# Line Numbers

One configuration choice for you to determine is which lines to enable. Lines enabled in the CDR Configuration Menu have their call traffic saved as CDR records.

Each line number is expressed as a triplet, where module, slot, and port number are separated by colons (:). If you have a one-module server, you can refer to just the slot and port number. If you have a multi-module server, you must specify the module number as well, or the server assumes you are configuring Module 1 only.

Note: Support for multiple-module servers (e.g. NPM UM 640) was discontinued with NuPoint Release 6.0.

Module (Host) | Slot | Port (virtual)
--- | --- | ---
NuPoint UM 60 ports = always 1 NuPoint UM 120 ports = always 1 NuPoint UM 640 = specify 1 or 2 (default is 1) | Always 0 for mail ports. Always 5 for fax ports. | 0 - licensed port limit, no duplicates allowed OR * for all ports

An example of a triplet is 1:0:2. This means Module 1, Slot 0, and Port 2. This is distinct from 2:0:2, which would be on Module 2, and from 1:0:1 which is Port 1 on the same Module and Slot as the first case. Triplets do not use colons when stored in CDR records; module, slot, and port are two-character numerics in a six-character field. The above triplet is stored by CDR as 010002.

When configuring Line Numbers for CDR, you have several menu options that help you set up the lines you want to monitor. The Enable all Lines option chooses every line in your server automatically. You do not have to worry about how many modules, ports, or lines you have. If you want to use CDR on a subset of your lines, the Enable Individual Lines and Disable Individual Lines options are available. You can specify which lines to add to or subtract from the list of monitored lines. The Show Individual Lines option displays the list of lines that are monitored by CDR.

You can use the wildcard character (*) when specifying which lines to enable or disable. For example, the triplet 2:0:* represents all lines on Module 2, Slot 0. The expression 1:* represents all ports and lines on Module 1 (the second wildcard is redundant). Use the Enable and Disable options to add or remove lines, and the Show option to verify your selection. If you wish to enable all but a very few lines, your easiest course is to Enable All Lines, then Disable the lines you do not want. You must exit the CDR Configuration Menu in order to save any changes made within these options.

Download your data frequently if you enable all lines; this is the maximum data possible and overwriting can occur if CDR space is used up.

Note: If you enter a triplet and leave out one set of numbers, the server assumes you are specifying Module 1. For example, if you enter 0:4, it assumes Module 1, Slot 0, Port 4.
