical features available in central office switches:
| Feature Name | Comments |
| Telephone Number | |
| Basic Intercept | |
| Primary Interexchange Carrier | |
| E911 | Verizon will update E911 and Directory Listing - For CLEC port, CLEC updates E911; For CLEC port, Verizon updates DL; For CLEC port, Verizon is responsible for updating LIDB; For INP - LIDB must be restated by CLEC, but E911 will be retained; For E911, Verizon unlocks the record and turns the control of updating the ALI database over to the CLECs for update. Verizon will take down LIDB. |
| Operator | Ability to access operator through proper combination of UNEs made by CLEC. |
| Blocking (per line) | Please refer to section following for additional information on Blocking. |
| Speed Calling (8 or 30) | |
| 3 Way Calling | |
| Call Forwarding | Call Forwarding to another number. |
| Call Forwarding Busy Line | A Line may have both Call Forwarding Busy Line and Call Forwarding Don't Answer. |
| Call Forwarding Don't Answer | Call Forwarding to another number after a certain time period or a certain number of rings. |
| Distinctive Ringing | |
| Anonymous Call Rejection | This option redirects incoming calls for which calling name and number display have been suppressed through the use of Per-Call Blocking or Line Blocking. The caller receives an announcement indicating that the line is not presently accepting such calls. The option is activated and deactivated by dialing a code. (Initially, the feature is in the deactivated state.) |
| Any of the following: Call Forwarding, Call Forwarding Busy, Call Forwarding Don't Answer, Call Forwarding Variable | Re-directs all incoming calls so that they may be answered at another line port. When a CLEC with more than one central office line grouped for incoming service has the Call Forwarding transfer in effect on a line in the series, the calling party receives a busy signal if the number to which calls are being transferred is busy. The call is not completed to the next available line in the incoming service series. When the Call Forwarding transfer is deactivated, the incoming service grouping is restored to normal operation. Calls cannot be transferred to an International Direct Distance Dialing number. |
| Caller ID with Call Management | This option is an augmented form of Caller ID, which also allows a line which is off-hook on an existing call to receive Caller ID information (number only) for a new incoming call, and to handle the new call by either: Forwarding to a call answering service Including in conferencing Routing to a message announcement, or Drop First/Drop Last Caller option. The line needs to be equipped with Call Waiting to take full advantage of this option. Lines equipped with Caller ID with Call Management are also provided automatically with the Anonymous Call Rejection option. |
| Caller ID with Name | This option is an augmented form of Caller ID, but also includes end user name. The service is only available with special customer premises equipment. |
| Call Return | This option is activated by dialing a special code which automatically returns the most recent incoming call (even if it is not answered), or provides an audible announcement of the telephone number, date, and time of the last incoming call. This option permits the call to be automatically returned by dialing another code. If the called number is busy, the call is attempted for a maximum of 30 minutes without tying up the end user's telephone. Should the line become idle during this process and the Call Return end user's line be available to complete the call, a distinctive ringing signal alerts the Call Return line that the call can be completed. |
| Call Waiting | This option provides a tone signal, which indicates to a line port already connected on a telephone call that a second call is waiting. It also permits the line port to hold the first call, answer the second call, and then alternate between both calls. When a line is equipped for both Call Waiting and Call Forwarding Variable, Call Waiting does not operate when a call is being forwarded or when a forwarded call has been connected to the forwarding point. When two lines served by the same central office switch and equipped for Call Waiting have a call in progress, only one line may receive a call over Call Waiting. Any incoming call to the other line receives a busy signal, and the CLEC's end user does not receive the tone signal indicating that a call is waiting. |
| Call Waiting ID Or Call Waiting with Name | This option is an augmented form of Caller ID, designed for use by Call Waiting equipped ports to indicate that a line port is off the hook on an existing call and available to receive Caller ID information (number only or number with name) for a new incoming call. |
Applications
The analog line port provides access to the functions and capabilities of the local switch including:
Line supervision
Dial tone
Ringing
Digit reception and interpretation
Network address (the local directory number) billing recording
The ability to pre-subscribe to a primary carrier of InterLATA service
The ability to pre-subscribe to a primary carrier of IntraLATA service (toll region to region calls)
Analog line ports consist of a 2-wire analog interface associated with a local switching system and a 2-wire central office distributing frame cross-connect between a 2-wire service provider's distributing frame termination and the distributing frame termination of the analog port. At each 2-wire interface, one conductor is called tip and the other conductor is called ring.
Analog line ports provide a local switch interface that is suitable for the transmission of analog voice grade signals between approximately 300 and 3000 Hz. Analog line ports use various methods of supervisory signaling to control call processing.
