Isn't There Something Like BARS 101?
Posted: 12 Mar 06 (Edited 15 Jan 11)

The Origonal BARS101 was published by GHTROUT in 2001, and can be found in basic HTML format at http://www.ghtrout.com/
Yes!
Basic Automatic Route Selection. If you dial "9", you are accessing BARS. "9" is the "BARS Access Code"
1. A telephone dials "9" - BARS activates.
2. The telephone dials a number - Example: 1312-XXX-XXXX
3. The PBX holds the digits while it looks up "1312" to figure out what Route List to use for processing the call.
4. The Route List determines the possible trunk routes that can be used.
5. The Route List checks the facility restriction level of the telephone and compares it to its own required facility restriction level.
6. The Route List checks to see if any special digit manipulation should be performed.
LD90 NET
The LD90 Network overlay is where area codes and exchanges are defined. If a prefix is not entered into LD90, it cannot be dialed through BARS. Each area code or exchange refers to a "Route List" or RLI which contains the instructions for routing the call.

LD86 RLB (or RLI)
The RLB is a "list" of possible trunk routes that an area code or exchange (NPA, NXX, SPN) can be selected for the call. Each "ENTR" or list entry contains a trunk route. Each entry also has a "minimum Facility Restriction Level" or "FRL" that must be met or exceeded before a phone can access that entry.
In the following example, the first ENTR can be accessed by phones whose NCOS equals an FRL of 3 or above. The second entry can only be accessed by phones whose NCOS equals an FRL of 6 or above. For example, less important phones might be NCOS 3 and very important phones might be NCOS 6. If all trunks in the first route choice were busy, only important phones would have access to the trunks in the second route choice.
Along with the trunk route and the FRL, you can apply specific "digit manipulation" with the DMI entry. The DMI entries are explained here.

LD87 NCTL
The FRL to NCOS "relationship" is built in the NCTL data block. The FRL and the NCOS do not necessarily have the equal one another, however they usually do. A higher FRL/NCOS has more capability than a lower FRL/NCOS. For an NCOS number to have any capability, it must first be defined in the NCTL data block.

LD86 Digit Manipulation
The Digit Manipulation data blocks are where special prefixes are entered before numbers are sent out over trunks. An example of digit manipulation is where a 1010XXX carrier access code must be inserted before a number is processed over a trunk.
